The 644875-4: Right-angle through-hole termination places the header parallel to the PCB, keeping the mated wire assembly low-profile for board-edge routing in tight enclosures. The friction lock on the shroud provides a positive detent with the mating MTA-100 receptacle — enough retention for moderate vibration but not a secondary latch like a TPA.
Sourced through independent distribution against RFQ.
It mates with MTA-100 single-row receptacle housings and the corresponding 22-26 AWG crimp terminals. The friction lock engages with the matching slot on the receptacle shroud.
