RSM-118-02-L-S Description

Short technical summary and product information.

The Samtec RSM-118-02-L-S is a micro SMT board-to-board receptacle connector featuring 18 positions in a single row with a 1.27mm pitch. It is part of the RSM series, designed for low-profile, vertical stacking applications. The connector utilizes a dual-beam contact system made of phosphor bronze with a 10µin gold plating on the contact area and matte tin on the tails, ensuring reliable electrical performance. It is rated for 3.8A per pin (with 2 pins powered) and 290VAC, with an operating temperature range of -55°C to 125°C. The insulator is molded from black liquid crystal polymer (LCP) with a UL94 V-0 flammability rating. This receptacle is surface-mount and comes in tube packaging (25 pieces per tube). It mates with Samtec's FTR, HTMS, HDWM, DWM, TML, ZML, and TMS series headers. The contact finish thickness is 10µin (0.25µm) gold on the contact and tin on the tail. The connector orientation is vertical, and the fastening type is push-pull.
