The GT2-H12K extends the Keyence GT2 series with a box-type high-precision design. Specifically, it targets applications that need a rigid housing and a 12 mm stroke. Unlike pencil-type heads, this model offers greater mounting stability. Moreover, its construction tolerates tougher factory conditions. Therefore, it fits both manual gauging stations and automated inline inspection.
The GT2-H12K provides a measuring range of 12 mm. Its resolution reaches 0.1 µm for fine position detection. Additionally, the indicated accuracy is 1 µm (p-p). The sampling cycle is 1 ms, so the head tracks fast motion reliably. Meanwhile, the mechanical response is 10 Hz at 20 °C. These figures support repeatable measurement in high-volume production.
Measuring force varies with mounting direction. For instance, downward mounting produces 1.0 N. Side mounting yields 0.9 N, while upward mounting gives 0.8 N. Furthermore, these values help users match the head to workpiece stiffness. Therefore, the GT2-H12K adapts to vertical and horizontal fixtures without extra hardware.
This sensor head uses the Scale Shot System with absolute detection. As a result, it shows no tracking error during power cycles. Besides, position data remains valid after an interruption. The head itself carries no built-in ports or protocols. Instead, it links to a GT2 series amplifier through an M8 connector. Consequently, the amplifier supplies power and manages the output signal.
The GT2-H12K operates from -10 to +55 °C without freezing. Its humidity range is 35 to 85 % RH with no condensation. Moreover, the enclosure meets IP67 under IEC standards. This rating blocks dust and withstands temporary water exposure. The head weighs approximately 95 g without cable. In addition, a two-colour LED shows red and green status at a glance.
First, secure the GT2-H12K onto a flat rigid surface using its box-type mounting holes. Next, align the spindle perpendicular to the measured surface. After that, connect the M8 connector to a compatible GT2 series amplifier. Then, choose the mounting orientation that matches your required measuring force. Finally, power the amplifier and confirm the LED indicator. Rigid mounting reduces vibration error and improves repeatability.
