Bearingless encoders - absolute and incremental

Durable and space-saving.

Baumer's bearingless encoders offer non-contact operation. Most are magnetic and all of them are virtually wear-free. Their reliable function is not affected by dust, dirt or humidity. They are extremely resistant to shocks and vibrations and have a virtually unlimited service life.

All Baumer bearingless encoders feature a very short design, so they are perfectly suited for use in cramped installation conditions and on direct drives.

Compared to other measuring methods, the magnetic measuring principle tolerates a wide air gap between the sensor and material measure. These encoders can thus operate reliably even during large shaft movements.

    Special features

    Baumer offers the largest selection of bearingless encoders, most of them with magnetic measuring principle.

    The product line ranges from the compact measuring system for small drive shafts that are Ø6 mm up to devices for generator shafts that are Ø740 mm or more.
