Absolute Encoders for Feedback for CNC/PLC

SHG-A2 Absolute Linear Encoder

Developed to meet a wide range of feedback applications, Newall's Absolute linear encoders provide a true absolute position immediately upon power-up. The encoder does not use batteries or static memory to retain the positional data. True position can be reacquired once power is applied, regardless of duration or power-off movements.


The encoder is ideally suited for linear motor and other high velocity measurement applications including CNC/PLC feedback, pick and place machines, automotive transfer lines, packaging machines, PC-based systems and more.

Description

How Do They Work?
Uniquely coded inserts are placed between the precision balls in the scale. The inserts contain a small magnet that can be detected by a series of hall sensors contained in the reader head. The density of the inserts and the detectors within the reader head allows the encoder to determine fully absolute position. 

Once the encoder has determined the true absolute position it is then a matter for the Digital Signal Processor (DSP) to handle communication of the positional data to the controller.  Being a DSP based absolute system capable of a high level of processing; the encoders are error mapped during manufacturing against a laser interferometer. This error map is stored in FLASH memory allowing it to be applied in real-time thus resulting in a highly accurate encoder.
