Rectangular Connectors

Rectangular connectors are widely used in industrial, automotive, aerospace, and military applications where reliable transmission of power, control signals, and data is required. Their rugged construction and high contact density make them suitable for environments exposed to vibration, shock, and demanding operating conditions. RSP Supply carries a full line of rectangular connectors and modular components designed to support flexible, high-performance electrical interconnections.

To enhance adaptability and system customization, rectangular connector systems are available with a variety of accessories, including adapters, contact inserts, modular contact inserts, and dummy modules. Contact inserts define the electrical interface of the connector, allowing users to select specific contact layouts for power, signal, or data transmission. Modular contact inserts provide additional flexibility by allowing multiple insert types to be combined within a single connector housing, supporting mixed-signal applications in compact spaces.

Adapters are used to interface different connector types or configurations, simplifying integration with existing equipment or cabling systems. Dummy modules are non-conductive inserts used to block unused connector positions, helping maintain mechanical stability, environmental sealing, and proper alignment. Together, these components allow rectangular connectors to be configured for a wide range of applications while maintaining durability, long service life, and secure mating through latches, levers, or jackscrews.
