The GT2-H32 belongs to the Keyence GT2 series of high-accuracy digital contact sensor heads. Engineers choose this box-type, long-range model for larger dimensional checks on production lines. Moreover, its Scale Shot System delivers absolute position data with no tracking error. As a result, the sensor keeps stable readings even after a power interruption. The 32 mm stroke suits thick-part measurement, step detection and position verification. Meanwhile, the 0.5 µm resolution still detects very small dimensional shifts. Therefore, this sensor head supports quality tasks that demand both wide travel and micron-level repeatability.
The GT2-H32 uses the Scale Shot System, an absolute detection method. This design removes tracking error and keeps position data dependable. Specifically, the measuring range reaches 32 mm with a resolution of 0.5 µm. Indicated accuracy stays within 3 µm (p-p), which suits strict inspection work. Besides, the sampling cycle runs at 1 ms for fast data capture.
Measuring force changes with mounting direction. Downward mounting produces 2.1 N, side mounting produces 1.8 N, and upward mounting produces 1.5 N. This stronger force suits larger strokes and firmer contact needs. Additionally, a two-colour LED (red and green) shows operation status clearly. The mechanical response reaches 6 Hz at 20 °C.
The sensor head carries no built-in ports and no communication protocols. Instead, it connects to a GT2 series amplifier through an M8 connector. Therefore, supply voltage, output type and power consumption come from the amplifier, not the head itself. This modular layout simplifies replacement and lowers wiring cost. For system builders, the amplifier handles display, judgment and external output. Meanwhile, the head focuses on accurate, long-range measurement.
The GT2-H32 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 270 g without cable. Its larger box shape reflects the longer 32 mm stroke and stronger internal mechanism.
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 2.1 N, while upward mounting gives 1.5 N for lighter contact. 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-H32 reads correctly in your fixture.

Q1: What amplifier works with the GT2-H32?
A: The GT2-H32 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: When should I choose the 32 mm model over a 12 mm head?
A: Pick the GT2-H32 when your workpiece needs more than 12 mm of travel. Its longer stroke handles thick parts and larger steps. However, the 12 mm models offer lower measuring force.
Q3: 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.
Q4: What is the protection rating of the GT2-H32?
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 6 Hz at 20 °C. This balance suits both fast capture and stable contact measurement.
