  • Description

    Displacement sensors models 8710 and 8711 with resistance tracks made of conductive plastic material are designed for a direct and accurate measuring of mechanical displacements. A special ball joint coupling is mountable on both ends of the driving rod. Because of this the sensor may be used free of clearance or lateral forces also with angular or parallel misalignment between sensor and measuring device.

    A special multi-fingered slider provides a good electrical contact also at high adjustment speeds or vibrations.

    Areas of application are:

    • Electromagnets
    • Switch and button deflections
    • Pneumatic cylinders
    • Press-fits (longitudinal press-fits)
    • Hydraulic cylinders
    • Measurements of deformation and bending
    • Length tolerances
    • Feeding paths

    Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system. Special processes are applied to give the resistance tracks low friction, low tendency to stick/slip, resistance to abrasion and long-term stability.

    The driving rods are guided in long-life, low-friction sliding bearings with close tolerances; this results in highly precise measurements. Lateral forces reduce the service life and can be avoided by using, for instance, ball joint couplings, included in the burster product range.

    Due to the pump effect, the driving rod has double sliding bearings.


    The sensor is mounted at the left and right longitudinal slot by four mounting angles.

    These slots (W = 2.2 mm, D = 1.6 mm) are closed at the side of the electrical connector.
