50-Position JST JMC Plug at 0.50mm Pitch
The JST 50PS-JMCS-G-1B-TF(N)(LF)(SN) is a 50-position plug from the JMC series, built with outer shroud contacts on a 0.020" (0.50mm) pitch in a dual-row arrangement. This is a fine-pitch, high-density interconnect — the 50 circuits pack into a board footprint that stays compact, making it a fit for space-constrained designs like handheld devices, camera modules, or internal display links.
Board Fit and Mounting
The right-angle SMT termination requires a reflow solder profile compatible with the gold-plated contacts. The 0.170" (4.33mm) height above board sets the z-axis clearance for the mating receptacle — check your enclosure height budget against this dimension. The 0.50mm pitch means the PCB footprint needs tight routing discipline — trace widths and spacing below 0.25mm are typical for the escape routing on inner layers.
The dual-row, 50-position layout is keyed by the shroud geometry — it is not compatible with other JST series like FM or GH, which use different pitch, contact spacing, and housing keying.
