The GP-X3SE is an ultra-compact eddy current type digital displacement sensor designed for high-speed, high-accuracy measurement of micro-displacements. It features a 25 µs ultra-high sampling speed (40,000 times/sec) that captures even the fastest work displacements, combined with a 0.02 % F.S. resolution enabling differentiation of ultra-micro displacements as small as 0.32 µm. The sensor exhibits excellent temperature stability with 0.07 % F.S./°C temperature characteristics, ensuring reliable measurements across varying ambient conditions. With a compact ø3.8 mm cylindrical form factor, 0 to 0.8 mm sensing range, and IP67G protection rating, the GP-X3SE is ideal for precision industrial applications including eccentricity sensing, stroke end sensing, and height sensing in manufacturing and quality control environments.
