Festo
537777
Diffuse light sensor SOEL-RTH-Q50-PA-K-3L
The Festo 537777 is an optoelectronic industrial component utilizing a diffuse reflection sensor with background suppression and pulsed red 650 nm laser light to measure position within a 50 to 300 mm working range. This block design sensor conforms to EN 60947-5-2, features copper- and PTFE-free materials, carries RCM and c UL us - Listed (OL) authorizations, and complies with the EU-EMV guideline. Operating on a 10 to 30 V DC voltage range, it delivers a PNP antivalent switch output with a maximum switching frequency of 2,500 Hz, a maximum output current of 200 mA, and pulsing short circuit strength.
