Product details

Right-angle 4-position header with friction lock and board lock

12A at 250VAC — power handling in a compact single-row package

At 12A per circuit and 250VAC, this header can handle moderate power loads — think power supplies, control panels, or industrial equipment where a single-row harness feeds a board. The 5.08mm pitch gives enough clearance between contacts for this current level without excessive temperature rise.

Active production and RoHS compliance — no obsolescence risk

This header mates with a Commercial MATE-N-LOK receptacle housing (sold separately) using the friction lock for retention. The board lock provides additional mechanical hold during soldering and resists pull-out from cable strain.
