The latch lock provides positive retention against vibration without requiring secondary hardware.
The listing note is clear: Contacts Not Included. The housing accepts the standard AMPMODU MTE female crimp contacts, which are available in strip form for automated crimping or loose-piece for prototype builds.
Mating and fit
This is a female receptacle housing that mates with the AMPMODU MTE male header (through-hole or surface-mount, straight or right-angle). Single-row, 4-position — confirm your mating header has the same circuit count and row configuration.
