Product Description

The Keyence GT2-H12 is a high-precision digital contact sensor head designed for accurate displacement and position measurements in industrial automation applications. Utilizing a quartz glass scale and CMOS image sensor projection system, it offers a measuring range of 12 mm with a resolution of 0.5 µm and an indicated accuracy of 2 µm (p-p). The sensor features a compact design with a mechanical response frequency of 10 Hz and a sampling cycle of 1 ms, ensuring precise and rapid measurements. It is classified with an IP67 enclosure rating, providing resistance to dust and water, making it suitable for harsh industrial environments. With an operating temperature range of -10 to +55°C and a relative humidity tolerance of 35 to 85% (non-condensing), it ensures reliable performance across various conditions.
