Häko Product configurator
This distinguishes our servo hydraulic actuators:
  • optimal price/performance ratio
  • suited for test tasks with long strokes
  • as single-rod or double-rod cylinders
  • with integrated position transducer
  • low dead weight
  • optional mounting plate for control valve

Sensor technology and valves for servo hydraulic actuators
Perfect for dynamic industry and test tasks

For the necessary sensitivity, Hänchen offers convenient sensor technology components and valves – all for highly dynamic, precise drives with high energy density.

Force transducer
Force transducers use strain-gauge or piezo-technology and measure the retracting and extending forces of the servo hydraulic actuator. They are installed directly on the piston rod and measure the load on the piston rod statically or dynamically. Force transducers are used e.g. for monitoring or controlling the cylinder force.
Load cell work on strain gauges or piezo technology and measure the tensile and compressive forces of the hydraulic cylinder
Valves
Control valves regulate the flow rate in proportion to the electrical select signal. Depending on the application case, valves with hydraulic pilot control or directly proportional solenoid-controlled valves are used. Valves with zero overlap of the control edges are especially suitable for hydraulic control tasks.
Proportional valves for Hänchen servoacturators
Proximity switch
Pressure-resistant inductive proximity switches detect the end positions of the stroke in the hydraulic servo actuator - wear-free and without contact. The signal is used to check or control the hydraulic cylinder. Servo hydraulic actuators with proximity switches also feature adjustable cushioning.
Pressure resistant inductive proximity switch detect the end positions of the stroke in the hydraulic cylinder contactless and wear-free.
Position transducers
Position transducers show the position of the piston rod electronically. An analogue or digital travel signal can be generated using the stroke. This can be used e.g. as an actual-signal in the position control circuit, or for monitoring position or speed limits. A position transducer can be integrated in the actuator, making a compact, mechanically protected servo hydraulic actuator system.
