Safety, Sensors, and Encoders

A position encoder on an axis with a heavy load serves to confirm its position, and while providing higher process accuracy it also adds redundancy that increases the safety of people and processes adjacent to that load. Area guarding by scanners and light curtains adds protective fields to machines that allow them to both stop when necessary and re-start immediately without requiring extra operator intervention, potentially reducing down-time. Safety interlocks for access control can provide similar outcomes mechanically. G&G offers many types of sensors for safe, productive operation.
