Wire-actuated encoder SGH50

Position sensor for hydraulic cylinders with measuring lengths up to 5000 mm

open expert video
Absolute position sensor for hydraulic cylinders, telescopic cylinders, and piston accumulators, based on the tried and tested wire-actuated sensor technology. Durable, reliable, and robust. Developed with the know-how of over 30 years of experience in wire-actuated sensor technology. 

Profile SGH50:

  • Measuring range 0 … 5000 mm (196.85 inches)
  • Absolute measuring system
  • Pressure-resistant up to 350 bar, pressure peaks up to 450 bar
  • High degree of flexibility, adjustable to all measuring lengths thanks to teach-in 
  • Redundant interfaces available
  • Safety version usable up to Performace Level d
  • Analog, CANopen, SAE J1939, CANopen Safety interfaces
