This model utilizes a 655 nm red semiconductor laser with Class II safety rating and 0.95 mW output, ensuring accurate detection of small targets and subtle surface variations. Its die-cast aluminum body provides mechanical rigidity and thermal stability, while IP67 protection allows reliable use in harsh factory conditions. The LK-G32 integrates seamlessly with Keyence LK-G controllers for advanced signal processing, temperature compensation, and real-time feedback. Key Features: Compact High-Precision Design: Small-spot laser for accurate detection of micro features and fine edges. High Measurement Accuracy: Ensures ±0.05% of full-scale linearity for consistent dimensional accuracy. Exceptional Repeatability: Achieves 0.05 µm repeatability for ultra-stable measurements. Fast Sampling Frequency: Selectable from 20 Hz to 1,000 Hz to match process requirements. Rugged Aluminum Housing: Die-cast body enhances durability and vibration resistance. IP67 Protection Rating: Fully sealed for dust and water resistance in industrial environments. Temperature Compensation: Maintains accuracy with 0.01% F.S./°C temperature characteristics. Visible Red Laser: 655 nm wavelength provides clear positioning and targeting. Wide Environmental Range: Operates reliably from 0 to +50 °C and up to 85% relative humidity. High Ambient Light Tolerance: Resists up to 10,000 lux from incandescent or fluorescent lighting. The LK-G32 delivers the reliability and precision required for demanding dimensional measurement, surface profiling, and process control applications.
