Durable rotary position sensing

Novotechnik’s RSB-3600 and RMB-3600 single- and multi-turn Hall Effect rotary position sensors are available in a wide choice of configuration options for maximum application flexibility. Available from Variohm EuroSensor, the highly durable sensor range is housed in a tough 36.5 mm diameter all-metal housing with a choice of solid or hollow shafts and environmental protection from IP67 to IP69K. With an absolute 12-bit resolution and linearity of +/- 0.03%, output options include analogue current or voltage and incremental for the single-turn model, and analogue and high-speed SSI for the multi-turn. Aimed at demanding positioning tasks on industrial and agricultural machinery or mobile and marine equipment, the sensors are also available in dual-channel redundant versions.  

These rotary sensors utilise Novotechnik’s proven Novohall process. In single-turn applications, measurements are taken across the full 360°. The multi-turn model includes Novotechnik’s Giant Magnetoresistance (GMR-Effect) principle which is capable of gearless counting and storing revolutions during idle intervals. With no batteries the sensor can capture up to 16 revolutions as a “True-power-on“ system, it provides the measured value immediately upon start-up. The combination of Novohall and GMR-Effect can be applied to and is available in shaft-driven and touchless systems without mechanical shaft couplings. Long life and excellent durability even under the most arduous shock and vibration conditions are characteristics of these measurement technologies.

Variohm EuroSensor is a manufacturer, distributor and supply chain partner providing complete sales and application support across a comprehensive range of position, force, pressure, load, and temperature sensor technologies - for demanding measurement applications across industry, construction, agriculture, motorsports, research and more.
