Rotary encoder TBA58/R2 redundant

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

Magnetic, absolute multi-turn rotary encoder WV36M/CAN - batteryless, with CANopen or SAE J1939 interface. Owing to its double ball bearing, small design and wear-free magnetic measurement method, the WV36M/CAN is also best suited for positioning jobs in mechanically demanding environments. Compact design (36.5mm diameter). CANopen (DS406) or SAE J1939 (DS417) interface. Multi-turn without battery. Double ball bearings. 12 bit multi-turn (4096 revolutions). 12 bit single-turn (4096 steps).

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.
