Festo
151685
Proximity sensor SMTO-1-PS-S-LED-24-C
The Festo 151685 is a block-design industrial component utilizing a magneto-inductive measuring principle to monitor position within an ambient temperature range of -25 °C to 70 °C. Built on the EN 60947-5-2 norm with RoHS-compliant materials, it features a PNP switching output with a normally open contact function, a maximum switching frequency of 1 kHz, and a repetition accuracy of 0.2 mm. This unit carries RCM, CE, and UKCA compliance markings, incorporates an inductive protective circuit adapted to MZ, MY, and ME coils, and delivers a max output current of 200 mA with a 1 ms on and off time.

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.
