Laser Displacement Sensors
KEYENCE's laser displacement sensors enable non-contact measurement of a target's height, position, or distance. By pairing multiple sensors, measurements such as thickness and width can also be performed. High-accuracy displacement sensors can be grouped into two categories: confocal and laser triangulation. Both provide accurate, reliable solutions for non-contact measurement, but depending on the application one type may offer an advantage over the other.
Products Lineup : High Precision Measurement (Reflective Distance Sensors)
The CL-3000 Series confocal displacement sensors are compact 1D laser displacement sensors that use a unique method to ensure high-precision measurement on any material or surface. Using a confocal sensor enables stable measurement on materials ranging from dark rubber to clear films without having to adjust mounting or measurement settings. The sensors are designed with only the lens inside the heads, making them both compact and lightweight, which is ideal for installation in narrow spaces or on robots. All electronics are kept away from the measurement location in the optical unit, providing a stable result that is unaffected by heat or electrical noise. Equipped with features like quad spot processing and optical axis alignment, this series is well suited for a variety of industries and applications, including position or thickness measurement, and it can accurately measure on curved, uneven, or even rough surfaces.
The laser triangulation displacement sensors of the LK-G5000 Series offer high speed and high accuracy for non-contact displacement measurement applications. The sensors utilise advanced hardware such as the RS-CMOS and HDE lens pack to provide reliable results on a range of materials by ensuring the returned light is always in focus. This technology creates a sensor with superior linearity (0.02% of F.S.) and repeatability (0.005 µm). With a max sampling speed of 392 kHz, the LK-G5000 Series can reliably monitor vibrations or catch small changes in fast-moving targets. The head lineup is designed to support a variety of industries and applications, allowing users to select the ideal sensor based on their requirements for measurement range, accuracy, and beam spot size.
The LK-G3000 Series laser displacement sensors employ high-accuracy Li-CCD and ernostar lensing to provide a flexible solution for measuring displacement. This series offers a broad range of sensor heads to support applications requiring high accuracy or large standoff and has a maximum range of 1 metre. The sensors are equipped with a function (ABLE) that automatically adjusts the settings to optimise the reflection from different surfaces, making it possible to measure translucent, rubber, or metal materials stably.
Products Lineup : Reflective Distance Sensors
IX Series image-based laser sensors can measure height anywhere within the area. Camera-based image recognition allows the laser to detect the height of the target point even when workpieces are not perfectly aligned on the production line. The height of where the laser hits the target will vary if the target is tilted or if the target itself is different, but the IX Series can identify the difference in height against the reference. For example, in a parts assembly line, a single IX Series unit can not only check for the presence of parts, but also perform seating checks and other height-based inspections. Thanks to its ability to detect height differences, the IX Series is also free from false detections and errors in the presence of glare from glossy surfaces of metal parts or when the detection target point has the same colour as the background, offering stable automatic inline differentiation.
