EFFICIENT CONTOUR DETECTION USING ONLY A SINGLE LIDAR SENSOR
DETECT EVERY SMALL PART T

he new fork sensors of the GS 04B and GS 08B series from Leuze detect even the smallest objects with absolute reliability. They are ideal for reliable detection in high speed applications.
Even the smallest objects can be reliably detected - as proven by the new Leuze GS 04B and GS 08B series fork sensors. They detect objects as small as 0.05 mm in diameter. Due to their high switching frequency of up to 10,000 HZ, they are well suited for use in fast automation processes. Users benefit from a wide choice of different variants: the sensors of the GS 04B series are available in 14 different fork widths from 5 to 220 mm. The GS(L) 08B series offers four fork widths from 30 to 120 mm. This makes them suitable for a variety of industries - for example in the packaging sector or in assembly and handling technology.
QUICKLY MOUNTED AND CONFIGURED
The compact fork shape of the sensors combines the transmitter and receiver in one device. This enables simple and quick mounting without the need for alignment and offers a high level of operational reliability. Due to their very compact design, Leuze fork photoelectric sensors can also be integrated into areas where space is limited. The extrawide fork widths of 170 or 220 mm, also allow larger objects to be detected. The sensors of the GS 04B and GS 08B series can be configured either via IO-Link or manually via a potentiometer. Sensitivity adjustment and light/dark switching ensure maximum reliability. When it comes to high demands on hygiene and resistance to cleaning agents: the GS(L) 08B series offers a robust, resistant, and cleanroom-compatible V4A stainless steel housing. It is ECOLAB- certified and meets the high standards of protection class IP67.

he unique performance characteristics of Pepperl+Fuchs’ R2000 LiDAR sensor and an intelligent algorithm ensure reliable shadow correction. Minimal
installation effort and quick, straightforward, three-step commissioning round off this highly economical solution. To distribute packages on a conveyor belt as efficiently and evenly as possible for transport to the downstream station, the conveyor belt's current utilization must be detected reliably. The Contour2D sensor system is the most efficient solution for this on the market, comprising a single LiDAR sensor mounted centrally above the conveyor belt. The central position of the sensor means that it detects shadows of packages on the conveyor belt, which would ordinarily distort the measurement results of the system. However, the high angular resolution of the R2000 2-D LiDAR sensor combined with an intelligent algorithm makes corrections for these shadows. The sensor system's Multi Scan Evaluation Unit (MSEU) takes care of running the algorithm and the further processing of the raw data from the LiDAR sensor. Since there are only two components (sensor and MSEU) to install, the Contour2D impresses with very low hardware costs and minimal installation effort. Unlike conventional systems, there is no need for time-consuming configuration to align several sensors with each other. And since only a single sensor is mounted centrally above the conveyor belt, installation requires no major adjustments to the conveyor belt. Therefore, even existing plants can be retrofitted easily.
