Safety brake with new friction system  

More torque, more emergency stops and increased safety. KEB Automation is expanding its product portfolio with the new COMBISTOP S1 spring-applied brake. The holding brake has a new, patented friction system. The advantage: a significantly higher braking torque, which corresponds to the level of permanent magnet brakes. As well as delivering higher performance, the S1 brake also requires less installation space, making it the first choice for numerous applications.  

In order to hold loads reliably at a standstill, high-quality holding brakes are required to ensure maximum safety during operation with emergency stop functions. With this in mind, KEB Automation has developed the COMBISTOP S1. The strengths of this innovative spring-applied brake are particularly evident in servo applications, as the increased safety requirements here are ideally met by the new brake.

“The COMBISTOP S1 is not only particularly temperature-resistant, but also offers high emergency stop friction energy and a stable torque in the range from minus 40 to plus 120˚ C. It therefore has properties that are advantageous in numerous applications,” says Matthias Kreinjobst, Head of the Brakes & Clutches business unit at KEB. 

In addition to servo motors, the COMBISTOP S1 is also used in medical technology, robotics and automation, industrial trucks and AGVs, electromobility and intralogistics. “The brake comes with a standard voltage of 24V, but customised voltages are also possible. A felt ring can also be integrated if required. This flexibility allows us to fulfil the individual requirements of machine and plant manufacturers,” adds Kreinjobst. Customised solutions are also possible regarding connector assemblies. 

The assembly of the COMBISTOP S1 also saves resources and costs as the series, which comprises a total of nine sizes, is designed as a plug-and-play system that enables the spring-applied brake to be installed quickly and easily. In addition, the pre-set air gap enables direct installation. The holding brake can then be constantly loaded, as it is designed for continuous operation (rated operating mode S1).
