Name: Festo 3929370 Positioner CMSX-P-S-C-U-F1-S-50-A
Brand: Festo

Positioner CMSX-P-S-C-U-F1-S-50-A

The Festo 3929370 is a digital, electropneumatic positioner featuring a single-acting mode of operation and a safety position where pneumatic outlet 4 is exhausted. This component operates within a pressure range of 0.3 MPa to 0.8 MPa utilizing compressed air conforming to ISO 8573-1:2010 [7:4:4], and includes an integrated 7-segment backlit LCD display with onboard push-button configuration. Featuring a 24 V DC nominal operating voltage, 0-10 V and 0/4-20 mA analog inputs, and a G1/8 pneumatic connection, it supports a 0 to 100 degree sensing range via a linear potentiometer.

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.

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.
