Conductive plastic potentiometer - MCP40

As already indicated under Point 3, conformity is a more general concept than linearity. The definition of absolute conformity is similar to that of absolute linearity. It is essential for an index point to be defined. The functional relationship can either be determined mathematically to be defined. The functional relationship can either be determined mathematically or by plotting a number of points to establish a curve with the aid of suitable interpolation. It is also possible with a potentiometer to achieve steadily increasing or steadily decreasing functions such as logarithmic, exponential, sinusoidal or cosinal functions.

Through hollow shaft Ø 14 mm. Adaptation to various measurement distances owing to a wide range of gear ratios. Compact, low-cost design. Potentiometer or power output. Easy mounting.

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.

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.
