The ROBA topstop from Mayr is equipped with a standardized plug for easy connection and integration into sensorless monitoring systems.
Power transmission component provider Mayr showcased the new generation of its ROBA topstop safety brakes during November 2025’s Smart Product Solutions (SPS) in Nuremberg, Germany. The company said that gravity-loaded axes in robotics applications must be safe, and that its ROBA line makes this possible in smart environments.
The compatible ROBA brake-checker module enables permanent brake monitoring. And when combined with the ROBA gateway, Mayr said that the system delivers valuable data for proactive machine maintenance, a digital twin and smart production environments.
For production facilities or robots with gravity-loaded axes, Mayr said the protection of people and material is of the essence. Mayr said its ROBA topstop holds the loads in position reliably and prevents uncontrolled movements in case of power outages or emergency stops. Their placement between the motor and the output means that the brakes can be retrofitted in existing constructions, which reduces effort and costs.
For day-to-day industrial operations, the ROBA topstop braking system is equipped as an independent, compact module. Mayr said that the O-rings at the interfaces ensure reliable sealing against dust and moisture - the brakes achieve IP66 protection as standard. The vertical axes remain secured even when the drive is dismantled, which is advantageous during maintenance and transport.
With the ROBA brake-checker, Mayr said it offers a module that monitors the safety brakes without the need for additional sensors. It recognizes the brake’s condition based on current and voltage trends, enabling proactive maintenance.
Critical parameters - such as switching time, coil temperature and functional reserves - are reliably detected by the system.
And the additional ROBA gateway module makes the offering network-compatible so that collected data can be integrated into existing remote maintenance systems. Mayr said this also allows for the creation of digital twins, thus ensuring smart production and more transparency in the drive line.
