Name: Festo 4840802 Compact cylinder DPDM-20-20-PA
Brand: Festo

Compact cylinder DPDM-20-20-PA

The Festo 4840802 is a double-acting industrial component featuring a 20 mm piston diameter, a 20 mm stroke, and a profile barrel structural design with a piston rod at one end. Operating on compressed air per ISO 8573-1:2010 [7:4:4] within a 1 bar to 8 bar pressure range, this unit delivers a theoretical advancing force of 188 N and a retracting force of 158 N at 6 bar. It incorporates elastic cushioning rings at both ends, position sensing via proximity switch, and achieves ISO 14644-1 Class 6 cleanroom suitability with a CRC 2 moderate corrosion resistance rating.

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.
