Overview

The RM44 is an encoder for mounting on electric motors or other devices for measuring shaft position and speed. The solid metal housing offers highest IP protection classes, high EMC immunity, an extended operating temperature range and best possible shock and vibration resistance. Output signals are provided in industry standard absolute, incremental, analogue sinusoidal and linear voltage formats.

Resolutions of up to 13 bits absolute SSI and/or 8,192 counts per revolution incremental for 5 V or 24 V power supply are available.

The RM44 with external zeroing is designed for setting the encoder zero position by using a zero pen. It is designed for a supply voltage of 5 V only.

Features

  • High speed operation to 30,000 rpm
  • Absolute - to 13 bit (8192 counts per revolution)
  • Industry standard absolute (SSI, BiSS C), incremental and analogue output formats
  • Accuracy to ±0.5°
  • Power supply 5 V or 24 V

Benefits

  • Low cost for OEM integration
  • Excellent immunity to IP68
  • Non-contact, frictionless design
  • Simple installation
  • RoHS compliant
