Festo
537778
Diffuse light sensor SOEL-RTH-Q50-NA-K-3L
The Festo 537778 is an industrial optoelectronic diffuse reflection sensor featuring background suppression and a block design that conforms to EN 60947-5-2. Operating within a 50 to 300 mm working range, this component utilizes a pulsed red 650 nm laser light with a maximum grey tone shift of 5 % on 18 % reference material and provides an antivalent NPN switch output operating at a maximum switching frequency of 2,500 Hz. Constructed from copper- and PTFE-free materials, the unit functions within an ambient temperature range of -20 to 45 °C and accepts a DC operating voltage from 10 to 30 V while delivering a maximum output current of 200 mA with pulsing short-circuit strength.
