Information About LK-G157
The LK-G157 belongs to Keyence’s high-performance LK-G laser displacement sensor series, optimized for long-distance measurement applications that require high accuracy and stability. Its wide-beam design ensures consistent detection on surfaces that may scatter light unpredictably, making it suitable for metalworking, electronics, assembly automation, and dimensional inspection. The sensor provides a generous ±40 mm measuring range and maintains exceptional linearity and repeatability, even at extended distances. Its selectable high-speed sampling frequencies support dynamic measurement tasks, while the IP67-rated aluminum die-cast housing enables reliable operation in harsh factory environments.
Key Features:
- Wide-Beam Long-Distance Detection: Provides a stable laser profile capable of measuring diverse surface types, including reflective, rough, or uneven materials at 150 mm reference distance.
- High Measurement Precision: Offers ±0.05% full-scale linearity and 0.5 µm repeatability, delivering extremely accurate results for inspection and positioning applications.
- Fast Sampling Response: Supports high-speed sampling down to 20 µs, enabling real-time measurement for fast-moving production processes or vibration monitoring.
- Robust Industrial Protection: IP67 aluminum die-cast housing resists dust, water, vibration, and mechanical shock for continuous operation in demanding environments.
- Dynamic LED Feedback: Built-in LEDs clearly indicate whether targets are centered, within range, or outside the measurement zone, simplifying setup and diagnostics.
- Wide Environmental Compatibility: Operates reliably across temperatures from 0 to 50 °C and in ambient lighting up to 5000 lux, suitable for most indoor industrial settings.
- Versatile Measuring Range: ±40 mm detection capability supports a broad range of industrial measurement tasks, from component alignment to profile scanning.
- Seamless Integration with LK-G Controllers: Part of Keyence’s modular LK-G ecosystem, enabling advanced signal processing and multi-sensor configurations.
The LK-G157 delivers the reliability and precision required for long-range, high-accuracy laser measurement in modern industrial automation and inspection systems.
