The MP20/21 potentiometer series is ideal for applications in which a highly precise, durable and compact sensor is required. The conductive plastic potentiometer MP20/21 (MP21 with mechanical end stops) is an all-around performer that can be adapted for a variety of applications. The radial gold-plated soldering lugs ensure a low housing depth and are suitable for flat connectors (2.8 mm to DIN 46247 part 3). In addition, the high accuracy and lifespan of the sensors are sure to impress, thanks to the high-quality Comolded-Conductive plastic technology. * - Long lifespan and high accuracy * - With or without mechanical end stop (320° / 360°) * - Optional tandem version

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

These displacement sensors are potentiometric displacement sensors used for direct measurement, testing and monitoring of mechanical displacements. The spring-loaded control rod eliminates the need of coupling with the measurement object. A prerequisite for a very long life duration of the devices is a parallel alignment of the motion direction of the measurement object and the rod. Areas of application are: Displacement on: —Electromagnets —Hydraulic cylinders —Switches and buttons Measurements of: —Deformation —Bending —Press-fits —Feed strokes Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system. FEATURES: —Measurement ranges: 0 ... 10 mm to 0 ... 150 mm —Non-linearity up to 0.05 % F.S. —Resolution 0.01 mm —Follower roll on request —Optional with internal spring

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.
