SAR-ML700A
Single-Turn Absolute Encoder
Single-Turn Absolute Encoder
Model incorporating predictive maintenance function to minimize the risk of sudden failure-induced equipment shutdowns
Features
1. Predictive maintenance function
Incorporates a new predictive maintenance function using the compatible communication standard (A-format®)*. This allows early detection of potential failures and provides advance notification of the need for parts replacement and maintenance timing for industrial robots, helping to minimize the risk of sudden failure-induced equipment shutdowns.
- *A-format® is a registered trademark of Nikon Corporation.
2. Proprietary angle accuracy self-correction function
3. Product design incorporating interchangeability with existing models
Designed to be interchangeable with existing Nikon absolute encoders, it can be installed without design changes in mounting parts.
