Micro-size Inductive Proximity Sensor Amplifier-separated Product is discontinuedInductive Sensors Diagnosis Self-diagnosis Oil resistant Metal embedding With adjuster possible GXL INDUCTIVE PROXIMITY SENSORS GA-10 SERIES GH SERIES Slim & small Reliable Accurate The amplifier is extremely slim, just 10 mm 0.394 in thick. This results in a co m pac t s iz e e v e n i f s e v e ra l amplifiers are mounted in a row. Moreover, the sensor head is also extremely small, the smallest being just "2.8 mm "0.110 in (GH-2S). The sensor heads (GH-3S, GH-5S, GH-8S and GH-F8S) have IP67 protection. Further, the tightening torque has been significantly improved due to its thick case. Fine adjustments are possible by its 18-turn, wide adjustment range sensitivity adjuster. Besides, its repeatability is 1 !m 0.039 mil or less and its temperature characteristics have been improved to twice as good as those of conventional models. Hence, it is suitable for high accuracy positioning applications.

Moreover, since the cover of the connecting portion is transparent, it is possible to confirm whether the connection is proper. Disconnection alarm indicator Wire-saving If the sensor head cable is damaged, or misconnected, the disconnection alarm indicator (orange LED) lights up for your attention. Amplifier with a plug-in connector, which is connectable to the sensor block of an S-LINK system, or to the sensor block for simple wiring SL-BMW or SL-BW, or to a mating cable, is also available.
