The 4-1734592-0: At 0.020" (0.50mm) pitch, this 40-position FPC connector demands a tight board layout — the trace routing between pads leaves little room for via fan-out under the connector body. The bottom-contact design means the FPC sits flush against the PCB, keeping the stack height at 0.081" (2.05mm) above the board, which matters when the connector lives near a cover or another board in a mezzanine stack.
ZIF and slide lock — assembly and retention
Zero insertion force (ZIF) with a slide lock actuator means the FPC slides in without bending the contacts, then the lock pushes the pressure bar down to clamp the cable. The slide lock holds the FPC against vibration better than a simple flip-lock — good for equipment that sees occasional shock or transport. The tapered cable end type helps guide the FPC into the slot without stubbing.
