## Question

What is the difference between the ODC Family and 1DC Series for edge guiding?

## Short Answer

ODC uses external controller with touchscreen. 1DC has built-in controller for PLC integration. Same accuracy.

## Detailed Answer

Both use the same fiber-optic sensing technology and achieve identical accuracy. The **ODC Family** requires an external controller (SCU5 or SCU6x) with a touchscreen interface—ideal for end users who want easy setup without programming. The **1DC Series** has the controller built-in and connects via EtherNet/IP, PROFINET, EtherCAT, or Modbus/TCP—ideal for OEMs and users who prefer PLC integration. Pricing is similar between the two options.
