Rotary encoder PP27

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

The AH36M rotary encoder with teach-in function is a magnetic absolute value encoder with analog output. The user himself can set the rotary encoder's desired measurement range via two external inputs. The device features a batteryless multi-turn technology. Absolute analog encoder. 12 Bit (4096) resoluttion over the measuring range. Operating tmperature until -40 °C. Voltage (0 … 10 V)/ current (4 … 20 mA) outputs. Programmable measuring range via teach-in function with external inputs. Hollow shaft with ø6 mm.

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
