MTMM-111-02-S-D-125

Headers, Male Pins Overview

The MTMM-111-02-S-D-125 is a board stacking connector from the Samtec MTMM series. It features 22 contacts arranged in two rows with a male pin configuration and straight installation style. The connector utilizes a 2 mm (0.079 inch) terminal pitch and through-hole solder termination. Constructed with phosphor bronze contacts and gold plating, it operates within a temperature range of -55°C to +125°C. The housing is made of black liquid crystal polymer (LCP) with a UL 94 V-0 flammability rating.

Headers, Male Pins Feature Summary
