Key Technical Specifications

Core Product Advantages

Ultra-high measurement accuracy to meet precision inspection requirements

The GT2-H32 uses KEYENCE's original optical detection principle combined with a high-precision mechanical probe structure, which can achieve 0.5 μm repeatability accuracy in the full measurement range of ±20mm. Whether it is the thickness detection of thin-film materials, the step height measurement of printed circuit boards, or the runout detection of rotating shaft workpieces, it can output stable and reliable measurement data, helping enterprises to achieve 100% full inspection of product quality and reduce the outflow of defective products.

Strong anti-interference ability, stable operation in harsh industrial environments

The sensor head of GT2-H32 adopts a fully sealed structure with IP64 protection class, which can effectively resist the intrusion of dust, oil mist and water splashes in the production workshop. At the same time, the built-in unique noise suppression algorithm can avoid the interference of ambient temperature change, vibration and electromagnetic on the measurement results, and ensure that the measurement error is controlled within the allowable range during long-term continuous operation.

Flexible installation, compatible with a variety of automation scenarios

Adopting a separate design of the sensor head and the amplifier unit, the GT2-H32 can achieve flexible installation in narrow equipment space. The probe can be fixed by standard mounting threads, and can be adapted to different installation directions and angles, which is convenient for integrating into existing production lines or testing equipment. At the same time, the sensor supports a variety of output methods, which can seamlessly connect with PLC, industrial computer and other control systems, reducing the difficulty of equipment transformation.

GT2 Series Model Comparison

KEYENCE GT2 series provides a variety of sensor head models to meet different measurement range and accuracy requirements. The following is a comparison of common models of the same series for your selection reference:

From the comparison results, the GT2-H32 has a very high cost performance in the medium measurement range. It balances the requirements of accuracy, range and use cost, and is the most widely used general model in the GT2 series.

Recommended Matching Combinations

The GT2-H32 sensor head needs to be used with the GT2 series amplifier unit. We recommend the following matching solutions according to different application requirements:

Basic industrial inspection solution

Matching:GT2-H32 + GT2-75N(digital amplifier with NPN output)
This solution is suitable for most conventional size inspection and positioning scenarios, supports RS-232C communication output, can directly connect with the mainstream industrial control system on the market, and is suitable for automated production lines, special testing equipment and other scenarios. The cost is moderate, and it can meet the conventional measurement accuracy and response speed requirements.

High-speed continuous inspection solution

Matching:GT2-H32 + GT2-76N(high-speed digital amplifier with NPN output)
The amplifier supports 10kHz full-speed response, which is suitable for high-speed production lines that require continuous inspection, such as online thickness inspection of rolled materials, appearance inspection of high-speed moving workpieces, etc. It can output measurement data in real time, ensuring no missing detection in the production process.

Multi-sensor synchronous detection solution

Matching:Multiple GT2-H32 + GT2-1000 (main amplifier) + GT2-CHM expansion module
For scenarios that require multi-point synchronous measurement (such as flatness detection of large workpieces, coaxiality detection of shaft parts), you can choose 2-8 GT2-H32 sensor heads to match the main amplifier and expansion module. This solution can realize synchronous data acquisition of multiple channels, simplify system wiring and reduce the difficulty of system integration.

Analog output integration solution

Matching:GT2-H32 + GT2-500(analog output amplifier)
If you need to access the traditional analog control system, this matching method can output 4-20mA or 0-10V analog signals corresponding to the displacement, which is convenient for connecting with the old equipment control system and is suitable for the transformation of the old production line.
