Unshrouded breakaway — snap to length or use as-is
For vibration-prone environments, pair this header with a receptacle that has a positive retention feature, or plan for a secondary mechanical lock in the assembly. The housing is black, glass-filled thermoplastic rated UL94 V-0.
Peer comparison: shrouded vs unshrouded for the same pitch
For a 12-position, 2.54 mm pitch, right-angle header with a friction lock and mounting flange, peer 1379030-3 is a brown, shrouded-4-wall header with tin mating finish and a 12 V voltage rating. It is a closer positional match but the tin finish and friction lock change the mating cycle life and retention profile — useful if the assembly needs a positive lock and can tolerate fewer mating cycles.
