Information About GT2-PA12
The GT2-PA12 is part of Keyence’s GT2 Series of digital contact sensors utilizing the Scale Shot System II, which eliminates tracking errors and ensures absolute measurement accuracy. It offers a 4 ms sampling cycle for rapid and stable data capture in automated inspection systems. Built from high-strength stainless steel with a fluorine-coated spindle, the sensor is resistant to mechanical wear and contamination. Its air-cylinder actuation enables consistent measuring force, ideal for precision gauging in machining, assembly, and quality assurance applications.
Key Features:
- High Precision: 0.5 µm resolution with ±2 µm indicated accuracy for exact dimensional measurement.
- 12 mm Measuring Range: Supports a wide measurement span for diverse inspection tasks.
- Fast Sampling: 4 ms response time enables high-speed, real-time detection.
- Durable Construction: IP67-rated stainless steel housing resists oil, dust, and water.
- Stable Air-Cylinder Design: Ensures uniform measuring force and reduced mechanical impact.
- Advanced Detection System: Scale Shot System II provides absolute measurement without tracking errors.
- Multi-Directional Mounting: Compatible with downward, side, or upward installation orientations.
- LED Indicator: Two-color (red/green) operation light for easy visual status monitoring.
- Environmental Robustness: Resistant to vibration (10–55 Hz) and shock up to 1,000 m/s².
- Clean Operation: Uses dry air to maintain sensor cleanliness and long-term stability.
The GT2-PA12 delivers the precision and reliability required for high-accuracy displacement and dimensional control in demanding industrial environments.
