Festo
549902
Air gap sensor SOPA-...
The Festo part number 549902 is an industrial pneumatic distance measuring component with a sensing range of 20 µm to 200 µm and a repetition accuracy of ±2.5 µm. Operating at a pressure of 4 bar to 7 bar with a supply pressure of 0.8 bar to 1.6 bar using compressed air per ISO 8573-1:2010 [7:4:4], it features switchable 2xNPN, 2xPNP, or PNP/NPN outputs alongside configurable analog outputs of 0-10 V, 4-20 mA, and 1-5 V. This RoHS compliant device carries RCM, c UL us, CE, UKCA, and KC-EMV certifications, and supports oil lubrication during operation within an ambient temperature range of 0 °C to 50 °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.
