539725

Name: Festo 539725 Sub-base VABS-S4-1S-G14-K2
Brand: Festo

Sub-base VABS-S4-1S-G14-K2

The Festo 539725 industrial component features a width of 26 mm based on the ISO 15407-2 norm and accommodates any mounting position with an external pilot air supply port. Operating pressure ranges from -0.09 MPa to 1 MPa (-0.9 bar to 10 bar) utilizing compressed air as per ISO 8573-1:2010 [7:4:4] where oil lubrication is possible and required for further use. Electrical specifications include a 24 V DC operating voltage range, 4 kV surge resistance, and a 2 A current rating at 40° C with a contamination level of 3. Compliance markings encompass CE, UKEX, and ATEX directives for Zone 2 gas environments under EPL Gc (GB) and II 3G categories with Ex ec IIC T3 Gc X ignition protection and an IIC explosion group, 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.
