Festo
537689
Diffuse scan SOEG-RTH-M18-PS-S-2L
The Festo 537689 is an optoelectronic industrial component featuring a round design that conforms to EN 60947-5-2 with RCM and c UL us-Listed certifications alongside CE and UKCA markings per EMC and RoHS directives. This diffuse sensor with background suppression utilizes red light across a working range of 10 mm to 120 mm within an ambient temperature range of -25 °C to 55 °C. It provides a PNP switching output with light switching element function, a maximum switching frequency of 500 Hz, a 200 mA max output current, pulsed short-circuit protection, and operates on a DC voltage range of 10 V to 36 V with 20% residual ripple and 25 mA idle current.

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.
