JST JMD 20-Position Right-Angle Plug for Tight-Pitch FFC/FPC Interconnects
The 0.020" (0.50mm) pitch packs 20 circuits into a dual-row footprint — the kind of pitch that forces careful trace routing on the PCB but buys you a narrow connector body. It's a right-angle surface-mount plug with outer shroud contacts, meaning it wraps around the mating receptacle and the contacts face outward, which is typical for a plug that sits at the edge of a board and mates with a receptacle on a perpendicular daughtercard or flex circuit. The 0.189" (4.80mm) height above board sets the stack height budget when the mating receptacle is on the facing board. This is the plug half — the receptacle side (typically JMD series receptacles like the 20S-JMDSS-...) completes the pair.
This is the standard orientation for an edge-mounted plug that connects a daughtercard or flex circuit running parallel to the main board.
