Festo
537688
Diffuse scan SOEG-RTH-M18W-PS-K-2L
The Festo 537688 is a round optoelectronic industrial component utilizing a diffuse sensor with background suppression and red light to measure position within a working range of 10 mm to 120 mm. This EN 60947-5-2 compliant device features a PNP bright-switching output, a 500 Hz maximum switching frequency, 200 mA maximum output current, and operates on a 10 V to 36 V DC range across an ambient temperature of -25 °C to 55 °C. It includes pulsed short-circuit protection, reverse polarity protection for all electrical connections, and carries c UL us - Listed (OL) and RCM compliance marks alongside CE marking per the EU EMC directive.

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.
