Board-to-Wire Connection for General Purpose Use
Its 0.156" (3.96 mm) pitch sets the PCB footprint and the mating receptacle requirement — a standard MTA-156 housing accepts it directly.
Tin-Plated Contacts and Mating Cycle Budget
For applications requiring frequent field-service disconnect or exposure to industrial atmospheres, a gold-plated sibling in the MTA-156 family would be more appropriate. The 1-wall shrouding provides basic polarization and protects the mating pins during handling, but does not fully enclose the contact area — a 4-wall shroud offers more protection against misalignment during blind mating.
No stock-holding claim is made.
MTA-156 Series Compatibility
This header mates with standard MTA-156 receptacle housings and accepts the corresponding crimp terminals (20-24 AWG typical). The 0.156" pitch and single-row layout are consistent across the series, making the 3-644611-2 a drop-in replacement for any 2-position MTA-156 header requirement.
