NKK Intros Contactless Pushbuttons
Contactless pushbutton switch.
Scottsdale, AZ — New from NKK Switches is the FP01 Series of contactless illuminated pushbutton switches. FP01 devices are suitable for critical and demanding applications requiring a robust and dependable solution.

The new switches use a diode photo interrupter rather than traditional contacts to ensure high reliability and a long life of 3 million mechanical operations minimum. These pushbuttons present an attractive alternative for engineers charged with designing panels for equipment that is exposed to corrosive gases and similarly harsh environments, where reliability due to contact contamination is a concern.

The rugged construction and smooth actuation of the FP01 Series allows repeated and rapid actuation force anywhere on the cap surface. Typical high usage applications for these devices include operator controlled industrial machinery, vending machines, gaming and museum displays.

The switches have super bright LED illumination with the LEDs as an integral component of the switch. Engineers can configure FP01 devices for highly visible status indication by choosing colored actuators to match the red, green or amber LED illumination, or for subdued illumination in low light environments by specifying a white actuator over the colored LED.

The switches use a single photo transistor that activates a momentary ON position. Mounting is with a snap-in mount for easy installation. Each device includes a six-pin socket and engineers can choose between assembled connector plugs with wire leads or unassembled plugs and pins.

The FP01 Series has a behind-panel depth of only 21.4mm (0.84-in.). Actuator caps are round with a diameter of 26mm (1.0-in.), providing ample actuating surface. The required panel cutout is 22.9mm (0.9-in.) and the recommended panel thickness range is 2.5 to 5mm (0.098 to 0.197). The operating temperature range is -25 to +50°C.

The actuator caps are constructed to easily accommodate pad printing or laser etching. Custom legends and additional value-added wire assemblies are available.
