The locking ramp on each housing provides a positive mechanical latch when mated with an identical unit, which is the point of the non-gendered design: any two 556137-4 housings mate together, no need to track male vs female halves. The red polycarbonate (PC) insulation handles 0°C to 105°C, so it's suited for indoor industrial equipment, power distribution panels, and battery interconnect harnesses where you need a simple, keyed single-wire connection. ## Stackable — Gangs Into Multi-Way Assemblies Each 556137-4 is a standalone 1-position housing, but the series is designed stackable. That means you can snap multiple units side-by-side to build a multi-way connector block without a custom overmold. For a harness builder, this is the practical alternative to a fixed multi-position housing when the circuit count isn't known until the wire run is laid out. The locking ramp on each position still engages individually, so the stack holds together mechanically. Termination is crimp, so a standard crimp tool for the series is required.","metaTitle":"TE Connectivity 556137-4 AMPINNERGY 1-Pos Red Housing","metaDescription":"TE Connectivity AMPINNERGY 556137-4 1-position non-gendered housing, red polycarbonate, free-hanging, locking ramp.
