Small and flexible flat-ribbon cables are widely used by machine builders in LCD screens, as well as board-to-board connections for medical equipment, test and measurement devices and a whole range of industrial applications. In many of these, it is not important to have a vibration-free interlock for the plug-in connector, and for such applications, Würth Elektronik has now introduced what it refers to as a less expensive and easier-to-assemble solution to an LIF connector.
Fully suited for SMT pick-and-place assembly systems, the company’s WR-FPCs in 1-mm grid format are available in a variety of versions of between 4 and 30 pins, in both horizontal and vertical plug-in directions. Besides serving as sockets for flat flexible cables, they are also intended for use as connectors for flexible printed circuit boards – hence the designation FPC. The rated current is 1A, the operating voltage 125V. To ensure a high degree of elasticity with low wear and tear and a low resistance (30mΩ), Würth Elektronik has used phosphor bronze as the material for the contacts. The connectors have an undercoat of nickel to prevent the so-called ‘tin whisker’ phenomenon.
All are available ex-stock in component belts with no minimum order quantity, and free-of-charge samples can be supplied on request. Go to www.we-online.com for more information.
