Integrated sensor groove
Clamping and braking elements get a new inner life
Zimmer is adding a new feature to its RBPS series with the RBPS-A series of clamping and braking elements. A sensor groove enables retrofitting with magnetic field sensors.
The magnetic field sensor, including the two-point sensor without additional interfering contour, is recessed in the sensing groove without affecting the installation space and the sensor line can be routed together with the pneumatic line, which reduces the installation effort. Both piston positions can even be queried via the two-point sensor.
The RBPS series is designed for use on round guide rails and is mainly used in gantries, for example to prevent tools and gripping devices from falling in the event of a drive failure, brake failure, belt breakage or axle breakage.
The manufacturer points out the low opening pressure of four bar and the response time of less than 30 milliseconds. The Zimmer element positions with virtually no play. After braking or clamping, work can continue in both directions without the need for a reset movement first. The new RBPS-As extend the possible uses of the safety clamping elements by optionally monitoring the open/closed state and also shorten the cycle times of the application.
While the size range of the predecessor model RBPS previously extended up to shaft diameters of 45 millimetres, the RBPS-A series now offers three new sizes for round shafts with diameters of 50, 55 and 60 millimetres. The new sizes have a uniform outer diameter and achieve holding forces of 52 kilonewtons thanks to double pistons and power transmission via the wedge gear. as
