Festo
553548
Proximity sensor SIEF-M18B-NS-K-L
The Festo 553548 is an M18 round industrial component featuring a 5 mm rated operating distance, an NPN switching output with an N.O. contact function, and a 3000 Hz max. DC switching frequency. Built with a 2.5 m TPE-U(PU) cable connection, this RoHS-compliant device operates within a 10 V to 30 V DC voltage range and a -30 °C to 70 °C ambient temperature span while conforming to EN 60947-5-2 standards. It includes pulsed short-circuit protection, reverse polarity protection for all electrical connections, and a max. output current of 200 mA alongside RCM, c UL us - Listed (OL), CE, and UKCA markings.

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.
