Product details

9-Pin 2.5mm Pitch Header for Wire-to-Board Harnesses

Rated 3A per contact at 250V, with tin-on-tin contact finish — adequate for signal and moderate power distribution in indoor equipment.

Locking Ramp and Shrouding for Field Reliability

For a service tech, this is the difference between a connector that stays mated and one that develops intermittent contact after a few months.

Note that this variant is marked RoHS non-compliant, so verify your assembly's regulatory requirements before adding it to the BOM line.
