The shrouded-1 wall and friction lock provide a secure mate with the matching MTA-100 receptacle, resisting vibration without a separate latch.
The 0.140" (3.56mm) post length clears most standard PCBs.
The UL94 V-0 thermoplastic housing adds a flame-retardant layer for equipment inside enclosures.
It mates with a matching MTA-100 receptacle (same series, 12-position, 0.100" pitch). The friction lock on the header engages the corresponding lock on the receptacle.
Yes, it is RoHS3 compliant.
A close alternative is 1-292164-1 from the CT series — also a single-row header, but with 11 positions and a 0.079" (2.00mm) pitch. It uses a detent lock instead of friction lock and is right-angle mount. Verify your position count and pitch before substituting.
