Compact encoders

Posital‘s Optocode encoders with interfaces for EtherNet/IP and Profinet IRT networks are designed for sophisticated motion control applications. Both encoder types can be used in high-speed machines. The EtherNet/IP models, which incorporate an Ertec200 controller, have cycle times of less than 10 ms, while the Profinet IRT models support cycle times as low as one ms (isochronos real-time) and 10 ms (real-time).

The EtherNet/IP models feature a built-in Ethernet switch, while the Profinet version is connected without the need for terminating resistors or switches for address allocation or Baud rate setting. Both models use industry-standard M12 connectors for data communications and power supply. Like all Optocode encoders, they use a proven opto-electronic sensor to determine absolute position values. Angular resolution is 65,536 steps per revolution (16 bits), while up to 16,384 revolutions (14 bits) can be registered in multi-turn mode.
