Available. The Keyence GT2-S5 is a high-precision digital contact sensor head designed for precise measurement applications. Part of the GT2 series, it offers a measuring range of 5 mm and an operating range of 7 mm, with a resolution of 0.1 µm and an indicated accuracy of 1 µm (P-P). The sensor head utilizes a differential transformer detection system and operates with a sampling cycle of 1 ms and a mechanical response of 20 Hz. It features a two-color LED (red, green) operation indicator light and is built to withstand environmental conditions with an enclosure rating of IP67G (JIS) and IP67 (IEC). The ambient temperature range for operation is -10 to +55 °C (14 to 131 °F), and it can handle relative humidity levels from 10% to 85% RH (non-condensing). The sensor head is constructed with a SUS430F main body case, a PUR sensor head-relay connector cable, and a PPSU relay amplifier. The dust boot is made of NBR, and the contact is composed of SUS304 and cemented tungsten carbide. The weight of the sensor head is approximately 40 g (not including cable).
