NX-ECC222

Overview of Omron NX-ECC222

The Omron NX-ECC222 is an incremental encoder input unit designed for the NX I/O system with EtherCAT communication. It supports two channels of PNP incremental encoder input with a maximum encoder input frequency of 500 kHz for phases A and B and 125 kHz for phase Z. The unit features push-in connectors for easy wiring and a compact 12 mm wide form factor. It operates with a 24 V DC power supply and provides free-running, synchronous, and task-period prioritized refreshing modes, enabling precise and flexible position feedback integration in automation systems.
