Name: Festo 538302 Proximity sensor SIEF-M18B-NS-S-L-WA
Brand: Festo

Proximity sensor SIEF-M18B-NS-S-L-WA

The Festo 538302 is a round inductive industrial component featuring a 5 mm rated operating distance and a 2500 Hz maximum DC switching frequency. Conforming to EN 60947-5-2 with RCM and c UL us-Listed certifications, this NPN normally open sensor operates within a 10 V to 30 V DC voltage range across ambient temperatures from -30 °C to 85 °C. It provides pulsed short-circuit protection, a 200 mA max output current, and identical reduction factors of 1.0 for aluminum, stainless steel St 18/8, copper, brass, and steel St 37.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
