The sensors in the UM12 product family impress with their compact dimensions in a rugged metal housing. Two sensing ranges up to 350 mm and four available output signals – analog current or voltage output, PNP or NPN switching output – maximize flexibility even where installation space is limited. Color-independent detection, high contamination tolerance, and outstanding background suppression deliver stable measurement results even under challenging conditions. With the UM12 ultrasonic sensor in an M12 housing, SICK is now able to offer the proven technology for any application.

Detection, measurement or positioning of shiny and transparent materials
Level control for fluid or bulk materials
Diameter check for metal, paper, or plastic coils
Continuous detection of fabrics and wire grids
