Magnetic absolute multi-turn rotary encoder in heavy-duty stainless-steel design – batteryless, robust and flexible. The WV42HD is predestined for demanding measuring jobs in the heavy-duty area owing to its extremely robust housing, its bearings, which are designed to tolerate high radial and axial loads as well as its high resistance against external impact. Heavy-duty design in stainless steel. Compact design (42 mm diameter). IP69K, IP68 protection category. Resistant to salt spray and acids. CANopen interface, SSI, analog. Multi-turn without battery. High shaft loadability of up to 270 N. 16 bit mult-iturn (65536 revolutions). 12 bit single-turn (4096 steps).

The encoders series MEM can be supplied in single or in multiturn version, with high resolution values: up to 13 bits info/revolution (corresponding to 8192 info/rev.) x 15 bits rev. (corresponding to 32768 rev.), in binary or Gray code. The multiturn encoders provide the SSI serial output signal, while the singleturn type offer two output options: SSI or push pull parallel signal. Several mechanical versions are available to satisfy all application requirements: round flange, square flange, hollow shaft, with different options for the shaft diameter and connection position and type.

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

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.
