* The zero position is specified when ordering the sensor and can be set at a distance of 30 mm or 50 mm * Non-magnetic spacer No. 1 is required only when the zero position is set at 30 mm from the linear position sensor flange and the sensor sleeve is made of magnetic material.

Interface

EtherCAT (Ethernet for Control Automation Technology) is a high-performance industrial Ethernet protocol standardized under IEC 61158. The protocol supports data transmission rates of 100 Mbit/s and 1 Gbit/s. EtherCAT offers high flexibility in network topology: networks can be built in line, star, ring, tree, or hybrid configurations. No additional Ethernet switches are required for network implementation, which simplifies deployment and reduces costs. Within a single network segment, up to 65,535 devices can be connected, including sensors, servo drives, and programmable logic controllers (PLCs).

Device configuration is performed via ESI (EtherCAT Slave Information) XML files or through a web interface, ensuring convenient integration into existing automation systems.

Synchronization:

Hard Real-Time — hard real-time mode providing a data update cycle of no more than 100 µs.
Distributed Clocks(DC) — enables device synchronization with nanosecond-level accuracy, which is essential for coordinating complex motion systems.

Compatibility with other standards:

CoE – CANopen over EtherCAT –enables integration with CANopen devices.
SoE – SERCOS over EtherCAT – enables integration with SERCOS systems.
EoE – Ethernet over EtherCAT – allows transmission of TCP/IP traffic within an EtherCAT network.

A key feature of EtherCAT is “on-the-fly” data processing: each network node processes the Ethernet frame as it passes through, without buffering. This significantly reduces latency and increases bandwidth efficiency, achieving up to 90% effective payload utilization of the Ethernet frame. The protocol is highly scalable and suitable for systems of any complexity — from local installations to distributed networks with thousands of devices.
