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.

With the ever increasing automation of assembly lines, users are finding that values for absolute linearity are steadily gaining importance. Unlike independent linearity, for absolute linearity the reference slope is fully defined (Fig. 8) so that there is no need for subsequent system trimming. The definition of an index point establishes a relationship between the mechanical input value (travel or angle) and the output voltage. Potentiometers whose linearity is defined by these criteria can be installed without a need for subsequent adjustment. As with independent linearity, it is best to determine the absolute linearity of a potentiometer by comparing its output with that of a master potentiometer. With absolute linearity, it is frequently necessary for the tolerance fields to be stepped. Fig. 9 shows a practical example. Fig. 8 Fig. 9

Thanks to their small size – 21 mm square section case – the linear potentiometers seris PT2S can be profitably employed for those applications where limited dimensions are a critical factor. Two ball joints are provided at both ends for air fixing. The series strokes range from 25 to 150 mm. The electrical connection is granted by means of M12 connector. The stout extrused aluminium case grants a high protection degree against environmental agents.
