High-Speed Laser Sensors from Keyence
Laser measuring sensor.
Woodcliff Lake, NJ — New from Keyence, versatile high-speed LJ-G Series 2D laser sensors accurately measure the surface profile of targets in the X and Z directions. Called the fastest in its class with a high-speed sampling of 3.8ms and high-accuracy of ±0.1 percent full scale in the Z-Axis, the LJ-G can perform 8-point measurements, making 100 percent inspections possible.

Five sensor-head types ranging from 15mm to 200mm can handle tight specifications for many applications in a wide range of industries. The all-in-one controller allows easy setup on screen or using the LJ-G Navigator software (optional).

Also available is the capability to connect two sensor heads to one controller. According to the company, the sensors are designed for intuitive operation, with user-friendly setup, to make programming and troubleshooting simple.

The new sensor achieves a high-speed of 3.8ms with the Quatro link system that enables accurate measurements on fast production lines or moving targets. Equipped with the E3-CMOS image sensor that provides stability, the LJ-G can measure virtually any targets ranging from black rubber (weak reflection) to metals (strong reflection). In addition, a 2D Ernostar lens is used to provide the optical system with optimal accuracy.

Measurements of width, profile and distance can be made using 28 modes at 8 different points simultaneously: peak height, bottom height, average height, gap, width/position, section area, angle/intersection, profile comparison. A wide area coverage enables fast measurement without moving the sensor or the target. IP67 rating ensures that the LJ-G will operate safely in a water spray environment.

A multifunctional controller satisfies any need. It provides dual independent analog and discrete outputs, RS-232 port, Ethernet port, a 2-sensor head capability. A high-capacity internal memory can potentially store up to 160 programs, 1034 profiles or 65,000 data points. Simple setting, data storage and analysis can be performed with the optional LJ-Navigator software.
