    Flexible, thin keypad controls access to enclosures

    Giving various users access to enclosures just got easier, thanks to a flexible, membrane keypad from Southco, Concordville, Pa. It holds up to 120 different user codes and can independently control keyless access to two enclosures. The keypad is made of a thin, flexible textured polyester film with switches and LEDs enclosed in it. Customers can specify any size, shape, or color keypad. Pressure-sensitive tape on the back of the membrane lets users stick the keypad to doors, frames, or any other flat surface.

    The keypad is powered by 12 to 24 Vdc and 10 mA. In standby, it draws only 30 μA. The keypad sends matrix outputs to an external controller.
