Product Overview

The NX-EC0122 is an Omron NX-series Incremental Encoder Input Unit designed for integration into the Sysmac control platform via EtherCAT. The unit provides a single encoder channel with three external inputs (PNP) and supports pulse, phase-difference, pulse+direction, and up/down pulse input methods. It is used for high-precision motion and position feedback in industrial applications such as servo axis monitoring, indexing machinery, and position control loops. NX-EC0122 offers synchronous and task-prioritized I/O refreshing within distributed clocked control systems.

Best Suited For

  • Single-axis encoder feedback in EtherCAT-based motion systems
  • Position monitoring in servo indexing applications
  • Integration into Sysmac machine controllers requiring PNP logic
  • Applications needing high pulse count range and flexible counter functions
