RENISHAW ROTARY OPTICAL ENCODER
A range of rotary scales, including stainless steel rings and glass and stainless steel discs, are suitable for a wide variety of rotary motion applications. Rotary scale can be mounted to the rotating machine part by mechanical means or glue.
The rotary scales are compatible with Renishaw's open optical encoder series, for either absolute or incremental measurement.
Absolute encoders immediately decode their current position without any motion being required.
Incremental encoders can only detect motion relative to their current position or a known reference feature.
KEY FEATURES AND BENEFITS
1. High Accuracy and Resolution
Delivers sub-arcsecond precision, with resolutions up to 0.0001° (or higher).
Ideal for motion control systems requiring extreme angular accuracy, such as direct-drive rotary tables and high-speed spindles.
2. Non-Contact Measurement Technology
Most models use a non-contact readhead and rotary scale ring design (e.g., RESOLUTE, TONiC series), eliminating mechanical wear and backlash.
Ensures long-term reliability with minimal maintenance.
3. Compact and Flexible Installation
Available in various sizes — from miniature to large-diameter rings — suitable for space-constrained or complex rotary systems.
High installation tolerance allows for easier alignment and setup.
4. Strong Environmental Resistance
Excellent immunity to dust, oil contamination, and magnetic interference — ideal for demanding industrial environments.
