540204

Name: Festo 540204 Pressure sensor SDE3-D2D-B-FQ4-2P-M8
Brand: Festo

Pressure sensor SDE3-D2D-B-FQ4-2P-M8

The Festo 540204 is a piezoresistive industrial component featuring a dual relative pressure measurement range from 0 to 0.2 MPa (0 to 2 bar, 0 to 29 psi) with an overload pressure capacity of 0.6 MPa (6 bar, 87 psi). This unit incorporates a display, dual PNP switching outputs with freely programmable and switchable functions, and operates within a medium and ambient temperature range of 0 °C to 50 °C using compressed air conforming to ISO 8573-1:2010 [7:4:4]. It carries RCM, CE, and UKCA compliance marks, satisfies EU and UK EMC and RoHS directives, and features RoHS-compliant materials supporting lubricated operation.

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.
