Name: Festo 539723 Sub-base VABS-S4-2S-G18-K2
Brand: Festo

Sub-base VABS-S4-2S-G18-K2

The Festo part number 539723 is an industrial component featuring an 18 mm width built on the ISO 15407-2 norm with any mounting position and external pilot air supply port. Operating at a 24 V DC operating voltage range with a 2 A current rating at 40° C, 4 kV surge resistance, and contamination level 3, it handles an operating pressure of -0.09 MPa to 1 MPa (-0.9 bar to 10 bar) using compressed air as per ISO 8573-1:2010 [7:4:4] with oil lubrication possible and required for further use. This unit includes a corrosion resistance class (CRC) of 0, LABS conformity to VDMA24364-B1/B2-L, CE and UKCA markings per EU and UK directives for ATEX Zone 2 gas explosion protection with EPL Gc (GB) certification, ATEX category II 3G, and Ex ec IIC T3 Gc X ignition protection for explosion group IIC.

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.
