This rectangular connector features a unique single-row (1-row) configuration with 6 positions, specifically designed for 1.5mm female receptacle terminals with a 14A maximum current rating per contact. Featuring a black PA 66 GF (glass-fiber reinforced) housing, keying code Neutral, primary locking on the terminal, polarizing slot mating alignment, and a wide 6mm centerline pitch with a compact 36.8mm x 36.8mm footprint, this fully sealable connector delivers reliable power and signal transmission in next-generation 48V mild hybrid systems as well as traditional 12V and 24V applications across an extreme temperature range of -40°C to 125°C.

Product Type Features – Fully Sealable with Terminal-Based Locking

This connector features a rectangular shape, providing efficient space utilization. It is a non-mixed, non-hybrid connector, meaning all 6 positions accept identical 1.5mm female receptacle terminals, simplifying inventory management. As a housing for female terminals, it is designed to mate with corresponding male terminal housings, headers, or device connectors.

The connector is fully sealable (Sealable: Yes) – this critical feature provides:

Environmental protection – excellent resistance to moisture, dust, salt spray, and contaminants

Underhood and exterior suitability – can be used in engine compartments and outdoor locations

IP rating capable – when properly assembled with sealed terminals and cavity plugs

48V system readiness – sealing is critical for high-voltage systems to prevent creepage and corrosion

The primary locking feature is on the terminal – this design places the retention mechanism directly on the terminal rather than in the housing. Terminal-based locking offers:

Simpler housing design – reduces housing complexity and tooling costs

Terminal replaceability – individual terminals can be removed and replaced more easily

Proven reliability – terminal-based locking is a mature, widely used approach

Lower insertion force – terminals can be inserted without overcoming housing lance resistance

Smoother assembly – consistent insertion feel across all positions

The connector system is exceptionally versatile, supporting wire-to-board, wire-to-device, and wire-to-wire configurations. This triple-system capability means the same connector housing can be used to connect:

Wire-to-board – harness to PCB-mounted header

Wire-to-device – harness directly to sensors, actuators, motors, or ECUs

Wire-to-wire – harness-to-harness connections

The connector terminates to wire and cable.

Configuration Features – 6-Position Single-Row Design
The housing provides 6 positions arranged in 1 row. This single-row configuration offers several advantages:

Easy terminal access – all 6 terminals are visible and accessible from one side

Simplified inspection – visual verification of terminal insertion and sealing is straightforward

Low profile potential – single-row design allows for efficient space utilization

Daisy-chain friendly – ideal for applications requiring multiple connections along a wiring run

Sealing-friendly – single-row design simplifies the sealing interface

Reduced risk of terminal mix-up – no confusion between rows

The 6-position count is a practical solution for applications requiring 6 circuits without the extra size of 8-position connectors.

Electrical Characteristics – Triple Voltage Capability (12V/24V/48V)

This connector is uniquely rated for triple nominal voltage architectures: 12V, 24V, and 48V. The operating voltage (VDC) is 24V, providing adequate margin for 12V and 24V systems while supporting 48V architectures. This triple-voltage capability makes the connector exceptionally versatile across current and future vehicle platforms:

12V systems – standard passenger cars, light-duty vehicles, and traditional automotive applications

24V systems – heavy-duty trucks, commercial vehicles, buses, construction equipment, agricultural machinery, and marine applications

48V systems – mild hybrid electric vehicles (MHEV), electric power steering (EPS), e-turbochargers, active suspension systems, electric air conditioning compressors, and emerging 48V architectures

As the automotive industry increasingly transitions to 48V mild hybrid systems for improved fuel efficiency and reduced emissions, this connector is future-ready for next-generation electrical architectures while maintaining backward compatibility with 12V and 24V systems. The 14A current rating provides ample capacity for mixed power and signal applications across all three voltage platforms.

Body Features – Black Housing with Neutral Keying Code

The cable exit angle is 180° (straight) , facilitating straightforward cable management and minimizing bend stress on wires. The primary product color is Black, providing a professional appearance along with good UV resistance and thermal stability.

The connector and keying code is Neutral – this is a significant feature. Unlike connectors with specific keying codes (A, B, C, D, 1, 2, etc.), a Neutral keying code means:

No polarization restriction – the connector can mate with a broader range of counterparts

Universal compatibility – may be designed to accept multiple keying variants or serve as a default orientation

Simplified logistics – fewer SKUs needed for mating components

Service-friendly – reduced risk of ordering wrong keying code

The Neutral designation indicates that this connector is designed for maximum compatibility within its connector family.

Contact Features – 1.5mm, 14A Terminals

The housing accepts receptacle-type contacts (female terminals) with a contact size of 1.5mm. The mating tab width is precisely 1.5 mm (0.06 in) . The maximum contact current rating is 14A per contact.

The 1.5mm contact system is a versatile size offering:

Excellent balance – between the ultra-compact 0.64mm signal terminals and larger 2.8mm power terminals

14A capacity – handles moderate to high power loads

48V compatibility – appropriate creepage distance for higher voltage systems

Mixed power and signal suitability – ideal for applications needing both moderate current and reasonable density

Sensor and actuator circuits – reliable signal and power transmission

Lighting circuits – interior and exterior LED and traditional lighting

Control module I/O – ECU, BCM, TCU connections

Small motors and solenoids

Mechanical Attachment

Mating alignment is provided with a polarizing slot alignment type. A polarizing slot is a specific geometric feature (a slot or groove) molded into the housing that works with a corresponding rib on the mating connector to ensure correct orientation. This provides:

Positive polarization – physical prevention of reverse or incorrect mating

Visual alignment aid – easy to see when properly aligned

Smooth mating – guides the mating connector into correct position

No keying code restriction – complements the Neutral keying code by providing mechanical polarization without limiting compatibility

Terminal Position Assurance (TPA) is not provided (No) . Without TPA, proper terminal insertion relies on the primary locking feature on the terminal itself. Installers should ensure terminals are fully seated until an audible click confirms engagement of the terminal's locking lance.

Strain relief is not provided (Without) – for high-vibration applications, external strain relief such as cable ties, heat shrink boots, or conduit is recommended.

The connector mounting type is Cable Mount (Free-Hanging) , offering maximum flexibility for harness assembly without requiring panel or PCB mounting.

Housing Features – PA 66 GF Reinforced Material

The housing is manufactured from PA 66 GF (Polyamide 66 with Glass Fiber reinforcement) . This advanced material offers exceptional properties for demanding sealable and high-voltage applications:

Benefits of glass-fiber reinforced PA 66:

High mechanical strength – GF reinforcement provides excellent tensile and flexural strength

Excellent dimensional stability – minimal warpage and shrinkage, critical for sealable connectors and 6mm pitch accuracy

Superior heat resistance – maintains properties at 125°C maximum operating temperature

High creep resistance – maintains terminal retention and sealing compression over time and thermal cycling

High stiffness – resists deformation under terminal insertion and mating forces

Good chemical resistance – withstands automotive fluids including engine oil, fuel, and coolant

Low moisture absorption – better than unfilled PA66 for sealable applications

Dielectric strength – appropriate for 48V insulation requirements

The centerline (pitch) between adjacent contacts is 6 mm (0.236 in) – a wide pitch that offers significant benefits, especially for 48V applications:

Enhanced electrical spacing – provides superior creepage and clearance distances required for 48V systems (which can have voltage spikes significantly higher than nominal)

High-voltage safety margin – even though rated for 48V nominal, the wide pitch provides safety margin for voltage spikes or system faults

Accommodates larger wire gauges – 6mm pitch allows easy termination of thicker wires needed for 14A current (typically 14-16 AWG)

Reduced crosstalk – greater physical separation minimizes capacitive and inductive coupling between adjacent circuits

Improved heat dissipation – more air gap around each contact allows better cooling

Simplified assembly – more room between terminals makes inspection, rework, and insertion easier

Sealing compatibility – wide pitch allows for robust wire seals and cavity plugs

The 6mm pitch is approximately 2.4 times wider than standard 2.54mm signal connectors and 1.2 times wider than typical 5mm power connectors, making it particularly suitable for 48V applications where electrical spacing is critical.

Dimensions – Compact Square Footprint

Connector Height: 32.2 mm (1.268 in)

Product Length: 36.8 mm (1.449 in)

Product Width: 36.8 mm (1.449 in)

The RH7061Y-1.8 features a compact, square footprint – length and width are both 36.8mm, forming a perfectly square connector body with a height of 32.2mm. This square shape offers:

Symmetrical design – no orientation preference for harness routing

Efficient panel utilization – fits well in square cutouts or mounting areas

Balanced mechanical strength – uniform wall thickness in both directions

Aesthetic appearance – professional, clean look

The 36.8mm x 36.8mm width/length provides a stable, robust connector body with ample material for sealing features, terminal retention, and the 6mm pitch spacing. The 32.2mm height accommodates the single-row design with sealing interfaces and polarization features.

Sealable Construction

As a fully sealable (Sealable: Yes) connector, the RH7061Y-1.8 incorporates specific design elements:

Wire seals – around each wire entry point for 1.5mm terminals (accommodating appropriate wire gauges for 14A)

Cavity plugs – for unused positions to maintain seal integrity

Interface seal – between mating connector halves

Seal retention features – to keep seals in place during assembly and use

To maintain seal integrity, especially critical for 48V systems where moisture ingress can cause creepage and corrosion issues:

All 6 positions must be filled with either terminated wires (with proper seals) or cavity plugs

Mating connector (board header, device connector, or another housing) must also be sealable or used in dry environments

Proper assembly techniques are required to avoid seal damage

For 48V applications, seal integrity is particularly important to prevent high-voltage creepage paths
