2. Verification Circuit

To ensure marking accuracy, Columbia Marking Tools' Random numbering heads come standard with a built-in verification circuit. This innovative air-pressure circuit allows the tooling to complete a cycle back to the "0" home position as frequently as required.

This feature provides dependable marking verification, ensuring precision and consistency across production runs. It’s an essential component for applications where accuracy and traceability are paramount.

3. Air control Module

The PLC serves as the primary communication hub for Columbia Marking Tools' Random numbering heads, ensuring seamless control and integration. Complementing this system, the Air Logic control module houses all the necessary air valves to manage the actuator's operation and, if required, the air impact marker.
