Position & level sensor compact - Gefran RK 2 & RK4

The Gefran RK series is a revolutionary new design which allows the sensor to be mounted entirely within the cylinder, or for other applications giving great flexibility in design. This is achieved by using extremely compact electronics and a very compact sensor  arrangement. The design allows use of cylinders with yokes - and this was not previously possible. The rod diameter is only 10mm and so there are few restrictions on the piston arrangement in smaller cylinders. Applications are not restricted to mounting in cylinders. These sensors can be used for displacement in many industrial situations - including liquid level with floats.

New versions include RK5  listed elsewhere which has slightly larger diameter electronics but shorter body length - and CanBus output.

  • Mounts entirely within the cylinder - can use with double YOKE rams
  • Thread mount version or clamp mount
  • Ranges from 50 to 4000m  sensor diameter 10mm
  • Digital and analog output versions
  • P67 protection - sensor from -30 to 90C
  • Max speed 10m/sec
  • Two models for 350 bar and 700 bar pressure rating
  • Independent linearity 0.02%

Note: Cursors and accessories such as cables must be ordered separately.
