Product details

24-position dual-row header at 0.100" pitch

The 280521-1: The shrouded 3-wall housing protects the square male pins during handling and mating, and the detent lock provides a positive hold against vibration — useful in equipment racks or control panels where the connector sees occasional shock.

3 A per contact with tin plating

Rated 3 A per contact at 40 V, with tin-on-tin mating surfaces — 118.1 µinch (3.00 µm) of tin on both the contact and the post. Tin is a cost-effective choice for moderate-cycle applications (50–100 mates) in clean, indoor environments. The 3 A ceiling keeps the temperature rise within the UL94 V-0 thermoplastic housing's limits across the -40°C to 80°C operating range.

Mates with AMPMODU Mod II receptacles

The 0.260" (6.60 mm) mating pin length provides good wipe and contact engagement. For a wire-to-board application, pair it with a 24-position dual-row receptacle housing and matching crimp terminals — the detent lock on the header engages with the receptacle latch.
