Information About GT2-A12
The GT2-A12 belongs to Keyence’s GT2 Series of digital contact sensors, known for their high accuracy and robust construction. 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.
