WT34-R220 SICK Standard photoelectric switch NEW

Product Description:

•Precise background suppression at long ranges

•Immune to ambient light and crosstalk from another sensor

•Switch selectable PNP or NPN output and light/dark switching

•Versions with DC voltage (10...30V) or universal AC/DC voltage (12 … 240 V DC / 24 … 240 V AC)

•Optional test input, adjustable ON and OFF time delays, alarm output

•M12 or terminal chamber connection: 90° rotatable

•UL approval

 

Benefits:

•Versions with IR LED provide precise object detection at sensing ranges of 2500 mm

•Immune to ambient light and crosstalk from another sensor, providing reliable operation and less downtime

•The sensor cover protects configuration components against environmental hazards

•Adjustable time delay, alarm output, test input, and universal AC/DC voltage provide additional flexibility and reduce the number of part numbers needed
