Compact terminal block for pneumatic cylinders

With the new CBPS series, the Zimmer Group expands its portfolio with compact clamping and braking elements for pneumatic cylinders. The series enables the secure clamping, holding, and controlled braking of piston rods, providing a significant safety advantage for applications with vertical or moving loads.

Unlike conventional clamping elements, which are often designed solely for static holding tasks, the CBPS series features a true braking function. This allows movements to be reliably controlled and decelerated in the event of a pressure drop, machine stop, or malfunction, and loads to be held securely. The holding force is at least twice the force of the pneumatic cylinder used.

The elements, which can be mounted directly onto standard cylinders according to ISO 15552 and compact cylinders according to ISO 21287, impress with their compact design and standardized interfaces. This allows them to be integrated into new or existing machine concepts without significant design effort. Sensors for detecting the states "clamping open" and "clamping closed" further facilitate integration into the machine control system.

With a lifespan of five million static clamping cycles and up to 2,000 dynamic braking cycles, the CBPS series is suitable for demanding industrial applications. Thanks to safety certification according to DIN EN ISO 13849-1/-2, it is also designed for safety-critical applications.

The new CBPS series thus offers machine and plant builders a compact solution to increase process and machine safety, reliably prevent uncontrolled movements, and at the same time minimize space requirements and integration effort.

Product highlights at a glance:

– Compact design: no protruding contours in height and width, ideal for tight installation spaces.
– High clamping force at low pressure: operating pressure of 4.0 bar and a holding force of at least twice the force of the pneumatic cylinder.
– Long lifespan: designed for continuous industrial use with 5 million static and 2,000 dynamic cycles.
– Braking and holding: Declaration of conformity and certification according to DIN EN ISO 13849-1/-2 for maximum machine safety.
– Easy integration: standard piston rods or shafts with tolerances (f8/g8/h7), sensor detection "clamping open/closed" possible, interface for easy connection to pneumatic cylinders.
– Wide range of applications: suitable for typical industrial environments at temperatures between -10°C and +70°C, and protected against contamination thanks to integrated wiper.
