Frequently asked questions
What does the 770143-1 mate with?
The 770143-1 is the shrouded header half — it mates with the matching Universal MATE-N-LOK plug housing and individual crimp terminals (ordered separately) to complete the wire-to-board assembly. The locking ramp on the header engages the positive latch on the plug housing.
What is the current and voltage rating of the 770143-1?
12A per circuit at 600VAC. The per-contact rating assumes a single circuit carrying full current; thermal management of the housing sets the practical system limit when multiple circuits share a load path.
What is the pitch of the 770143-1?
0.250 inch (6.35 mm). The wider pitch compared to signal-density connectors gives the 770143-1 the current headroom needed for power distribution rather than signal switching.
