Features
- Operates immediately at power off.
- Realized high speed response by permanent magnetic force.
- Completely non-contact when brake is released. No wear, noise and vibration is generated when rotating.
ERS-L (for Holding and Emergency Stops)
- Backlash-less by plate spring driving.
- Flexible mounting directions.
ERS-A(for Braking)
- With automatic gap function, there is no need of adjustment after installation.
- Heavy-duty operation is possible by high heat radiation capability.
