Product Description

The Keyence SH-308 is a high-precision inductive displacement sensor head designed for accurate positioning and measurement in industrial applications. With a compact cylindrical shape of Ø8×18 mm, it offers a stable detecting range from 0 to 2 mm and a maximum detecting distance of 5 mm. The sensor achieves repeatability of 0.002 mm and hysteresis of 0.01 mm, ensuring precise measurements. It features a temperature characteristic of 0.08%/°C, providing stable performance across varying temperatures. The SH-308 is housed in an IP67-rated enclosure, making it resistant to dust and water ingress, suitable for harsh industrial environments. Operating within an ambient temperature range of -10 to +60 °C and relative humidity of 35% to 85% (no condensation), it is designed to withstand vibrations with a double amplitude of 1.5 mm at 10 to 55 Hz for 2 hours in each of the X, Y, and Z directions. Weighing approximately 55 g, it is an ideal choice for applications requiring high-accuracy displacement sensing.​
