Name: Festo 541066 Sub-base VABS-S4-1S-N14-B-K2
Brand: Festo

Sub-base VABS-S4-1S-N14-B-K2

The Festo 541066 is an industrial component featuring a width of 26 mm conforming to ISO 15407-2 and supporting any mounting position with internal pilot air supply. It operates within a pressure range of -0.09 MPa to 1 MPa (-0.9 bar to 10 bar) and a 24 V DC operating voltage range, incorporating a surge resistance of 4 kV, a current rating of 2 A at 40° C, and a contamination level of 3. This unit includes CE, UKCA, and EPL Gc (GB) explosion protection certifications for Zone 2 ATEX and UKEX environments with II 3G gas ignition protection of Ex ec IIC T3 Gc X in explosion group IIC. The component utilizes compressed air per ISO 8573-1:2010 [7:4:4] where oil lubrication is possible and required for further use, maintaining a corrosion resistance class of CRC 0 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.
