High Accuracy Sensing with Slim-size Sensor
Slim Small
amplifier extremely slim, just 10mm thick. This results compact size even several amplifiers mounted row. Moreover, sensor head also extremely small, smallest being just "2.8mm (GH-2S).
Reliable
sensor heads (GH-3S, GH-5S, GH-8S GH-F8S) have IP67 protection. Further, tightening torque been significantly improved thick case.
Accurate
Fine adjustments possible 18-turn, wide adjustment range sensitivity adjuster. Besides, repeatability less temperature characteristics have been improved twice good those conventional models. Hence, suitable high accuracy positioning applications.
