Festo
171166
Proximity sensor SMTO-8E-NS-S-LED-24
The Festo 171166 is an industrial component designed for T-slot mounting based on the EN 60947-5-2 norm, featuring a magneto-resistive measuring principle for position sensing with a 0.2 mm repetition accuracy. It provides an NPN switching output with a normally open contact function, operating at a maximum switching frequency of 130 Hz, a 100 mA maximum output current, and an ambient temperature range of -20 °C to 60 °C. The unit includes RCM compliance, CE and UKCA markings as per EU and UK EMC and RoHS directives, and RoHS-compliant materials.

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.
