542889

Name: Festo 542889 Pressure sensor SDE5-D10-C-Q4E-P-M8
Brand: Festo

Pressure sensor SDE5-D10-C-Q4E-P-M8

The Festo 542889 is a piezoresistive pressure sensor engineered to measure relative pressure across a range of 0 bar to 10 bar within a medium and ambient temperature of 0 °C to 50 °C. Operating on a DC voltage range of 15 V to 30 V, this RoHS-compliant component features a PNP switching output with a NC contact, a fixed hysteresis threshold value, short-circuit protection, and a max output current of 100 mA while supporting lubricated compressed air per ISO 8573-1:2010 [7:4:4]. It delivers a repetition accuracy of 0.3 %FS and a temperature coefficient of 0.05 %FS/K, backed by RCM, c UL us, CE, and UKCA conformity.

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.
