Information About LK-H020
The LK-H020 sensor head is part of the Keyence LK series, known for delivering high accuracy and ultra-stable measurements in industrial inspection and automation. Using a 655 nm red semiconductor laser, the sensor maintains a precise 25 µm beam spot, allowing detection of subtle displacement changes and micro-features. Its diffuse reflective mounting design enables versatile use without requiring a separate receiver, supporting stable measurement across metals, plastics, and irregular surfaces. With selectable high-speed sampling cycles as low as 2.55 µs, the LK-H020 excels in dynamic measurement applications. The rugged aluminum housing paired with an IP67 rating ensures consistent performance under vibration, humidity, and exposure to dust or liquids.
Key Features:
- Ultra-High Measurement Precision: Offers exceptional repeatability down to 0.02 µm and ±0.02% linearity, enabling micron-level accuracy for critical inspection tasks.
- Compact Spot-Type Optical System: Produces a 25 µm laser spot for precise targeting, ideal for detecting small profile variations and component positioning.
- High-Speed Sampling Performance: Selectable sampling rates from 2.55 to 1000 µs provide flexibility for both rapid process monitoring and high-accuracy static measurements.
- Stable Diffuse Reflective Detection: Measures distance without requiring cooperative targets, supporting diverse surface types including reflective, curved, or textured materials.
- Robust Industrial Environmental Resistance: IP67 housing and aluminum die-cast body withstand dust, splashes, vibration, and challenging plant conditions.
- Excellent Temperature Stability: Only 0.01% full-scale drift per °C ensures consistent measurement accuracy across varying ambient temperatures.
- Wide Measurement Range: ±3 mm displacement range at a 20 mm reference distance offers versatility for fine-scale positioning and surface inspection.
- High Ambient Light Immunity: Operates reliably under industrial lighting up to 10,000 lux, reducing installation constraints and false detection risks.
The LK-H020 delivers the reliability and precision required for micro-measurement, machine automation, and advanced quality control in demanding industrial environments.
