KEYENCE LK-G5000 Laser Displacement Sensor uses a newly developed RS-CMOS sensor to provide a sampling rate of 392 kHz – eight times faster than previous models. With ±0.02% Full Scale Linearity and 0.01µm repeatability, the sensor also has several additional capabilities. ABLE (Active Balanced Laser Control Engine) II balances laser emission time, laser power and gain for optimum performance. The sensor has three selectable built-in algorithms:
1-Real Peak Detect (RPD) algorithm avoids pattern distortion of translucent object
2-Multi-Able Control optimizes the laser intensity for transparent targets
3-Center and Peak Composition (CPC) algorithm attains more stable high-definition measurements for high luster resins
The LK-G5000 can also measure speed and acceleration while measuring displacement.

Laser Sensor Can Measure Displacement 2 Meters From Sensor
Measurement technology company Micro-Epsilon has launched a new laser sensor with a 1m measuring range. The optoNCDT 1710-1000 sensor has a measuring range that starts from a distance of one metre from the sensor, so displacement can be measured at a distance of 2m from the sensor. The sensor comes with an integrated controller in a compact 200mm x 83mm x 48mm housing. The diameter of the light spot is constant across the complete beam path. With a measuring rate of 2.5kHz, the sensor is technically superior to existing alternative sensors on the market, providing 100µm resolution without averaging. 4-20 mA, 0-10V, RS422 or USB outputs are available.
The optoNCDT 1710-1000 is used for measurement objects that have a high degree of freedom or movement. Other potential applications are in harsh ambient conditions, where the sensor has to measure onto the object from a safe distance or if the target is in a vacuum. The sensor also performs very well in high target temperatures or when it is not possible to mount the sensor close to the target. Like all other models in the 1700 series, the optoNCDT 1710-1000 also benefits from a unique RTSC circuit for the real-time compensation of surface influences. This means that a high quality signal is obtained even when changing reflections occur from the target surface.
