SHG-A2 Linear Encoder
RS232 serial communication is typically used to interface with PC "COM" ports. A serial to USB converter is available to allow interface via a USB port. Developed to meet a wide range of feedback applications, the SHG-A2 absolute linear encoder provides 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.

Quick and Easy Installation
The design of these linear encoders allow installment in almost any position, unlike glass-scale linear encoders, which usually need to be installed with the lip seal facing downwards to prevent contamination. Self-aligning fixing brackets allow virtually effortless scale mounting, needing only a single hole for each set of brackets.
