20-pin right-angle latch header for wire-to-board
The 1.80mm pitch sets the board footprint and the per-contact current ceiling — at 2A the temperature rise stays within the UL94 V-0 thermoplastic housing limit.
Pitch, circuit count, and current rating
Pitch: 1.80mm on the mating face, with 2.20mm row spacing. This is a fine-pitch layout — the board footprint needs precise routing, especially for the 20 circuits all loaded. Rated 2A per contact at 48V. The tin-plated mating finish (39.4µin) is suited for moderate mating cycle duty — not high-cycle field-service, but reliable for production harnesses that mate once and stay.
