The TE 770035-1 is a 4-position, single-row plug housing from the Universal MATE-N-LOK II series. The latch lock fastening provides a positive, vibration-resistant mate — a solid choice for harnesses in industrial control cabinets, automotive underhood, and appliance wiring where the connection sees movement or thermal cycling.
No pitch is listed on this housing — the pitch is defined by the contact position in the mating header or receptacle, not the housing itself.
Both are single-row, free-hanging, latch-lock housings that accept male or female contacts. The decision between them comes down to circuit count: 4 positions on the 770035-1 versus 6 on the 1-1376477-6. The 1-1376477-6 uses a glass-filled PA66 nylon with a 0.098" (2.50 mm) pitch, while the 770035-1 uses standard PA nylon and has no pitch listed.
