GT2 series - High-Accuracy Digital Contact Sensor

To increase longevity—a common challenge with contact-type displacement sensors—the structure of the main body has been fundamentally re-examined for the High-Accuracy Digital Contact Sensor GT2 Series. The structure, including the relay connector and cable, ensure stable measurement even in environments with splashing water or oil. In addition, the reduced weight of the spindle means minimal friction wear and significantly improved durability. A wide variety of sensor heads are available, including pencil type, air push-type, and low-stress type. The GT2 Series offers two types of detection methods: LVDT (linear variable differential transformer) and Scale Shot System II. This allows use across various applications. The varied lineup of communication units enables communication with PCs and PLCs from various manufacturers.

GT series - General Purpose Digital Contact Sensor

The General Purpose Digital Contact Sensor GT Series is a contact type sensor designed for ease of use and reliability. It can be installed easily in existing facilities, allowing for quick startup of the production line after installation. It also has an easy-to-see display and a self-diagnostic function for checking for conditions such as a trapped spindle or cable disconnection. There are two types of mounting for the amplifier: DIN type for rail mounting and panel type for panel mounting. Selecting the correct type for the installation environment is effective for simplified wiring. Various functions are included to complete the setting with minimum steps. The sensor can be used immediately after installation. The easy-to-see indicators clearly show judgment results and errors during measurement.
