The right
light curtain

for every task!


The Big Family – especially when it comes to measuring and switching!

Checking protrusions, heights or lengths, hole recognition, ejection monitoring and much more. A light curtain has a wide range of possible uses. Depending on the application, the machine control system may require a measurement value or just a hardware signal.

With our measuring CML light curtains and the switching CSL, CSR and Vario B devices, you can pick the right product for your application from a wide selection. And the CML and CSL devices use the same housing, thereby making the choice of operating principle independent of mounting and alignment.
