The 20021311-00050T1LF is a shrouded vertical surface-mount board-to-board connector from the Minitek127® series designed for compact, high-density interconnections. It features a fine 1.27mm pitch with position ranges from 4 to 100, supporting multiple plating options including gold flash, 0.25µm gold, and 0.76µm gold for enhanced reliability and corrosion resistance. The connector operates at a maximum current rating of 1A per contact with an insulation resistance of 1000MO minimum and rated voltage of 125VAC, while maintaining durability through 100 mating cycles. Operating temperature range spans -55°C to +125°C, with mating and un-mating forces of 2.2N maximum and 0.2N minimum per contact. This connector is ideal for space-constrained applications in industrial robots, smart devices, servers, and storage systems where reliable board-to-board connections are critical.
