The 55510-050LF is a 50-position, 2-row board-to-board receptacle from the Minitek® 2.00mm series. All 50 positions are loaded, so the BOM circuit count is exactly what the part number says. The 1.97 µinch gold plating on the mating face provides moderate corrosion protection and a few hundred mating cycles — adequate for production assembly and infrequent field service, not for daily reconnect duty. Surface-mount termination with a push-pull fastening system means the connector self-aligns during reflow and releases without a latch tool. The 4.50 mm insulation height gives clearance for trace routing under the body on dense boards.
Thermal and Flammability Rating for Enclosed Equipment
Operating temperature spans -55°C to 125°C, covering most industrial cabinet and medical device thermal profiles without derating concerns at the connector level.
