Name: Festo 546401 Round cylinder DSNU-3/8"-3"-P-A
Brand: Festo

Round cylinder DSNU-3/8"-3"-P-A

The Festo 546401 is a double-acting industrial component built on the ISO 6432 norm featuring a 3/8-inch piston diameter and a 3-inch stroke with an external 6-32 UNC-2A piston rod thread at one end. Operating between 1 bar and 10 bar using compressed air as per ISO 8573-1:2010 [7:4:4], this unit provides elastic cushioning rings at both ends, position sensing via proximity switch, and an ambient temperature range of -4 °F to 176 °F. It delivers a theoretical force of 10.6 lbf advancing and 8.9 lbf retracting at 6 bar while maintaining moderate corrosion resistance class 2 and VDMA24364-B1/B2-L LABS conformity.

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.
