RSM-111-02-S-D-TR

The RSM-111-02-S-D-TR is a surface mount micro socket from Samtec's RSM series. It features a 22-position, double row design with a pitch of 1.27mm and row spacing of 2.54mm. The female socket contacts are made of phosphor bronze with tin plating, and the black liquid crystal polymer insulator is rated UL94 V-0 for flammability. Electrical ratings include a current of 3.8A per pin (when two pins are powered) or 3.1A per contact (general), and a voltage rating of 290 VAC. The operating temperature range spans -55°C to 125°C, making it suitable for demanding environments. This connector uses a push-pull fastening style and is terminated by soldering onto the PCB surface. The SMT design supports automated assembly, and the part is supplied in tape and reel packaging with 750 pieces per reel. The lead-free solderability is verified, and SMT lead coplanarity is controlled to 0.10mm maximum. Designed for board-to-board stacking applications, the RSM-111-02-S-D-TR mates with a variety of Samtec headers including the FTR, HTMS, HDWM, and DWM series. It is ideal for creating flexible, high-density interconnects in compact electronic devices.
