Need an encoder for a position and motion control system? Discover how our different types of encoder products can meet your industrial automation needs. Renishaw's high-accuracy and high-quality encoders offer superior reliability, easy installation and are suitable for even the harshest environments.
Open optical encoders provide robust and high-performance linear, rotary and partial arc position measurement. Our 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 offer an exceptionally robust design, ideal for harsh industrial environments such as machine tools. Our 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.
Laser encoders provide linear position measurement with high resolution and low cyclic error (SDE). They combine the measurement performance of a displacement interferometer with the ease of use and installation of traditional tape or glass scale encoders.
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.
Which areas of industrial automation use encoders?
We supply encoders to a wide range of industries and applications, including:
- scientific research
- machine tools
- motion control
- flat panel display
- co-ordinate measuring machines (CMMs)
- renewable energy
- solar PV
- precision metrology
Renishaw encoders feature a zero-wear non-contact design. We offer incremental and absolute scales in a variety of materials. Our readheads provide position signals with low electrical noise and high resistance to vibration.
