Introducing Delta's new sensor product: Area Sensor [Copy link]

    Following the upgraded PS-R series photoelectric sensors, this time we introduce a new member of Delta's sensor family - the area sensor. The principle of the area sensor, also known as the "light curtain" or "light grating", is similar to that of the through-beam photoelectric sensor. Both detect by detecting the object blocking the optical axis between the transmitter and the receiver. The difference is that the photoelectric sensor detects the presence or absence of an object at a certain point, while the area sensor can detect objects within a plane area. If ordinary photoelectric sensors are used to detect the presence or absence of objects within a certain area, the required number of photoelectric sensors need to be installed in parallel. Obviously, compared with installing the optical axes of many photoelectric sensors in the same plane, the installation and adjustment of the area sensor is much more convenient. Light curtains are divided into three categories: ordinary light curtains, safety light curtains, and measurement light curtains. The area sensor launched by Delta this time is a common light curtain, which can be applied to a variety of protection detection scenarios: 1) Detection of falling workpieces with uncertain paths. Photoelectric sensors can only detect the presence of objects at a certain position. When the path position of the falling workpiece is uncertain, it cannot be detected. The light curtain can detect the presence of objects in an area to prevent missed detection. 2) Prevent the selection of wrong parts. There may be many similar parts around workers on the assembly line. In order to prevent workers from installing the wrong parts, light curtains can be installed outside each part basket. By setting a specific sequence, an alarm will be immediately triggered when the worker's hand reaches into the wrong part basket to improve product yield and quality. 3) Detection of workpieces with a wide positioning area. When the line needs to detect the presence of objects of different sizes or with hollows, photoelectric sensors are prone to missed detection. Area sensors can solve this problem well. 4) Anti-intrusion detection, which can be used for anti-intrusion detection of the working area of small special machine tools to prevent operators from mistakenly entering dangerous areas. It can also be used for anti-intrusion detection of conveyor belts to prevent foreign objects from mixing into conveyor belts. 5) Robot motion restriction, which is used to prevent the robot from interfering with the surrounding protection when performing tasks. When the area sensor receives an over-limit logic response, it actively activates the robot's safety stop signal. Applying reasonable motion restrictions that meet operational requirements can not only effectively improve utilization, but also add a safety barrier for operators. Delta area sensors can be widely used in automated production lines such as food and beverage, packaging, electronic components and equipment, warehousing, and machine tool industries. In addition, the sturdy aluminum alloy shell and IP67 protection level can easily cope with various harsh environments such as moisture, oil, and dust.
