Additional Options

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.
