Incremental encoder for smart monitoring

Developments in sensor and incremental encoder technology are helping engineers with new possibilities in drive technology along with expanding factory automation. The incremental encoders available from sensors specialist Baumer combine the benefits of low harmonics signal correction and wear-free design for precision, even under demanding conditions.

One of the options in its smart sensor range is the EB260 incremental encoder, a bearing-less rotary encoder, which combines the precision of optical sensing with the robustness of magnetic systems, while minimising installation space.

This encoder is designed to eliminate signal errors caused by mounting, temperature, ageing and mechanical factors, which results in maximum precision and enhanced control quality. The integrated airgap monitor continuously records the distance of the magnetic rotor, so the smallest changes caused by damage to the machine mechanics are monitored and reported to the higher-level system.

A feature is that the EB260 has a built-in IO-Link, which enables configuration flexibility. The software behind this is the Baumer Sensor Suite, a configurable motion monitor and switching output, as well as square-wave, sine/cosine and IOI-Link interfaces. Additionally, no shaft or a stator coupling is required so the need for a complex sealing or cover is eliminated due to the encapsulated suite software.

Further benefits include a compact space-saving integral design with simple installation into existing systems with flexible shaft diameters and mounting types, along with the need for only 11mm installation depth.

Typical applications for the EB260 encoder include speed control for asynchronous motors, precise incremental positioning, motion monitoring, overspeed, direction and standstill along with airgap, temperature, and signal quality control.
