The GT2-H50 belongs to the Keyence GT2 series of high-accuracy digital contact sensors. This box-type sensor head uses the Scale Shot System with absolute encoding. As a result, it never loses position data after power loss. Furthermore, the 50 mm measuring range supports long-stroke applications. The 0.5 µm resolution captures very small dimensional changes. Meanwhile, the 3.5 µm indicated accuracy ensures reliable measurement results. This sensor head works with GT2 series amplifiers through an M8 connector. It has no built-in communication ports. Therefore, all signal processing happens inside the amplifier unit. The GT2-H50 suits inline inspection, thickness measurement, and position feedback tasks. Its IP67 rating allows use in dusty or wet factory environments.
The GT2-H50 uses the Scale Shot System, which is an absolute type. This design eliminates tracking errors completely. The measuring range reaches 50 mm. Additionally, the resolution is 0.5 µm. The indicated accuracy is 3.5 µm (p-p). The sampling cycle is 1 ms. The mechanical response is 7 Hz at 20 °C. These values make the sensor head suitable for fast production lines.
The GT2-H50 has no built-in ports or protocols. It connects to a GT2 series amplifier via an M8 connector. The amplifier supplies power to the sensor head. Because of this, supply voltage and power consumption ratings are not available for the head alone. Output type also depends on the connected amplifier. This modular design lets users swap sensor heads without changing the whole system. However, it also means the head cannot work as a standalone device.
The sensor head weighs approximately 320 g, excluding the cable. Its dimensions are not published in the standard specification sheet. The operating temperature range is -10 to +55 °C with no freezing. Relative humidity should stay between 35 and 85 % RH with no condensation. Moreover, the protection rating is IP67 according to IEC standards. This rating means the head resists dust ingress and brief water immersion. As a result, it performs well in machining centers, press lines, and automated assembly stations.
First, mount the GT2-H50 using the correct bracket for your application. The measuring force changes with orientation. For instance, upward mounting gives the lowest force at 2.4 N. Next, connect the M8 connector to a compatible GT2 amplifier. Make sure the connector is tight to maintain the IP67 seal. Then, set the amplifier parameters for resolution and sampling. After that, run a test cycle to confirm the LED status. Finally, secure all cables to prevent strain on the connector. Proper cable routing also reduces measurement noise.

Q1: What is the resolution of the GT2-H50?
A: The resolution is 0.5 µm. This fine resolution supports sub-micron measurement tasks.
Q2: Can the GT2-H50 work without an amplifier?
A: No. The sensor head needs a GT2 series amplifier for power and signal processing.
Q3: What is the measuring range of this sensor head?
A: The measuring range is 50 mm. This long stroke suits deep or wide part features.
Q4: How does mounting direction affect performance?
A: Mounting direction changes the measuring force. Downward mounting gives 3.2 N, side mounting gives 2.8 N, and upward mounting gives 2.4 N.
