The series MM10 without spring return / MMR10 with spring return is used in applications with very confined space, which require a miniaturized displacement sensor with long lifespan, high accuracy and guided push rod on both sides. The linear potentiometers of the series MM10 / MMR10 are especially space-saving designed and therefore very suitable for applications with very confined space. The potentiometric distance measurement is carried out with a high-resolution conductive plastic resistive element. Thanks to this Comolded conductive plastic technology and the high-quality sleeve bearings, the compact displacement encoder has a very long lifetime and high accuracy due to its good linearity. In the displacement sensor series MM(R)10 the mechanical detection of linear movement is done by a rear and front guided push rod. The displacement sensor can be used both as a probe and with a guided push rod. The internal or external spring return opens up additional applications.

If there is axial misalignment (eccentricity) between the drive shaft and the shaft of a potentiometer used to sense angular, motion, this will cause a linearity error that increases as the coupling radius decreases in relation to the degree of eccentricity. The following equation determines the maximum relative error Fmax = E/Pi · rk where E = Eccentricity und rk = the coupling radius. It is only possible to take full advantage of the linearity or conformity of any rotationary sensor system, if coupling alignment errors (offset and angular misalignment) are avoided or at least reduced to a mimimum. This means that with highly accurate measurement systems, due allowance must be made for any coupling misalingment in accordance with the above equation.

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.
