The single-row layout with friction-lock retention holds the mating header in place under light vibration but allows hand-tool unmating in the field, which matters for service loops on battery packs or display assemblies. ## Contacts Are Ordered Separately — Don't Skip This The housing ships without contacts — the note on this part is clear. You need to order the matching 503764-series crimp terminals (female socket, 1.00 mm pitch) to populate the 4 positions. The housing accepts the standard Pico-Lock crimp terminal, which is terminated to wire before insertion. If you're filling a BOM, add the terminal order code alongside this housing or the assembly won't mate. ## Mating Half and Wire Gauge This receptacle mates with the Pico-Lock 503764 series pin header — a 4-circuit, 1.00 mm pitch, single-row header with friction lock. The crimp terminals accept 26-30 AWG wire, typical for signal-level interconnects in tight-gauge harnesses.","metaTitle":"Molex Pico-Lock 5037640401, 4-Position Receptacle Housing","metaDescription":"Molex 5037640401 Pico-Lock receptacle housing, 4 circuits, 1.00 mm pitch, friction lock.
