The GT2-H12F belongs to the Keyence GT2 series of high-accuracy digital contact sensor heads. Engineers use this box-type, low-stress sensor for precise dimensional measurement on production lines. Moreover, its Scale Shot System delivers absolute position data without tracking error. As a result, the sensor keeps stable readings even after power interruptions. The 12 mm stroke suits small-part inspection, thickness checks and position verification. Meanwhile, the 0.5 µm resolution captures tiny dimensional changes. Therefore, this sensor head supports quality control tasks that demand repeatable micron-level results.
The GT2-H12F uses the Scale Shot System, an absolute type detection method. This design removes tracking error and keeps position data reliable. Specifically, the measuring range reaches 12 mm with a resolution of 0.5 µm. Indicated accuracy stays within 2 µm (p-p), which suits strict inspection work. Besides, the sampling cycle runs at 1 ms for fast data capture.
Measuring force depends on mounting direction. Downward mounting produces 0.4 N, side mounting produces 0.3 N, and upward mounting produces 0.2 N. This low-stress design protects soft or delicate workpieces. Additionally, a two-colour LED (red and green) shows operation status clearly. The mechanical response reaches 4 Hz at 20 °C.
The sensor head carries no built-in ports and no communication protocols. Instead, it connects to a GT2 series amplifier via an M8 connector. Therefore, power supply, output type and power consumption come from the amplifier, not the head itself. This modular layout simplifies replacement and reduces wiring cost. For system builders, the amplifier handles display, judgment and external output. Meanwhile, the head focuses on accurate, low-stress measurement.
The GT2-H12F operates from -10 to +55 °C without freezing. Relative humidity must stay between 35 and 85 % RH with no condensation. Furthermore, the protection rating reaches IP67 under IEC standards. This rating allows use in dusty or wet workshop environments. The unit weighs approximately 100 g without cable. Its compact box shape fits tight fixtures and small machines.
First, mount the sensor head firmly on a stable bracket. Keep the measuring axis aligned with the target surface to avoid side load. Next, choose the mounting direction that matches your force needs. Downward mounting gives 0.4 N, while upward mounting gives only 0.2 N for fragile parts. After that, connect the M8 connector to a compatible GT2 amplifier. Then, set the amplifier parameters such as response speed and judgment thresholds.
During operation, watch the two-colour LED for status feedback. Green usually means normal measurement, while red signals an alarm or out-of-range condition. In addition, keep the stem clean and avoid sudden impact. Finally, verify accuracy with a gauge block after installation. This step confirms that the GT2-H12F reads correctly in your fixture.

Q1: What amplifier works with the GT2-H12F?
A: The GT2-H12F works with Keyence GT2 series amplifiers. It connects through the M8 connector. Therefore, you must pair it with a compatible amplifier for power and output.
Q2: Does the sensor need calibration after mounting?
A: Yes. After mounting, verify readings with a gauge block. This check confirms accuracy in your fixture. Besides, the absolute system keeps position data without re-zeroing after power loss.
Q3: Can I use this sensor for soft materials?
A: Yes. The low-stress design and 0.2 N upward force suit soft or thin parts. Moreover, the 0.5 µm resolution still captures small changes.
Q4: What is the protection rating of the GT2-H12F?
A: The unit carries an IP67 rating under IEC standards. Therefore, it resists dust and brief water exposure. However, avoid continuous submersion.
Q5: How fast is the sampling cycle?
A: The sampling cycle is 1 ms. Meanwhile, mechanical response reaches 4 Hz at 20 °C. This balance suits both fast capture and stable contact measurement.
