The latch lock provides positive retention against vibration without extra hardware. Typical applications include internal signal wiring in consumer electronics, small appliances, and low-current control harnesses where space is tight and a secure mate is needed.
Three positions in a single row keep the housing narrow, suited for low-circuit-count runs. Insulation is black PBT (polybutylene terephthalate), rated for continuous operation from -40°C to 70°C — adequate for indoor consumer and commercial equipment but not for high-temp automotive underhood environments.
No soldering or special tooling beyond a standard crimp tool is required for the wire side.
