ERS (for Holding and Emergency Stops / for Braking)
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.

Heat Dissipation Capacity
(allowable braking energy)
The heat dissipation capacity above indicates one of each discrete product. For clutch/brake unit (EPR type), regard 60% of the heat dissipation capacity in this graph as a standard.
