Festo
537761
Retro-reflective sensor SOEL-RSP-Q20-NP-S-2L-TI
The Festo 537761 is an optoelectronic retro-reflective sensor featuring a block design that conforms to EN 60947-5-2 and carries RCM and c UL us - Listed (OL) authorizations alongside a CE symbol according to the EU-EMV guideline. Built with copper- and PTFE-free materials, this sensor utilizes polarized red light with a 1 mm max. spot diameter at a 300 mm sensing range to measure position across a 70 to 3,000 mm working range in ambient temperatures from -20 to 60 °C using a 51 x 51 mm laser reflector as reference material. It operates on a 10 to 30 V DC range with a switchable NPN switch output, 4,000 Hz max. switching frequency, 100 mA max. output current, <= 2.4 V voltage drop, and pulsing short circuit strength.
