With the RMS1000 radar sensor suitable for outdoor use, Sick provides a solution for object detection and collision avoidance. It features a J1939 interface and comes with protection classes IP67 and IP69.
Even in darkness, bright light, heavy rain, snowfall, dense fog, or dusty environments, the sensor “sees” all – and due to the IP67 and IP69 enclosure rating, it also remains permanently sealed, even during high-pressure cleaning, explained the company. At the same time, the aluminum housing protects against mechanical damage. As there are no inner moving parts, impacts, or shocks cannot harm the sensor technology either. This means availability and durability when used as collision protection on cranes, mobile work platforms, aircraft belt loaders and forklift trucks, as well as for person and object detection in open spaces, in halls, on truck ramps, or in locks, the company added.
The sensor uses FMCW (frequency modulated continuous wave) radar technology in the 61-GHz frequency band and was designed for challenging industrial tasks that also require a high degree of sensor adaptability. This applies first of all to the actual detection: With the product, up to four adjustable zones can be monitored and the radial distance and speed of objects – even several at the same time – can be measured at working distances of 0,4 m to 100 m. The sensor can also be integrated into control systems: In this case, it offers the necessary options with, for example, J1939 which is common in automotive networking. Nickel-plated plug connectors and industrial M12 connection technology ensure corrosion-proof, vibration-resistant, and reliable cabling.
The permissible ambient operating temperature is specified as -40 °C to +65 °C. In the event of rapid temperature changes, for example when changing from a freezer area to a heated hall area, a pressure compensation diaphragm compensates for temperature-related pressure changes in the sensor. This maintains complete availability and detection reliability at all times, claimed the company.
The parameterization of the RMS1000 via web browser is intuitive. Here, the horizontal aperture angle can also be set up to a maximum value of ± 60 °, depending on whether a wide or a narrow zone is to be monitored. The measured values can be output as raw data and thus used in a variety of detection and collision protection systems.
The sensor can be used in range of application areas. As a driver assistance system, it is used, among other things, for collision warning on cranes, in mobile automation, or even as a truck docking aid on loading ramps. The device can detect people and vehicles in front of gates and open these automatically. The detection of ships in locks or the non-contact measurement of water levels are other examples of applications.
