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.
