Festo
537720
Diffuse light sensor SOEG-RTH-Q30-PS-S-2L
The Festo part number 537720 is an optoelectronic diffuse reflection sensor featuring background suppression and a block design conforming to EN 60947-5-2. Operating within a 15 to 150 mm working range utilizing red light, this copper-free and PTFE-free component delivers a PNP switch output with a maximum switching frequency of 500 Hz and a 200 mA max output current across a 10 to 36 VDC operating voltage range. Carrying RCM and c UL us - Listed authorizations alongside a CE symbol according to the EU-EMV guideline, it functions within an ambient temperature range of -25 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.
