538311

Name: Festo 538311 Proximity sensor SIEF-M12NB-PS-S-L
Brand: Festo

Proximity sensor SIEF-M12NB-PS-S-L

The Festo 538311 is an inductive round industrial component featuring an 8 mm rated operating distance and a 6.48 mm assured operating distance with a PNP switching output and N.O. contact switching element function. It conforms to EN 60947-5-2, operates within a 10 V to 30 V DC voltage range at a max switching frequency of 2000 Hz, and functions across an ambient temperature range of -30 °C to 85 °C. This unit includes pulsed short-circuit protection, a 200 mA max output current, and reduction factors of 1.0 for aluminum, stainless steel St 18/8, copper, brass, and steel St 37, alongside RCM compliance, c UL us listing, and CE and UKCA markings.

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.
