2-position right-angle header for wire-to-board duty
The 1-770966-1 is a 2-position, single-row header from TE's Mini-Universal MATE-N-LOK series, designed for board-to-cable/wire applications. Its 0.163" (4.14mm) pitch is wider than many signal headers, so the PCB footprint is roomier and the current per circuit is less constrained by trace width.
Locking ramp and board lock keep the connection secure
The header uses a locking ramp that engages the matching receptacle latch — this gives a positive retention under vibration, unlike a friction-only fit. The board lock is a plastic peg that snaps into a hole on the PCB, holding the header in place during wave soldering so the pins stay aligned. The 4-wall shrouding protects the male pins from bending during handling and guides the receptacle into alignment.
Gold mating finish for repeated mate cycles
Gold on the mating interface handles repeated connect-disconnect cycles without oxidation; tin on the post is standard for solder joint reliability. The contact material is brass, a common choice for cost-effective signal duty.
