Overview

The ZeroErr eCoder11 is an axial-reading magnetic absolute encoder with RS485 versions for single-turn or multi-turn absolute value measurement. Select 17-bit or 19-bit resolution configurations. The multi-turn version is available with or without a multiturn counting battery.

Features

  • 11 mm through-hole design for routing mechanical structures, cables, air lines, and similar items through the encoder.
  • Non-contact multi-turn absolute operation is available with the multi-turn RS485 option.
  • RS-485 protocol compatibility with Tamagawa absolute encoders.
  • 8-pin connection; the encoder board has two top-edge connectors and one bottom-edge connector.
  • Programmable zero position stored in internal EEPROM.
  • Point-by-point position compensation is programmable and storable on the 19-bit multi-turn configuration.
  • Specified for use in dust, heavy oil contamination, high- and low-temperature, and complex electromagnetic environments.
  • Designed for convenient installation and controllable accuracy, with a precision positioning reference for fast, accurate installation.

Options

  • Single-turn RS485: 17-bit or 19-bit resolution; multiturn counting battery not included.
  • Multi-turn RS485: 17-bit or 19-bit resolution; multiturn counting battery not included or included (two pieces per pack).
  • 19-bit multi-turn RS485: up to 19-bit resolution, 216 counting revolutions, stated repeatability of ±15″, and programmable, storable point-by-point position compensation.
