Würth Elektronik offers its “WR-FPC 1.00mm SMT ZIF Horizontal Back Locking Dual Contact” and “WR-FPC 0.50mm SMT LIF Horizontal Dual Contact”, which offer reliable retention for ribbon cables and flexible PCBs. These devices share a high level of protection against wear and loosening of the connection with their dual contact and securing points. The latter is of special interest for slender connectors utilised with 0.5mm pitch cables, which secures according to the LIF principle without locking – only with the spring tension of the contact.
WR-FPC 0.5mm LIF is offered in versions with 6 to 24 pins, WR-FPC 1.00mm ZIF with 4 to 22 pins. The locking mechanism on the back is a special feature of the space-saving ZIF connector. This is a popular solution, as there is no requirement to work with a lock on the cable side.
These connectors are targeted at automatic surface assembly. Further solder pads are offered to make the small LIF connector for 0.5mm pitch applications more mechanically secure on the PCB.
