Festo
537685
Retro-reflective sensor SOEG-RSP-M12-NS-K-2L
The Festo 537685 is a round industrial component utilizing an optoelectronic reflection light barrier measuring principle with red polarized light for position sensing within a 1500 mm working range. This device conforms to EN 60947-5-2 and operates on a 10 V to 36 V DC voltage range featuring an NPN dark-switching output, a maximum switching frequency of 1000 Hz, 200 mA max output current, and pulsed short-circuit protection. Certified with c UL us - Listed (OL) and the RCM compliance mark, it includes CE and UKCA markings per EU and UK EMC and RoHS directives while functioning within an ambient temperature range of -25 °C to 55 °C.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
