The Beckhoff EL5101 EtherCAT Terminal is a compact 1-channel encoder interface for precise position measurement in machine automation, motion control and industrial control systems. Designed for incremental encoders with 5 V DC signals, it supports both differential RS422 and single-ended TTL connections, making it a flexible choice for demanding B2B applications.

This EtherCAT encoder terminal provides 4-fold quadrature evaluation up to 1 MHz, with a switchable 16/32-bit counter and high-resolution microincrements for accurate speed, frequency and position acquisition. Integrated functions such as wire breakage detection, latch and gate input, edge timestamping, filters and Distributed Clocks support reliable integration into high-performance automation architectures.

With its DIN-rail mounted IP20 terminal housing, electrical isolation and robust industrial approvals, the Beckhoff EL5101 is well suited for control cabinets and OEM machine building, and it is supplied with a 1-year warranty for added purchasing confidence.
