ZBI 2511 – Standard hydraulic cylinders (DIN 24333) – Nominal pressure 250 bar (25 MPa) Inductive sensing

Good to know: The STORZ ZBI 2511 hydraulic cylinder was developed as a supplement to the ZBD 2511 cylinder series. The hydraulic cylinders have integrated proximity switches to provide notification of the end position.

For the electrical monitoring of the piston end position, number of strokes or stroke sequence without any complex designs for the mounting external limit switches
Designed for a nominal pressure of 250 bar
Available in 5 mounting types and 6 sealing variants for a wide range of applications
Installation dimensions according to ISO 6022, DIN 24 333 and VW 39D921
Compact, non-contact proximity switches, pressure-resistant up to 500 bar
Electrical connection using plug connection
