Revolutionary magnetic detent mechanism delivers even more precise control

EBE sensors + motion has revised its handwheel HR100 for the precise machine control. Thanks to the innovative magnetic detent and new Hall sensor technology, the handwheel provides notable advantages over conventional models with ball-spring detent.

Production plants and industrial machines, such as CNC machines, are in constant use and must function; otherwise, production will halt. This is where the newly revised handwheel HR100 from EBE sensors + motion comes into its own. The handwheel with 100 detent positions based on Hall sensors promises an exceptionally long service life compared to conventional systems. While mechanical systems lose precision over time due to wear, the Hall sensors in the HR100 handwheel remain precise and reliable throughout their entire service life. The newly designed magnetic detent is also not subject to mechanical abrasion, increasing durability and reducing maintenance costs.

In contrast to optical or mechanical scanning systems, the use of the latest Hall- sensor-based scanning also guarantees consistently good input precision, even under difficult conditions such as vibration or shock. This is particularly advantageous in industrial environments where machines are often exposed to harsh environmental conditions. The noise immunity of the Hall technology also ensures consistently high accuracy and reliability in any situation.

Another unique feature is the intentionally integrated overrun. The detent mechanism allows sensitive adjustments to be made on CNC machines thanks to the 100 detents. In situations where a longer travel distance is needed for precise positioning, the overrun permits the operator to move the machine without cranking the entire distance. In contrast, a system with a ball-spring detent mechanism stops instantly in the detent position, even when turned quickly. This contributes to even more precise control and optimisation of the manufacturing process.

The HR100 handwheel is available in two versions to meet the user's needs. One variant is specially created for installation in control panels with selectable detent torque, where precise and reliable control is required directly at the machine interface. The other version has been optimised in terms of weight for use in manual control panels to ensure flexible and ergonomic handling, even in mobile applications. Of course, this variant can also be employed in thin stationary control panels. Both variants also provide the option of being expanded with various control knobs and scales made of sturdy light metal to permit additional adjustments and even greater operating precision.
