Absolute Encoder
A new and unique approach to motion control
The Rotalink absolute encoder is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. The sensor determines the orientation of a magnet attached to the output shaft and calculates a binary code (10-16 Bit as required). The absolute encoder is tolerant of stray magnetic fields due to a local measurement technique and Hall sensor conditioning circuitry.
The encoder can be programmed at Rotalink to provide either:
- Options with and without RS422 interface
- SSL interface (3-wire or 2-wire)
- PWM output (with non RS422 version)
- Quadrature output for incremental encoding is opional upon request (with non RS422 version)
Option 1: Non RS422
The non RS422 version provides an SSL interface with the possibility to include PWM output of the absolute position and AB quadrature output.
Option 2: RS422
The RS422 version has the benefit of a robust communication layer for the SSI interface. RS422 is a serial communication standard that is used for transmitting digital data over long distances between devices.
Overall, RS422 is a robust and reliable standard that offers many advantages for long-distance communication and high-speed data transmission.
