LEMO B Series 7-Contact Fixed Receptacle

A 7-contact panel-mount fixed receptacle with a push-pull self-latching system that remains watertight even when unmated. The LEMO B Series 7-Contact Fixed Receptacle (part number HGC.0B.307.CLLP) provides secure, sealed connections for demanding environments.

Secure Push-Pull Self-Latching Connections

Mechanical vibration and accidental cable pulls can ruin a critical connection. This LEMO connector utilizes a push-pull self-latching mechanism to ensure the plug stays mated to the receptacle until intentionally released by the user. The 2 keys (alpha=90) alignment system prevents cross-mating in dense panels where multiple connectors sit side-by-side. Built with a chrome-plated brass shell and a nickel-plated brass latch sleeve, the housing resists wear during repeated mating cycles.

Watertight Integrity for Vacuum and Panel Mounts

Sealing matters when routing cables through bulkheads or custom enclosures. The HGC.0B shell style is designed as a fixed receptacle with nut fixing, offering IP68-equivalent watertight protection when unmated. This makes it highly suitable for vacuum-tight environments and panel mounting requiring watertight integrity. Operating across a massive -55°C to +250°C temperature range, the internal insulator material meets UL 94 / V-0/1.5 flammability standards for demanding installations.
