RH7065-6.3-21/880297-1 6 Position Automotive Connector for Female Terminals

Detailed Product Description

The RH7065-6.3-21/880297-1 is a robust, non-sealable 6-position automotive connector engineered as a receptacle housing for female terminals in wire-to-wire power applications. This rectangular connector features a 6-position configuration, straight terminal orientation, and an industry-leading 9.14mm wide centerline pitch – one of the largest pitches available in this product family. Featuring a natural (uncolored) Polyamide housing, mating alignment features, and cable mount (free-hanging) design, this connector delivers reliable, high-spacing power transmission in applications requiring large wire gauges, high voltages, or circuits where electrical separation is critical. The connector operates across a temperature range of -40°C to 105°C.

Product Type Features

This connector is designed as a receptacle – the female side of a connection system that accepts male terminals or headers. As a housing for female terminals, it is specifically engineered to house receptacle-type contacts that mate with corresponding male tab terminals. The connector and contact terminates to wire and cable, making it suitable for harness assembly.

The connector is non-sealable (Sealable: No) , making it suitable for interior, under-dash, or dry underhood environments where moisture ingress is not a primary concern. This design choice reduces cost compared to sealed alternatives while maintaining excellent electrical and mechanical performance.

Configuration Features

The housing provides 6 positions for female receptacle terminals. Unlike many 6-position connectors that use 2-row or 3-row configurations to save space, this connector’s specific configuration emphasizes electrical spacing over density – the wide 9.14mm pitch naturally leads to a larger housing that prioritizes creepage and clearance distances.

Contact Features – Receptacle with Straight Orientation

The terminal type is Receptacle – these are female contacts designed to accept male tab terminals. The terminal orientation is Straight – terminals are inserted straight into the housing from the rear (wire-entry side) and remain in a straight, in-line orientation relative to the connector body. Straight orientation offers:

Simpler assembly – terminals are inserted along the natural wire direction

Reduced stress – no bending of terminals or wires inside the housing

Lower insertion force – straight insertion requires less force than right-angle configurations

Reliable retention – straight terminals provide consistent normal force on mating tabs

The contact mating retention is Without – this means the connector housing does not incorporate additional terminal position assurance (TPA) or secondary locking features beyond the primary terminal retention. Terminal retention relies on the terminal's own locking lance or feature engaging with the housing cavity.

Body Features – Natural Color Housing

The primary product color is Natural (uncolored/base Polyamide material). A natural housing provides:

Raw material traceability – easy to identify the base polymer type

No added pigments – reduces material cost

Aesthetic neutrality – suitable for applications where color coding is not required

Secondary processing ready – can be painted or labeled if needed

Mechanical Attachment

Mating alignment is provided (With) – this crucial feature ensures proper orientation when the receptacle is mated with its corresponding male header or plug. Mating alignment features such as polarizing ribs, slots, or chamfered corners physically prevent:

Reverse mating – inserting the connector backwards

Cross-mating – connecting to an incompatible connector type

Terminal damage – protecting contacts from misalignment during mating

Connector mounting type is Cable Mount (Free-Hanging) – the connector is not designed for panel or PCB mounting. Instead, it attaches to the end of a wire harness and hangs freely, plugging into a corresponding fixed connector on a device, panel, or another harness. This offers maximum flexibility for in-line connections.

Terminal Position Assurance (TPA) , Strain Relief, and Connector & Keying Code are not specified in the parameter table – the design relies on the terminal's primary locking feature for retention, and external strain relief may be added by the user if required for high-vibration applications.

Housing Features – Polyamide (Nylon) Material
The housing is manufactured from Polyamide (PA/Nylon) , a high-performance engineering thermoplastic widely used in automotive and industrial connectors. Polyamide offers:

Good mechanical strength and toughness – resists impact, cracking, and deformation

Excellent flexibility – less brittle than PBT, making it more resistant to housing damage during terminal insertion and connector mating

High heat resistance – maintains mechanical properties at 105°C maximum operating temperature

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

Wear resistance – maintains dimensional stability under repeated mating cycles

Cost-effective – provides excellent performance at a competitive price point

Natural color option – allows raw material traceability

The specific Polyamide grade (unfilled or modified) is optimized for the 9.14mm pitch design, providing adequate wall thickness between cavities for robust mechanical performance.

Centerline Pitch – Industry-Leading 9.14mm Spacing

The centerline (pitch) between adjacent contacts is an exceptionally wide 9.14 mm (0.359 in) . This is a distinguishing feature that sets this connector apart from standard 2.54mm, 4mm, 5mm, or 5.08mm pitch connectors.

Benefits of 9.14mm wide pitch:

Maximum electrical spacing – provides exceptional creepage and clearance distances, critical for:

Higher voltage applications within the 12V system (withstanding voltage spikes and transients)

Circuits requiring isolation between adjacent contacts

Applications with contamination or humidity concerns

Accommodates very large wire gauges – the wide spacing allows easy termination of thick wires (e.g., 8-12 AWG or larger) that would be impossible or difficult in tight-pitch connectors

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 for high-current applications

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

High-voltage safety margin – even though rated for 12V nominal, the wide pitch provides safety margin for voltage spikes or system faults

The 9.14mm pitch is approximately 3.6 times wider than standard 2.54mm signal connectors and nearly twice as wide as typical 5mm power connectors. This makes the RH7065-6.3-21 particularly suitable for applications where electrical separation is more important than compact size.

Dimensions – Compact Length

Product Length: 24.2 mm (0.952 in) – approximately 0.95 inches

Despite the exceptionally wide 9.14mm pitch between contacts, the overall connector length is a compact 24.2mm. This is achieved by optimizing the housing design – the 6 positions with 9.14mm pitch would theoretically span approximately 45.7mm from the center of the first contact to the center of the last (5 × 9.14mm = 45.7mm). The fact that the total product length is only 24.2mm indicates that the connector likely uses a staggered, compact, or multi-row configuration to achieve the 9.14mm effective pitch while maintaining a shorter overall length.

The connector height and width are not specified in the parameter table, suggesting the design prioritizes length and pitch specifications that are most relevant to the application.
