Mating and Contact Details
This is a shrouded 4-wall header with a detent lock — mates with the corresponding Dynamic D-3100 receptacle housing (crimp terminals sold separately). The rectangular tab contacts accept the matching crimp terminal from the Dynamic D-3100 series. The detent lock provides audible feedback on full mate — no secondary TPA required on the header side.
The UL94 V-0 thermoplastic polyester housing meets the flame rating requirement for equipment-level safety standards. RoHS compliant per TE Connectivity's current declaration.
