GT2-H12KLF Keyence GT2 Series Digital Contact Sensor Head
The GT2-H12KLF is a box-type digital contact sensor head from the Keyence GT2 series. It uses the Scale Shot System. This absolute detection method removes tracking error. The head offers a 12 mm measuring range and 0.1 µm resolution. It suits high-accuracy dimensional inspection in automated lines.
This sensor head delivers 1 µm (p-p) indicated accuracy. Measuring force varies by mounting direction. Downward mounting needs 0.4 N. Side mounting needs 0.3 N. Upward mounting needs 0.2 N. A 1 ms sampling cycle supports fast inline measurement. Mechanical response reaches 4 Hz at 20 °C. A two-colour LED shows red and green status.
The GT2-H12KLF has no built-in ports or protocols. It connects to a GT2 series amplifier through an M8 connector. The amplifier supplies power. This modular design simplifies replacement and system integration.
