Capacitive Sensors

TURCK Inc. has announced QF 5.5, ultra-thin 5.5 mm (0.22") capacitive proximity sensors that can be mounted in very small areas and solve applications previously impossible. The sensors also have an extremely long sensing range relative to their size: either 5 mm or 10 mm flush mountable range, depending on model.

Exceptional mounting versatility is facilitated with several holes and slots in the sensors that allow multiple mounting options. The sensor comes standard with strap ties for use in mounting the sensor onto a sight glass or similar application. TURCK capacitive sensors reliably detect all metallic and non-metallic materials, including water, metal, wood, glass, cardboard, plastic, concrete block, glue, thin wire, silicon wafers, and numerous other materials. List prices begin at $75.00.

Especially significant, QF 5.5 sensors are available with or without a sensitivity potentiometer to adjust the range of the sensor. Models without potentiometer can be factory ordered with a preset sensing range anywhere between 2 mm and 10 mm. Highly visible, wraparound green and yellow LEDs are visible from three sides and indicate "POWER ON" and "OUTPUT ENERGIZED."

The 10-30 VDC sensors are embeddable in steel depending on sensitivity adjustment and are available with NPN (sourcing) or PNP (sinking), normally-open or normally-closed outputs.
