Product details

0.156" pitch MTA-156 header with friction lock

It carries 9 positions (8 loaded) on a single row at 0.156" (3.96mm) pitch — the standard spacing for MTA-156 receptacles and crimp contacts. The shrouded single wall and friction lock keep the mating receptacle seated under vibration or cable tug, common in industrial control panels and general-purpose equipment.

Tin plating, wide temperature range

Both the mating contact and the post are tin-plated, which suits moderate mating-cycle applications (50-100 cycles) in clean, indoor environments.
