Quick Answer:
Short Answer
Yes. The SCU5 and SCU6x controllers process two sensors with independent enable/disable control for bidirectional coating applications.
Yes. The SCU5 and SCU6x controllers can process two sensors simultaneously with independent enable/disable control. This is ideal for bidirectional coating machines that run forward and backward between passes.
Typical dual-sensor configuration:
- Sensor 1: Mounted on the rewind moving frame—enabled during forward winding
- Sensor 2: Mounted on the fixed machine frame—enabled during reverse (unwind) direction
Instead of repositioning a single sensor when direction changes, operators simply switch which sensor is active via the controller touchscreen or a PLC command over EtherNet/IP, PROFINET, or EtherCAT.
This eliminates sensor repositioning time, enables instant direction changes, and simplifies machine design by removing the need for motorized sensor positioners.
