The 350711-1 is a 6-position, 3-row, through-hole header from TE's Universal MATE-N-LOK series. It mates with the corresponding Universal MATE-N-LOK plug housing to make a board-to-cable/wire connection. Rated for general-purpose use, this header fits inside industrial controls, appliances, and power distribution boxes where the 6.35mm pitch gives each contact room to carry current without the temperature rise climbing through the housing ceiling.
This header accepts the Universal MATE-N-LOK plug housing (e.g., 1-480424-0 or similar 6-position plug). The 3-row layout with 0.250" row spacing keeps the pin field open enough for a soldering iron tip to reach every joint.
