LJ-V7200B KEYENCE High-precision laser displacement sensor

KEYENCE LJ-V7200B High-precision laser displacement sensor

Product Description: KEYENCE LJ-V7200B

The KEYENCE LJ-V7200B is a high-precision laser displacement sensor designed for advanced 3D profiling and dimensional measurement. It combines blue laser technology, high-speed data acquisition, and robust industrial design to deliver accurate measurements in challenging environments.

Technical Specifications:

Features:

Blue Laser Technology:

Uses a 405 nm blue semiconductor laser for superior performance on reflective, transparent, or multi-layered surfaces (e.g., glass, film, metal).

Minimizes interference from ambient light and surface texture variations.

High-Speed 3D Profiling:

Captures 2D cross-sectional profiles at up to 8,000 profiles per second (adjustable sampling rate).

Simultaneously measures height, width, angle, and surface irregularities.

Wide Measurement Range:

Z-axis (height) range: 20 mm (standard mode) or 50 mm (wide mode).

X-axis (width) range: 48 mm (standard mode) or 120 mm (wide mode).

Supports multi-sensor synchronization for large-area 3D scanning.

High Resolution & Accuracy:

Z-axis resolution: 0.5 µm (standard mode) or 2 µm (wide mode).

Linearity: ±0.02% of full scale (standard mode).

Industrial Durability:

IP67 protection rating (IEC 60529), ensuring resistance to dust, water, and oil.

Operates in temperatures 0°C to +50°C (non-condensing).

Flexible Integration:

Supports Ethernet/IP, EtherCAT, and Modbus TCP protocols for seamless integration with PLCs and automation systems.

Includes KEYENCE’s dedicated software (e.g., LJ-X Explorer) for real-time data visualization and analysis.

Advanced Applications:

Ideal for battery electrode inspection, semiconductor packaging, automotive component measurement, and 3D surface analysis.

Applications:

Battery Manufacturing:

Electrode coating thickness measurement and edge alignment inspection.

Semiconductors:

Warpage detection in IC packages and lead frame coplanarity checks.

Automotive:

Weld bead profile analysis and brake pad surface roughness measurement.

Electronics:

Solder paste volume inspection and PCB warpage detection.

Medical Devices:

Precision measurement of surgical tools and implantable components.

Notes

Installation Guidelines:

Ensure the sensor head is mounted securely to avoid vibration-induced errors.

Use protective covers in environments with heavy dust or liquid exposure (despite IP67 rating).

Compatibility:

Requires LJ-V7000 series controller for full functionality.

Optional accessories: dust-proof air purge kit, laser safety filters, and mounting brackets.

Maintenance:

Regularly clean the laser window with a lint-free cloth to maintain measurement accuracy.

Avoid direct exposure to strong ambient light sources (e.g., welding arcs).
