Festo
538301
Proximity sensor SIEF-M18B-PS-S-L-WA
The Festo 538301 is an inductive round industrial component conforming to EN 60947-5-2 with RCM compliance, c UL us-Listed (OL) certification, and CE marking per the EU EMC directive. This PNP N/O contact sensor operates within a 10 V to 30 V DC voltage range, featuring a 5 mm rated operating distance, 4.05 mm assured operating distance, and unified reduction factors of 1.0 for aluminum, stainless steel St 18/8, copper, brass, and steel St 37. It achieves a maximum DC switching frequency of 2,500 Hz, 200 mA max output current, 0.1 mm repetition accuracy, and pulsed short-circuit protection across an ambient temperature range of -30 °C to 85 °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.
