Digital Gauges SA Series – Contact Type Displacement Sensors

These are high-accuracy contact-type displacement sensors that detect the absolute position of the spindle optically and output it with high resolution. In combination with the separately-sold SA Series controllers, these products serve as a length-measuring system. We have also provided new air purge specifications in which air is supplied to the body of the detector to increase its internal pressure, preventing intrusion of foreign matter from outside, which significantly improves its environmental resistance, and enabling use in harsh environments with exposure to highly-penetrating oils, coolants and cutting fluids.

Advanced air-purge technology provides the ultimate, excellent anti-environmental performance.

This air-purge system dramatically increases the resistance to the environment by supplying air to the sensor body to raise the inner pressure and preventing foreign objects from invading from outside. It exhibits strong performance in severe environments where liquids such as permeable oil, coolant liquids and cutting fluids spill over the detector.
