4.14mm Pitch Plug Housing — What You're Actually Ordering
The 794241-1: The natural nylon body carries a latch lock on each side for a positive mate in free-hanging (in-line) harness assemblies. Contacts are not included — you order the housing and the crimp terminals (male or female, depending on the circuit side) separately, which is the standard sourcing pattern for this series.
The Contacts-Not-Included Trap
The single most common mistake on this part is assuming the housing ships with contacts. It does not — the listing explicitly notes Contacts Not Included. You need to source the matching crimp terminals separately: TE offers both male and female contacts for the Mini-Universal MATE-N-LOK II series, and the housing accepts either gender. For a 4-circuit harness, that means ordering 4 terminals plus the housing. If you're filling a BOM line, confirm the terminal part number is on the same purchase order or you'll have a housing with nothing to stuff into it.
Latch Lock and Free-Hanging Fit
The latch lock on each side of the 794241-1 provides audible and tactile feedback when the plug is fully seated into the matching receptacle housing. For a free-hanging (in-line) connector, that latch is what keeps the pair mated under cable strain and vibration — no secondary locking mechanism required. The 2-row, 4-position layout gives you two circuits per row, which is a compact footprint for a 4-wire power or signal harness.
