Name: Festo 8097421 Positioner CMSH-S-VDE1-D-A-AL-N14-C1N12-HA
Brand: Festo

Positioner CMSH-S-VDE1-D-A-AL-N14-C1N12-HA

The Festo 8097421 is a digital, electropneumatic positioner featuring a double-acting mode of operation, an integrated linear potentiometer with a 0 deg to 115 deg sensing range, and an LCD display rotatable via software by 90°. It operates within a pressure range of 0.14 MPa to 0.8 MPa (1.4 bar to 8 bar) utilizing compressed air as per ISO 8573-1:2010 [7:4:4], delivering an air performance of 270 l/min at Δp = 6 bar through a 1/4 NPT pneumatic connection. Settings are configured via the display and keys, supporting 4–20 mA analog inputs with HART and reverse polarity protection.

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.
