Absolute Encoders for Feedback for CNC/PLC: SHG-A4 Linear Encoder

SHG-A4 Linear Encoder

SHG-A4 Incremental Linear EncoderRS485 meets the requirement of a multi-point communication network, which can have up to 32 drivers and 32 receivers on a single two-wire bus. A key feature is the ability to address individual devices. This model can be ordered with unique address tags. Developed to meet a wide range of feedback applications, the SHG-A4 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
