4-Position Micro Quadlok Receptacle Housing
The 2-967640-1: It's a free-hanging (in-line) housing designed for crimp termination — you bring your own female socket contacts, because this is just the shell. The gray PBT, glass-filled insulation handles the -40°C to 120°C range, which puts it in the engine-bay and industrial cabinet class.
What You're Actually Buying
This housing ships empty.
Four positions in two rows — that's a compact power or signal interconnect for a sensor, actuator, or small solenoid. The free-hanging in-line mount means it splices into a cable run, not onto a board. The PBT housing resists moisture absorption better than nylon, so it holds its dimensions in humid environments. The latch holder is the real tell: this housing is meant to stay mated under vibration, not for frequent plug/unplug cycles.
