High-quality optical and magnetic encoders from Renishaw

Production:: Renishaw plc (Graet Britain)

Encoders for position and motion control

Renishaw’s high-accuracy and high-quality encoders offer superior reliability, easy installation and are suitable for even the harshest environments.

An encoder is a sensor that detects position. An accurate scale (like a ruler or protractor) is read by an electronic readhead that converts position into a coded electrical signal. Encoders are available in a wide range of sizes and specifications. Renishaw has developed encoders that measure down to 1 nanometre – that is one billionth of a metre.

Industrial automation areas where Renishaw encoders are used: electronics, motion control, renewable energy, aerospace, semiconductor, solar PV, medical, robotics, print, scientific research, flat panel display, precision metrology, machine tools, coordinate measuring machines (CMMs).

Optical encoders

Open optical encoders

Open optical encoders

Open optical encoders provide robust and high-performance linear, rotary and partial arc position measurement. Renishaw incremental encoders are suitable for motion systems where immediate and accurate relative position is required. Renishaw’s absolute encoders offer functional immunity from power interruption.

Enclosed optical encoders

Enclosed optical encoders

Enclosed optical encoders offer an exceptionally robust design, ideal for harsh industrial environments such as machine tools. Renishaw proven absolute position measurement technology is robust and reliable. Non-contact design enhances repeatability and reduces wear. Superior sealing provides greater resistance to contamination by fluids and solid debris.

Magnetic encoders

Magnetic encoders

Magnetic encoders. Robust encoders for harsh environments

Magnetic encoders provide highly reliable linear and rotary position measurement. Their robustness allows incremental and absolute position measurement operation in harsh environments. Non-contact design ensures no mechanical wear during operation.
