Festo
537728
Diffuse light sensor SOEL-RTH-Q20-NP-S-2L-TI
The Festo 537728 is an industrial optoelectronic diffuse reflection sensor featuring background suppression, a block design, and a red laser light source with a maximum spot diameter of 0.7 mm in focus. Complying with EN 60947-5-2 and the EU-EMV guideline, this copper- and PTFE-free component operates within a 30 to 110 mm working range and a -20 to 60 °C ambient temperature range while utilizing an NPN switch output with a maximum switching frequency of 1,000 Hz. Authorized by the RCM Mark and c UL us - Listed (OL), the unit provides a max output current of 100 mA, pulsing short circuit strength, and a maximum grey tone shift of 7 % based on 18 % reference material.
