Zimmer CSR Crash Protection Review: Specs, Price and Applications

The Zimmer Group CSR series is a crash protection device mounted between the robot flange and the tool. Its triggering sensitivity is set by air pressure, and an integrated sensor signals the controller to trigger an emergency stop when a collision occurs.
After a crash the CSR is returned manually rather than automatically. Zimmer designed it this way so that an operator inspects the machine and identifies the cause of the stop before restarting.
Quick Verdict
A reliable collision protector for cells where every crash should be investigated. Pressure-adjustable sensitivity adapts it to different tool weights.

Design and Operating Principle
The CSR uses compressed air to preload the tool side against the robot side. When a force or torque exceeds the preload, the unit deflects and the sensor switches. Deflection gives the robot time to brake, protecting expensive grippers and the robot itself.
Pressure-adjustable sensitivity is practical: lighter tools need less preload, heavy tools and high accelerations need more to avoid false triggers.
Manual return ensures that nobody restarts a crashed cell without checking tool alignment, fingers and the part, reducing the risk of repeated collisions.
Integration and Selection
Set the pressure to avoid nuisance trips during normal motion while triggering well below damage thresholds. Wire the sensor into the robot's stop circuit and test at production speed.
Document the manual reset procedure for operators.

Who Should Consider the Zimmer CSR Crash Protection?
The CSR suits cells where operators must check the cause of each collision before restarting.
Price and Availability
Price: Request a quote. Zimmer Group prices the CSR by size, options and quantity, so the final figure depends on the exact configuration. Budget for the complete tooling package, including fingers or adapters, mounting, air or electrical connections and commissioning time, rather than the module alone.
