Festo
553544
Proximity sensor SIEF-M12B-NS-K-L
The Festo 553544 is a round M12 industrial component featuring a 3 mm rated operating distance, an NPN switching output with an N.O. contact function, and a 3-wire cable electrical connection with a 2.5 m TPE-U(PU) cable sheath. Conforming to EN 60947-5-2, this unit operates within a 10 V to 30 V DC voltage range, supports a max switching frequency of 3000 Hz at 200 mA, and functions in ambient temperatures from -30 °C to 70 °C with pulsed short-circuit protection and reverse polarity protection for all electrical connections. It carries RCM compliance, c UL us-Listed (OL) certification, CE and UKCA markings per relevant EMC, low voltage, and RoHS directives, and features 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.
