Product Type Features – Fully Sealable with Clean Body 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 0.64mm female receptacle terminals, simplifying inventory management. As a housing for female terminals, it is designed to mate with corresponding male terminal headers on PCBs.

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

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

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

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

The primary locking feature is Clean Body – this is a distinctive design where the housing exterior maintains a smooth, clean surface without external locking latches or protrusions. Clean Body design offers:

Smooth external profile – no snagging on wires, harness wraps, or during installation

Reduced packaging space – no protruding latches to accommodate

Aesthetic appearance – clean, professional look

Integrated locking – retention features are contained within the housing geometry

The connector system is wire-to-board, specifically designed to connect wiring harnesses to printed circuit board headers. The connector terminates to wire and cable.

Configuration Features – 6-Position Single-Row with Blank Cavity
The housing provides 6 positions arranged in 1 row – a single-row configuration that offers:

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

Simplified inspection – straightforward visual verification

Low profile – efficient space utilization in height-constrained applications

Blank Cavity Position: 1 – indicates that one of the 6 positions is designated as a blank cavity (no terminal used). This means the connector effectively provides 5 active circuits with 1 position reserved for sealing or future expansion. The blank cavity must be filled with a cavity plug to maintain seal integrity.

Electrical Characteristics – 12V Signal/Low-Power System

This connector is rated for 12V nominal voltage architecture, making it specifically designed for:

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

The 12V dedicated design ensures optimal performance for signal-level and low-power circuits, not high-current power distribution.

Body Features – Black Housing with Keying Code B

The cable exit angle is 180° (straight) , facilitating straightforward cable management. The primary product color is Black. The connector and keying code is B, indicating a specific keying configuration to prevent mismating with connectors having different keying codes. Keying code B ensures correct mating orientation.

Contact Features – 0.64mm Miniature Terminals

The housing accepts receptacle-type contacts (female terminals) with a contact size of 0.64mm. The mating tab width is precisely 0.64 mm (0.025 in) – this is a miniature terminal size commonly used for:

Signal circuits – sensors, switches, control signals

Low-current power – LED lighting, small solenoids, display backlighting

Data transmission – CAN bus, LIN bus, other communication protocols

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

The 0.64mm contact system is the industry standard for low-current automotive signal applications, offering high density and reliable performance.

Mechanical Attachment – With TPA (Terminal Position Assurance)

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

Terminal Position Assurance (TPA) is provided – Yes. This is a critical feature for this connector. 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

Visual confirmation – clear indicator that all terminals are fully seated

Redundant retention – adds secondary retention beyond the primary Clean Body locking

Safety critical for signal integrity – ensures reliable signal transmission

Note: For sealable connectors with TPA, the TPA may also assist in compressing or retaining wire seals.

Strain relief is not provided (Without) – external strain relief such as cable ties or heat shrink may be used where needed.

The connector mounting type is Cable Mount (Free-Hanging) , designed to plug into a board-mounted header.

Housing Features – PA 66 GF35 High-Performance Material

The housing is manufactured from PA 66 GF35 (Polyamide 66 with 35% Glass Fiber reinforcement) . This high-reinforcement material offers exceptional properties:

Benefits of 35% glass fiber reinforcement:

Very high mechanical strength – 35% GF provides significantly higher tensile and flexural strength than lower reinforcement levels

Excellent dimensional stability – minimal warpage and shrinkage, critical for fine-pitch (2.54mm) sealable connectors

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

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

High stiffness – resists deformation under terminal insertion and mating forces

Good chemical resistance – withstands automotive fluids

The 35% glass fiber content is the highest reinforcement level in this product family, chosen for demanding applications requiring maximum dimensional stability and mechanical strength, particularly important for the fine 2.54mm pitch and sealable design.

The centerline (pitch) between adjacent contacts is 2.54 mm (0.1 in) . This fine pitch is a critical feature:

High contact density – fits 6 contacts in a compact length of approximately 15mm (6 × 2.54mm)

Industry standard – 2.54mm (0.1 inch) is a common pitch for signal connectors, compatible with standard PCB headers

Space efficient – ideal for applications where board space is limited

Signal optimized – pitch appropriate for low-current signal circuits, not high-power

Dimensions – Compact Signal Connector Footprint

Connector Height: 19.6 mm (0.772 in)

Product Length: 31.4 mm (1.236 in) – includes alignment and keying features

Product Width: 25.4 mm (1.0 in) – exactly 1 inch, accommodating the single row of 6 contacts with 2.54mm pitch plus TPA and sealing features

The RH7065YB-1.2 features a compact, signal-optimized footprint. The 25.4mm width provides exactly 1 inch of space, compatible with standard board layouts. The 31.4mm length accommodates the 6 positions plus mating alignment features. The 19.6mm height provides a low profile suitable for space-constrained installations.

Sealable Construction

As a fully sealable (Sealable: Yes) connector, the RH7065YB-1.2 incorporates specific design elements:

Wire seals – around each wire entry point (0.64mm terminal size requires small wire gauges, typically 18-22 AWG)

Cavity plugs – for unused positions, including the designated blank cavity position

Interface seal – between mating connector halves

TPA integration – TPA may assist in seal retention

To maintain seal integrity:

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

The blank cavity position (position 1) is not for active use – it must contain a cavity plug

Mating header must also be sealable or used in a dry environment

Usage Conditions – Extended Temperature Range

The operating temperature range spans from -40°C to 125°C (-40°F to 257°F) , with a maximum sustained operating temperature of 125°C (257°F) . This range makes the sealable signal connector suitable for:

Engine compartments – moderate temperature areas

Transmission environments

Underbody applications – protected locations

Commercial vehicle interior and exterior

The PA 66 GF35 housing maintains dimensional stability and sealing integrity across this entire range, while the 0.64mm contact system is designed for reliable signal transmission even at extreme temperatures.
