Additional Info

The SHG-A Series of absolute linear encoders provide a true absolute position immediately upon power-up. The encoders do 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.

Note: Prices include scale, reader head, scale support brackets. *Contact us for travels not shown.

The Newall Advantage

IP67 rating (NEMA 6)
Withstands dust, dirt, oil and other harsh environmental conditions
No mechanical wear characteristics
Requires no cleaning or maintenance
High tolerance to shock and vibration
High reliability

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.
