540203

Name: Festo 540203 Pressure sensor SDE3-D2D-B-HQ4-2P-M8
Brand: Festo

Pressure sensor SDE3-D2D-B-HQ4-2P-M8

The Festo part number 540203 is an industrial component utilizing a piezoresistive pressure sensor with a display to measure 2 x relative pressure across a range of 0 to 0.2 MPa (0 to 2 bar, 0 to 29 psi) with an overload pressure of 0.6 MPa (6 bar, 87 psi). It features 2xPNP freely programmable and switchable switching outputs, operating with compressed air as per ISO 8573-1:2010 [7:4:4] within a medium and ambient temperature range of 0 °C to 50 °C. Certified with RCM compliance and c UL us recognition, this RoHS compliant unit adheres to EU and UK directives for EMC and RoHS.

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.

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.
