Baumer offers a series of rotary and angle encoders designed to determine the value of shaft rotation. Devices are capable of heavy duty operation in harsh conditions and explosive environments with temperature range (-30 to +100 °C, -22 to +212°F).

Rotary encoder is a sensor type providing linear and angular tracking of object movements with electronic signal output. Incremental rotary encoders have a zero coordinate point manually set. Absolute rotary encoders find a zero position automatically. There are optical and magnetic Baumer encoders. Optical sensors gather the position data via changes of the code wheel position tracked by photoreceiver. Magnetic sensors transform changes in magnetic fields generated by sensor magnets into position data output.

Based on purpose and design Baumer encoders comprise following groups:

Industrial incremental

Rotary encoder series featuring robust and compact incremental operating design.

Industrial absolute

Series of diverse rotary encoders designed to determine an object’s absolute position:

multi-turn
single-turn
magnetic
optical.

Heavy duty

This group consists of several type devices designed to perform in harsh conditions and aggressive environments:

Heavy duty incremental encoders
Heavy duty absolute encoders
Heavy duty sensors
Heavy duty tachogenerators.

Tachogenerators and resolvers

These are devices designed to measure the rotation angle

Tachognerators convert the speed (frequency) of the shaft mechanical rotation into an electrical output voltage signal
Resolvers are AC electrical transformers also capable of measuring the angle of rotation.

Special purpose

Baumer developed several sensor models intended to cover unusual technical requirements. When an industrial automation project has to be tailored to unique or sophisticated tasks, the company offers:

Bearingless sensors
Programmable encoders
Motor feedback encoders.

Accessories

The company produces a wide variety of accessories, parts and components for maintenance, repair and improvement of previously manufactured Baumer sensors.

Baumer encoders have gained world recognition as cutting edge technology, precise, reliable and dependable sensor devices.
