Description

 

The ultrasonic switch UPY 300 RA 24 is used instead of a conventional electric wall mounted switch when a non contact operation is necessary (e.g. sliding doors, lights etc.). This complies with certain hygienic demands (food processing industry, hospitals, clean rooms).

The advantage of ultrasonic sensors compared to optical switches is that they are least susceptible to dirt and fully water resistant. The sensor diaphragm is protected against mechanical wear by an orifice. The sensor reacts only to presence and not to movements. As soon as an object (e.g. a hand) is within the 30cm detection zone, the built-in relay switches. Since the sensor does sense the time of flight and not an intensity (as usual with optical sensors), it has a 100% background suppression. Loads of up to 30VAC/DC and 6A can be switched with the mono stable relay.

The UPY switch is offered as one unit together with the box cover (incl. sealing and 4 M3 screws). The box cover fits to a surface mount housing (APG) or to an in-wall mount housing (ELK) as well. For mounting into a wall one needs additionally a mounting plate (MPL).
