Product details

4-pin 2.5mm header for wire-to-board power

It mates with a crimp receptacle housing to make a wire-to-board connection rated 4.2A per contact at 250VAC. The 2.50mm pitch and shrouded 4-wall design keep the mating housing aligned and prevent accidental shorting across adjacent contacts.

Tin plating and friction lock for production environments

Compared to the 3-position sibling 1-2232960-3, this 4-position version adds one circuit while keeping the same 2.5mm pitch and tin plating — the extra position matters when your harness needs that fourth wire.
