Information About LK-H057
The LK-H057 belongs to Keyence’s advanced LK-H series of laser displacement sensors, known for their superior accuracy and stable measurement performance. Featuring a Class 2 red laser and diffuse reflective sensing, the LK-H057 achieves fine measurement results even on challenging surfaces. With a selectable sampling cycle from 2.55 µs to 1000 µs, it delivers both high-speed and high-resolution performance. Its rugged IP67 aluminum die-cast housing ensures reliability in harsh industrial environments, making it ideal for integration into process control, inspection, and precision assembly systems.
Key Features:
- Wide Measurement Range: ±10 mm detection range with a 50 mm reference distance for flexible applications.
- High Precision: Exceptional 0.025 µm repeatability ensures micro-level measurement accuracy.
- Red Semiconductor Laser: 655 nm wavelength for stable, reliable reflection from diverse materials.
- Selectable Sampling Cycle: Adjustable from 2.55 µs to 1000 µs to optimize speed and precision.
- Excellent Linearity: Maintains ±0.02% of full scale (20 mm) for consistent output accuracy.
- Industrial Durability: IP67-rated aluminum die-cast housing withstands moisture, dust, and vibration.
- Temperature Stability: Drift as low as 0.01% of F.S./°C, ensuring consistent results in varying conditions.
- Resistant to Ambient Light: Operates under illumination up to 10,000 lux, minimizing external interference.
- Compact Design: Lightweight (260 g) body simplifies integration into robotic or measurement setups.
- Class 2 Laser Safety: Conforms to IEC 60825-1 and FDA CDRH Class II standards for safe operation.
The LK-H057 delivers the precision, responsiveness, and environmental resilience essential for high-performance displacement and thickness measurement applications in manufacturing and automation.
