Baumer has added a new offering to its portfolio of compact multiturn encoders for mobile machines. New non-contact encoder EB360R has been particularly designed for mobile machines and is free from maintenance even in harsh environments.
The encoder merges maximum performance with compact design for precise angle position and speed feedback, even where it's dirty, wet or hot. The EB360R will also endure vibration and shocks, making it ideal for use in construction vehicles, working platforms or agricultural machines.
EB360R bearingless magnetic encoder owes its robustness to the non-contact sensing principle comprising the sensor and a separate magnetic rotor. Angle position and number of revolutions are determined without any moving parts inside the sensor. The sensor is mechanically and thermally decoupled. Unlike conventional rotary encoders, there is no shaft leading inside. The sensing electronics of EB360R is fully encapsulated to prevent any ingress of liquids or dust. Such thoroughly encapsulated electronics in a corrosion-resistant plastic housing is another extra protection against shocks and vibration.
The Baumer team of developers has designed the EB360R particularly for use in severe harsh outdoor conditions. In the development of EB360R, Baumer strived to exploit to the utmost any option to cut the housing size down to a minimum - while maximizing robustness in parallel.
The requirements for the new encoder designed for mobile machines were ambitious and clear right from the start. From the developer's point of view, this has been a success. With a housing of just 22 mm in height when installed, the encoder in space-saving design provides maximum freedom in machine design.
However, most important for reliable continuous outdoor operation is long-term tightness. EB360R has passed conventional tests like IP67 and IP69K with ease. However, this does not say much about long-term tightness after many years of tough outdoor use. EB360R has proved fully reliable even after aggressive, simulated accelerated ageing in highly demanding tests, i.e. temperature shocks by immersion bath. The encoder will perform reliably even after being cyclically heated to 85 ºC and right away immersed in salt water of 0°C.
