The tin plating (78.7 µin over phosphor bronze) suits moderate mating-cycle applications — think once-and-done or occasional rework, not daily disconnect. Housing is LCP glass-filled with UL94 V-0 flammability rating, actuator is glass-filled nylon.
Board-fit details: pitch, height, footprint
Mounted height above board is 2.56 mm (0.101"). That's low enough for tight stacking but leaves clearance for the FPC bend radius. The 1.00 mm pitch matches the standard FPC pad pitch — no special routing beyond the usual trace-width adjustment for 1 A.
Confirm the mating half (FPC with 0.30 mm thickness, 1.00 mm pitch, straight end) and the position count before committing.
