0.156" pitch, 8 positions, friction lock — the MTA-156 workhorse
The 0.156" (3.96mm) pitch sets the board footprint and the per-contact current ceiling — at this pitch the header can handle up to 600VAC, making it suitable for industrial control panels and power distribution inside equipment enclosures. The through-hole solder termination keeps the header mechanically anchored to the PCB during assembly.
600VAC rating and UL94 V-0 housing — compliance for industrial panels
Rated 600VAC, this header can carry line voltage in IEC and UL equipment without derating in most cabinets. The UL94 V-0 housing ensures the connector does not propagate a flame in the event of a fault — a standard requirement for power supplies, PLCs, and motor drives.
Mating half and termination — what connects to 640388-8
This header mates with MTA-156 receptacle housings that accept 20-24 AWG crimp terminals.
