What This 4-Position 0.50 mm Pitch FPC Connector Does
Mating Cycles and Field-Service Reality
Rated for 20 mating cycles. For applications requiring frequent cable swaps — say monthly calibration cycles — the 20-cycle rating means the connector should be budgeted as a limited-life component. The slide-lock actuator adds a tactile confirmation of full engagement, reducing the chance of partial mates that accelerate wear.
The base product number is SFV4R; the full order code SFV4R-3STBE1HLF is the specific configuration with beige actuator and tapered cable end type.
The closest peer in the SFV-R series is the SFV4R-1STBE1HLF — same 4 positions, same 0.50 mm pitch, same gold plating, same 0.5 A rating. The difference is the cable end type: the -1 variant accepts both straight and tapered FPC ends, while the -3 variant is tapered-only. If your FPC has a straight end, the -1 is the correct pick; for a tapered end, either works.
