Festo
552144
Air gap sensor SOPA-CM3H-R1-WQ6-2N-M12
The Festo part number 552144 is an industrial component utilizing a pneumatic measuring principle to detect distance within a sensing range of 20 µm to 200 µm at an operating pressure of 4 bar to 7 bar. Powered by a DC operating voltage range of 22.8 V to 26.4 V, this unit features a 2xNPN switching output with window comparator and threshold value functions, delivering a repetition accuracy of ± 2.5 µm and a maximum output current of 100 mA. It operates with compressed air as per ISO 8573-1:2010 [7:4:4] under ambient temperatures from 0 °C to 50 °C and carries c UL us - recognized (OL), RCM, KC-EMV, CE, and UKCA markings alongside RoHS compliance.

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.
