The 4.20mm pitch and 4.70mm row spacing give enough clearance for 20-24 AWG wire in a dual-row layout, and the locking ramp holds the mated pair together under vibration — a common requirement in appliance, HVAC, and industrial control panels.
The glow wire compliant rating (IEC 60695-2-11) means this housing can be specified in appliances and equipment that must pass a glow-wire ignition test, a common requirement for European market compliance. The locking ramp is a single-action latch that audibly clicks when fully mated, giving the assembly technician a positive confirmation of full engagement.
This plug housing accepts male crimp terminals from the Mini-Fit Sigma terminal family (order separately — contacts not included). The crimp termination is a standard 4-point indent crimp for 20-24 AWG wire.
