RH7062A-1.5-21/1J0973713/1813139-1 12 V, 6 Position, Automotive Housing for Female Terminals

Detailed Product Description

The RH7062A-1.5-21/1J0973713/1813139-1 is a high-performance, fully sealable 6-position automotive housing connector engineered for 12V applications across wire-to-board, wire-to-device, and wire-to-wire systems. This rectangular connector features a 6-position, 2-row configuration (2x3), specifically designed for 1.6mm female receptacle terminals with a 10A maximum current rating per contact. Featuring a black PBT (Polybutylene Terephthalate) housing, keying code 1, Terminal Position Assurance (TPA) , primary locking on the terminal, 4mm centerline pitch with matching 4mm row-to-row spacing, and a compact 31.4mm x 31.4mm footprint, this fully sealable connector delivers reliable power and signal transmission in demanding automotive, commercial vehicle, and industrial applications across a temperature range of -40°C to 120°C.

An important feature is that strain relief is added by accessory – this allows users to add strain relief as needed for specific applications, providing design flexibility.

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 1.6mm 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

The primary locking feature is on the terminal – this is a critical design distinction. Unlike locking lance housings where the housing retains the terminal, this design places the retention mechanism directly on the terminal. 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

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, 2-Row (2x3) Design

The housing provides 6 positions arranged in 2 rows (3 positions per row). This 2x3 configuration offers:

Balanced, compact footprint – efficient use of space

Good contact density – 6 positions in a moderate package size

Simplified routing – two-row design is easy to integrate into harnesses

Symmetrical design – 31.4mm x 31.4mm nearly square footprint with 4mm row-to-row spacing matching contact pitch

Electrical Characteristics – 12V Dedicated System
This connector is rated for 12V nominal voltage architecture, making it specifically designed for:

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

The 12V dedicated design ensures optimal creepage, clearance, and insulation for this voltage level, while the 10A current rating provides ample capacity for mixed power and signal applications.

Body Features – Black Housing with Keying Code 1

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 1, indicating a specific keying configuration to prevent mismating with connectors having different keying codes. Keying ensures that only connectors with matching code 1 can be mated correctly.

Contact Features – 1.6mm, 10A Terminals

The housing accepts receptacle-type contacts (female terminals) with a contact size of 1.6mm. The mating tab width is precisely 1.6 mm (0.063 in) . The maximum contact current rating is 10A per contact.

The 1.6mm contact system is a versatile size suitable for:

Mixed power and signal applications – 10A capacity handles moderate power loads

Sensor and actuator circuits – reliable signal and low-power transmission

Lighting circuits – interior and exterior LED lighting

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

Small motors and solenoids

The 1.6mm size offers a balance between the ultra-compact 0.64mm signal terminals and larger 2.8mm power terminals, making it ideal for applications needing both moderate current and reasonable density.

Mechanical Attachment – With TPA and Accessory Strain Relief

Mating alignment is provided with a keyed alignment type (keying code 1). Keyed connectors use asymmetric plastic features to physically prevent incorrect mating.

Terminal Position Assurance (TPA) is provided – Yes. This is a critical safety feature. TPA is a secondary locking device that independently locks terminals into the housing after initial insertion. TPA provides:

Prevents terminal back-out – stops terminals from loosening due to vibration or thermal cycling

Visual confirmation – clear indicator that all terminals are fully seated

Redundant retention – adds secondary retention beyond the primary terminal-based locking

Safety critical – required for high-reliability applications

Strain relief is added by accessory (Strain Relief: Add By Accessory) – this is a flexible design feature. The connector housing does not include integrated strain relief, but it is designed to accommodate external strain relief accessories such as:

Cable ties – through integrated slots or channels

Heat shrink boots – overmolding or adhesive-lined heatshrink

Conduit fittings – for flexible conduit protection

Custom overmolding – for ruggedized applications

This allows users to add strain relief only when needed, reducing cost for applications where cable movement is minimal, while providing the option for harsh environments.

Connector mounting type is Cable Mount (Free-Hanging) , offering maximum flexibility for harness assembly.

Housing Features – PBT Material

The housing is manufactured from Polybutylene Terephthalate (PBT) . PBT is a high-performance engineering thermoplastic offering:

Excellent dimensional stability – maintains precise tolerances across temperature and humidity variations

High heat resistance – retains mechanical properties at 120°C maximum operating temperature

Low moisture absorption – critical for sealable connectors to maintain dimensional stability

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

Good dielectric properties – suitable for 12V insulation requirements

Creep resistance – maintains terminal retention force over time

Cost-effective – offers excellent performance at a competitive price

The centerline (pitch) between adjacent contacts is 4 mm (0.157 in) , and the row-to-row spacing is also 4 mm (0.157 in) , creating a perfectly symmetrical square grid. This matched spacing offers:

Symmetrical design – same spacing horizontally and vertically simplifies PCB layout for wire-to-board applications

Adequate electrical spacing – sufficient creepage and clearance for 12V systems and 10A current

Scalable – 4mm pitch is common, ensuring compatibility with standard tooling
