M50-3121545 Description

Short technical summary and product information.

The M50-3121545 is a 30-position (15+15) female receptacle connector from Harwin's Archer M50 series. It features a 1.27mm (0.050") pitch and a dual-row layout for compact board-to-board or cable connections. Contacts are gold flash finished on copper alloy, and the housing is black high-temperature thermoplastic rated UL94 V-0.

This surface mount connector offers a push-pull fastening mechanism and supports mated stacking heights of 5.5mm and 6.18mm. The insulation height is 3.60mm, and the connector is terminated via solder. Electrical ratings include 1A current capacity, 20mΩ maximum initial contact resistance, and dielectric withstanding voltage of 300V AC.

The operating temperature range is -40°C to 105°C, making it suitable for demanding environments. Packaging is in tubes. RoHS3 and REACH compliance are claimed but unverified, while the UL flammability rating of V-0 is confirmed via datasheet.
