540195

Name: Festo 540195 Pressure sensor SDE3-V1S-B-FQ4-2P-M8
Brand: Festo

Pressure sensor SDE3-V1S-B-FQ4-2P-M8

The Festo 540195 is a piezoresistive pressure sensor with an integrated display for measuring relative pressure across a range of 0 to -0.1 MPa (0 to -1 bar, 0 to -1.45 psi) with an overload pressure rating of 0.5 MPa (5 bar, 72.5 psi). This component features dual PNP switching outputs with freely programmable and switchable switching element functions, operating within a medium and ambient temperature range of 0 °C to 50 °C using compressed air as per ISO 8573-1:2010 [7:4:4]. It carries RCM compliance, CE marking per EU EMC and RoHS directives, UKCA marking, and is RoHS compliant regarding materials.

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.
