High-Accuracy Digital Contact Sensor GT2 series
A Digital Contact Sensor (LVDT) That Can Be Used Anywhere
Contact measuring instruments can be used in areas were non-contact sensors cannot. Thanks to KEYENCE’s measuring range and stroke length options, our sensors can be installed even when space is limited.
- High precision
- No loss of accuracy throughout the measurement range
- IP67G tough head allows for long-term use even in oily environments
- Supports digital I/O, analog, digitial read out, and multiple communication protocols
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.

Features
IP67G Oil-Resistant Design for Measurement in Machine Processing and Other Oily Environments
The sensor head - including the connector and cable section - are IP67G and NEMA Type 13 compliant. This means that stable measurement is achieved even in harsh environments containing splashing water or oil. In order to improve robustness - a common problem with contact sensors - careful attention was paid to the structure of the sensor body. The design incorporates a high-strength linear ball bearing and a seamless body for additional durability. In addition, the reduced weight of the spindle means minimal wear from friction and significantly improved durability. These design improvements reduce maintenance and equipment downtime.
