It uses a quartz glass scale and CMOS image sensor projection system to deliver absolute-type position measurement without tracking errors. The air-cylinder configuration allows consistent contact pressure and smooth measurement of moving parts or delicate components. Its IP67-rated housing, corrosion-resistant stainless steel contact, and high vibration resistance make it ideal for precision measurement in machining, assembly, and inspection environments. Key Features: High Precision Measurement: Achieves 0.5 µm resolution and 2 µm accuracy (p-p). 12 mm Measuring Range: Suitable for a wide range of measurement applications. Quartz Glass Scale: Provides excellent thermal stability and long-term accuracy. Air Cylinder Model: Ensures constant measuring force with smooth linear motion. High-Speed Sampling: 1 ms response time for real-time detection in automation. Durable Construction: Zinc die-cast body with aluminum and stainless steel components. Environmental Protection: IP67-rated enclosure for protection against water and dust. LED Status Indicators: Dual-color LED (red/green) for easy status confirmation. Strong Mechanical Endurance: 1 MPa pressure resistance and vibration-tested durability. Compact and Lightweight: Designed for easy installation and integration in measurement systems. The GT2-A12 delivers outstanding precision and reliability for both contact-type measurements and automated in-line inspection systems.
