Product Description

LJ-V7300 Sensor Head

The LJ-V7300 is a sensor head from the LJ-V Series that performs high-speed, high-precision profile measurement using a blue semiconductor laser.

Product Overview

Using diffuse reflection measurement, Keyence LJ-V7300 performs non-contact profile inspection with a reference distance of 300 mm. The sensor head offers a Z-axis measurement range of ±145 mm, providing a total full-scale range of 290 mm. Across the X-axis, the measurable width changes from 110 mm on the near side to 240 mm on the far side, reaching 180 mm at the reference position.

Keyence LJ-V7300 employs a visible blue semiconductor laser with a wavelength of 405 nm and an output power of 4.8 mW. The laser complies with Class 2 requirements according to IEC60825-1 and FDA (CDRH) Part 1040.10. At the reference distance, the spot size is approximately 240 mm × 610 µm, enabling precise profile acquisition. Profile data is generated with an X-axis interval of 300 µm.

High repeatability contributes to reliable measurement performance. Along the height direction, repeatability reaches 5 µm, while the width direction provides 60 µm repeatability. Z-axis linearity ranges from ±0.05 to ±0.15% of full scale, and temperature characteristics are maintained within 0.01% of full scale per degree Celsius. Sampling cycles can reach 16 µs in high-speed mode and 32 µs in advanced function mode, allowing rapid inspection processes.

Environmental durability is another advantage of Keyence LJ-V7300. Both the sensor head and the connection cable support an IP67 enclosure rating when used with sensor head cables or extension cables. Such protection allows operation in locations where water spray is common, including processing plants. The aluminum housing withstands vibrations from 10 to 57 Hz with a double amplitude of 1.5 mm and tolerates shocks up to 15 G for 6 ms. Operation is supported at temperatures from 0 to +45 °C and relative humidity levels up to 85% RH without condensation. For proper use, the sensor head should be mounted on a metal plate.

Technical FAQ

1. What is the measurement principle and optical triangulation architecture of the Keyence LJ-V7300 in high precision 2D and 3D laser profiling applications?

The Keyence LJ-V7300 operates on a high-speed laser triangulation displacement measurement principle, utilizing a laser emitter, reflected light reception, and position-sensitive detection. This configuration enables real-time profile reconstruction and sub-micron level surface height evaluation for dynamic inspection environments.

2. How does the Keyence LJ-V7300 achieve ultra-high sampling rate and high-resolution profile acquisition in industrial metrology systems?

The Keyence LJ-V7300 implements a parallel multi-scan CCD acquisition architecture combined with high-speed DSP processing, enabling extremely fast profile capture. This allows continuous measurement of moving targets without motion-induced distortion, supporting high throughput inline inspection systems.

3. What is the functional role of the multi-layer signal processing engine within the Keyence LJ-V7300 measurement system?

The Keyence LJ-V7300 integrates an advanced signal reconstruction engine that performs noise filtering, peak detection optimization, and waveform stabilization. This ensures robust profile extraction even under reflective, dark, or irregular surface conditions.

4. How does the Keyence LJ-V7300 ensure measurement stability across varying surface reflectivity and material heterogeneity?

The Keyence LJ-V7300 employs adaptive laser intensity control and dynamic exposure compensation, allowing stable detection across highly reflective metals, low-reflectivity plastics, and mixed material surfaces. This ensures consistent Z-axis height accuracy under variable optical conditions.

5. What is the role of 3D reconstruction algorithms in the Keyence LJ-V7300 laser profiler system?

The Keyence LJ-V7300 uses sequential profile stacking and point cloud generation algorithms to reconstruct 3D surface geometry. This enables precise dimensional analysis, flatness evaluation, and geometric defect detection in production lines.
