5-position MTA-156 right-angle header with friction lock
The 0.156" (3.96mm) pitch sets the PCB footprint — it's wider than 2.54mm pitch headers, so it accommodates larger wire gauges and carries higher current per contact. The friction lock fastening type holds the header to the mating receptacle without a separate latch — it's a simple, positive retention that resists vibration in industrial equipment. The single-wall shrouding protects the pins during handling but leaves the mating face partially exposed, so the header is keyed by the housing geometry, not a full shroud.
Tin-plated contacts and UL94 V-0 housing
Tin is a cost-effective choice for applications with infrequent mating cycles — it's rated for a few dozen cycles before wear-through, which is fine for a harness that's assembled once and only disconnected during service. The copper alloy base material provides good conductivity and spring properties. The housing is glass-filled thermoplastic rated UL94 V-0, the highest flame-retardant class for plastic enclosures.
