RH70416Y-1.8-21/174257-2

Detailed Product Description

The RH70416Y-1.8-21/174257-2 is a high-performance, sealable 4-position plastic housing connector designed for 12V automotive and industrial wire-to-wire applications. Engineered with precision and durability in mind, this rectangular connector housing is specifically intended for female terminals, making it an ideal choice for reliable electrical connections in harsh environments.

Product Type Features

This connector features a rectangular shape, which provides efficient space utilization and ease of handling during assembly. It is a non-mixed, non-hybrid connector, meaning all positions accept the same terminal type, simplifying inventory and assembly processes. As a housing for female terminals, it works seamlessly with corresponding male blade or tab contacts. The connector is fully sealable, offering excellent protection against moisture, dust, and other environmental contaminants. A primary locking feature on the terminal ensures secure terminal retention, preventing accidental disengagement due to vibration or thermal cycling. Designed as a wire-to-wire connector system, it terminates directly to wire and cable, making it versatile for various cabling scenarios.

Configuration Features

The housing provides 4 positions arranged in 2 rows, allowing for compact yet organized circuit routing. This dual-row configuration helps reduce the overall footprint while maintaining clear pin assignment.

Electrical Characteristics

With an operating voltage of 12 VDC and a nominal voltage architecture of 12V, this connector is perfectly suited for standard automotive electrical systems, including lighting, sensors, control modules, and auxiliary devices. It supports reliable power and signal transmission within the intended voltage range.

Body Features

The cable exit angle is 180° (straight), facilitating straightforward cable management and reducing bend stress on wires. The primary product color is black, which not only provides a professional appearance but also offers good resistance to UV degradation and thermal aging.

Contact Features

The housing accepts receptacle-type contacts with a contact size of 1.8mm. The mating tab width is precisely 1.8 mm (0.071 in), ensuring consistent and low-resistance electrical contact. This standard tab size is widely used in automotive connectors, making replacement and sourcing easy.

Mechanical Attachment

A mating alignment feature is included in the form of a polarizing slot, which prevents incorrect mating and ensures proper orientation during connection. This reduces assembly errors and improves production efficiency. Terminal position assurance (TPA) is not provided, so proper terminal crimping and insertion are essential. Strain relief is not integrated into the housing, meaning external cable management may be required for high-vibration applications. The connector uses cable mount (free-hanging) mounting type, offering flexibility for harness assembly without requiring panel or PCB mounting.

Housing Features

The housing is manufactured from Polybutylene Terephthalate (PBT) , a high-performance engineering thermoplastic known for its excellent dimensional stability, high heat resistance, low moisture absorption, and strong resistance to automotive fluids such as oil, fuel, and coolants. The centerline pitch (spacing between adjacent contacts) is 4.8 mm (0.189 in) , providing adequate creepage and clearance distances for 12V systems.

Usage Conditions

The operating temperature range spans from -30 °C to 105 °C (-22 °F to 221 °F) , with a maximum sustained operating temperature of 105 °C (221 °F) . This wide range makes the connector suitable for underhood, chassis, and cabin applications where thermal extremes are common.
