The single-row layout with 5 positions means each cavity is independent; no shorting or daisy-chaining inside the housing.
Pitch and Position Count — What Drives the Fit
The 4.00 mm pitch is the key board-layout dimension if this housing feeds a PCB header — it sets the contact spacing on the mating header footprint. Five positions is a common count for a small power distribution point or a sensor/actuator interface where you need a few power and signal lines in one connector. The single-row format keeps the harness narrow, which helps when routing through a tight conduit or along a frame rail.
