These new flat pack devices allow power and signal coupling to be transferred across an air gap of up to 20mm. These wireless devices allow sensors to be connected to moveable platforms without the worry about twisting and rotating cables. Applications include rotating tables, moving pallets, modular tooling platforms and sliding fixtures.
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 conveniently side powered by 24 VDC.
