The JST 50PS-JMDSS-G-1-TF(LF)(SN) is a 50-position plug from the JMD series, designed as a board-to-board interconnect with outer shroud contacts. Gold contact finish and solder retention features target applications that see repeated mating cycles or vibration, such as portable electronics, industrial control modules, or test equipment where the connector stays mated through field service.
Pitch and Position Count — Fit for the BOM
At 50 positions across 2 rows, the connector body spans roughly 12.5 mm along the board edge, which is a standard footprint for high-density mezzanine links. The 50-circuit count must match the BOM line exactly; there is no 48- or 52-position variant in the JMD series at this pitch, so the position count is the binding constraint.
Right-Angle SMT and Solder Retention
For a 50-position connector, that retention is useful during reflow and subsequent assembly steps.
Gold Contact Finish and Mating Cycles
For the JMD series, the gold finish supports the connector's role in equipment that sees field service or test connections, where tin-plated contacts would wear or corrode over time.
