Encoder Products Company (EPC), a designer and manufacturer of motion sensing devices, introduces its Model A58HE and Model A58SE as Ethernet-ready, multi-turn absolute encoders designed for harsh factory and plant environments. In addition to EtherCAT Deterministic Communication, the models A58HE and A58SE are now made to offer Profinet communication protocol as well.


These encoders are meant to be suited to applications where fieldbus connectivity is required, and the encoder has to retain absolute position information after power-off events. The Model A58HE is a 58 mm encoder in a blind hollow bore construction, and the Model A58SE is a 58 mm shaft encoder available with either a clamping flange or synchro flange, in both compact and heavy-duty configurations. The compact version is the most compact EtherCAT or Prrofinet-capable encoder available through EPC.


Profinet Communication Protocol


The company explains that both the A58HE and A58SE encoders are made to be easily designed into a wide variety of applications. With the heavy-duty model and the compact model, these encoders are versatile mechanically and are accurate.


The Model A58HE and Model A58SE Absolute Encoders are designed withr:


  • EtherCAT Deterministic Communication or Profinet Communication

  • Multi-turn resolution up to 43 bits

  • Single turn resolution up to 16 bits

  • 58 mm diameter housing

  • Bores sizes up to 0.375" or 15 mm

  • Shaft diameters up to 0.375” or 12 mm

  • Durable magnetic technology

  • Proven turns counting technology with no gears or batteries

  • An operating temperature range of -40° C to 85° C

  • A sealing rating of IP65

  • Continuous digital position monitoring

  • The ability to retain absolute position after a power outage

  • CE/EMC Standards for Immunity and Emissions


The Profinet option on the Model A58SE and Model A58HE will be available October 1, 2019.
