Description

The SGH10 wire-actuated encoder measures the absolute direct cylinder stroke in a hydraulic cylinder. The new measuring system eliminates costly boring of the piston. As a result, integration costs are reduced compared to other measuring systems and a possible weakening of the piston is avoided effectively. The highlight of the SGH10L: Thanks to its unique lateral installation, the SGH10L can also be used in almost unsolvable applications, regardless of whether for applications in which no stoke lost can be accepted, extremely small piston diameters or in the case of cylinders with mechanical end position cushioning.

Measuring range 0 … 1000 mm (39.37 inches)
almost no stoke lost thanks to lateral mounting
Absolute measuring system
CANopen interface, analog: Current and voltage
Operating voltage 9 ... 32 VDC
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
High electro-magnetic compatibility
High shock and vibration resistance
With PURE.MOBILE technology
