Product details

Board-mount header for MTA-156 wire-to-board system

It mates with the standard MTA-156 receptacle housing, creating a reliable wire-to-board interconnect for general-purpose and industrial equipment. With 17 position cavities but only 13 positions loaded, this header accommodates selective population for harness configurations where not every circuit is needed.

The single-row, 3.96mm pitch layout gives you a compact but serviceable footprint — each contact is spaced wide enough for easy routing of 18-24 AWG wire in the mating receptacle. The 600VAC rating is higher than typical for this pitch class, so this header can handle line-voltage distribution within an enclosure as long as the creepage distances are respected.

RoHS compliant, housed in a UL94 V-0 rated thermoplastic, and available in bulk packaging.
