Telescopic cylinders
Telescopic cylinders consist of several cylinder tubes pushed into each other and can thus generate more stroke than they are long.

ZTW 212 – Double-acting telescopic cylinder with displacement measuring system – Nominal pressure 120 bar (12 MPa)
Good to know: Here we have further developed the ZT 212 double-acting telescopic cylinder series in response to increased customer demand.
- standardized
- with a stroke length of up to 5000 mm, in 2- or 3- stage versions (available with more stages on request).
- integrated displacement transducer, completely enclosed, sealed off (IP69K)
- internally installed, pressure-resistant wire-actuated encoder for recording the displacement of the piston rod
- reliable, absolute encoding of the stroke at every stage
- for repeat accuracies of 0.2 mm.
- for analog values, CANopen and redundant measurement
- Plug connector as connection interface
