Inductive coupling devices

Pepperl+Fuchs has introduced flat-pack style transmitter coupling devices to its WIS (short range wireless inductive coupling system) product family. The new flat pack devices allow power and signal coupling to be transferred across an air gap of up to 20 mm. These wireless devices allow sensors to be connected to moveable platforms without the worry of twisting and rotating cables. The WIS transfers both power and signal without the use of batteries, by using two transmission elements that allow transfer when they come within the required proximity range. The WIS system can interface to eight PNP sensors via a single interface block. Multiple secondary modules can be connected to a single primary, whether they’re being used for inductive, capacitive, ultrasonic or photoelectric sensing. They are side powered by 24 VDC.
