This header mates with MTA-156 receptacle housings and the corresponding crimp terminals. The 4-position, single-row layout is common for low-circuit-count power and signal interconnects in industrial control, general-purpose equipment, and appliance wiring.
The 3-644755-4 mates with MTA-156 receptacle housings that have a friction lock feature. The receptacle accepts the matching crimp terminals (tin or gold, depending on cycle-life requirements). Confirm the receptacle part number includes the lock ramp for a positive mate.
Yes, the 3-644755-4 is RoHS compliant, standard for the MTA-156 series.
