KEYENCE GT2-P12KF high-precision contact displacement sensor: the precise choice for industrial measurement

In the field of industrial measurement that pursues ultimate precision and reliability, KEYENCE's GT2-P12KF pen contact displacement sensor stands out with outstanding performance. As a member of the GT2 series, it continues the genes of high precision, durability, and environmental adaptability of the series, while further meeting the needs of complex industrial scenarios through innovative design.

Core parameter: Dual breakthrough in accuracy and speed

The core advantage of GT2-P12KF lies in its ability to achieve a resolution of 0.1 μ m and a peak to peak accuracy of 1 μ m within a measurement range of 12mm, which puts it in a leading position among similar products. Its sampling period is only 4ms, and the mechanical response frequency reaches 10Hz, which can quickly capture dynamic displacement changes. The sensor adopts an absolute scale pulse system II, which completely eliminates the tracking error of traditional contact sensors and ensures the absolute reliability of measurement data.

In terms of mechanical performance, the measurement force of GT2-P12KF is optimized according to the installation direction: 1.0N when installed downwards, 0.95N when installed horizontally, and 0.9N when installed upwards (center value of the measurement range). This design balances measurement stability and object protection.

Environmental adaptability: Fearless of harsh working conditions

In response to the complex environment of industrial sites, GT2-P12KF has passed IP67G (JIS) and IP67 (IEC) protection certifications and complies with NEMA Type 13 standards, which means that its sensor heads, relay connectors, and cables all have dustproof, waterproof, and oil resistant characteristics. The specific parameters include:

Temperature range: -10 ℃ to+55 ℃ (without freezing)

Humidity range: 35% to 85% RH (non condensing)

Seismic resistance: at a frequency of 10-55Hz, with a double amplitude of 1.5mm, 2 hours in each X/Y/Z direction

Impact resistance: 1000m/s ² (IEC 60068-2-27 standard)

The sensor head adopts a seamless integrated design, the cable uses PUR oil resistant material, and the relay connector supports detachable flexible cables with a bending radius of only 50mm and a load of only 250g, greatly improving the stability of the equipment in moving or vibration scenarios.

Technical highlight: Innovation driven performance upgrade

1. Grating Scale Pulse System II

By combining ultra clear CMOS sensors with HL-LED light sources, the absolute position information on the glass scale can be directly read, avoiding the cumulative error of traditional pulse counting methods.

2. High hardness linear ball bearings

The spindle is made of stainless steel material, achieving a testing life of 100 million times, reducing friction loss, and significantly reducing maintenance costs.

3. Multi protocol communication capability

Supports multiple interfaces such as USB, PLC, EtherNet/IP, PROFIBUS, etc., and can be connected to computers or PLCs for real-time data management and visual analysis.

4. Application scenario: Covering the entire process of precision manufacturing

The pen design (diameter only 8mm) and flange installation method of GT2-P12KF make it easy to integrate into automation equipment. Typical applications include:

Automotive component testing: such as verifying the sealing of engine diaphragms, avoiding assembly defects through high-precision displacement measurement.

Assembly of electronic components: During the process of attaching small parts, ensure that the positional accuracy reaches the micrometer level.

Mold processing monitoring: Real time detection of mold wear to prevent production failures.

User Value: Dual Optimization of Efficiency and Cost

User feedback shows that the IP67G protection level and oil resistant cable of GT2-P12KF significantly reduce downtime caused by environmental factors, while the 100 million test life reduces long-term maintenance costs. In addition, its supporting software supports automatic sensor recognition and statistical functions (such as maximum value, minimum value, flatness calculation), further simplifying the data management process.

The KEYENCE GT2-P12KF redefines the performance benchmark for contact displacement sensors with its 0.1 μ m resolution, IP67G protection rating, and 100 million durability. Whether it is a laboratory setting that pursues ultimate precision or an automated production line that requires high reliability, GT2-P12KF can provide stable and accurate measurement solutions, making it an ideal choice for quality control in the Industry 4.0 era.
