Infrared Grating | ALEPH Electronics Technology | Price 7-beam infrared grating is provided by ALEPH Electronics Technology. Guangzhou Yi Li Fu Electronic Technology Co., Ltd. (www.alephchina.com) is located in the East Industrial Park Tong Guang Tong Road One, 3rd Floor, Guangzhou Tianhe District, Guangzhou City, 303, Contact: 陈盛友 ALEPH cross-beam infrared grating Features: 1, very humane independent external terminals, install wiring debugging easier; 2, cross-beam infrared grating anti-theft detectors, the company is in for radio-infrared grating developed on the basis of performance more stable multi-beam active infrared detector; 3, the use of micro aspherical lens careful handling transmitting and receiving ends of the infrared light, that stability is much greater than the distance of the detector to 100 meters (outdoor test distance greater than 600 m); 4, AGC Automatic Gain control circuit automatically adapts to changes in the working environment, to ensure stable and reliable operation of the detector; and 5, exquisite streamlined aluminum enclosure, with the most professional optical filters, to ensure reliable transmission of infrared light, visible light and effectively filter various white light source; 6, using any two adjacent beams simultaneously blocked longer than 80mS trigger conditions can effectively identify the object size, to prevent false alarms caused by small animals crossing; 7, ≤ ± 4 ° degrees AF circuit, sound and light calibration tips, adjustable angle of 180 °. Guangzhou Yi Li Fu Electronic Technology Co., Ltd., the production of a variety of anti-theft alarm equipment research and development, quality and price concessions. ALEPH infrared detector can identify the size of the object grating, to prevent false alarms caused by small animals activities; are widely used in windows and doors, passageways, outside the building or wall, the effective detection of the illegal invasion, is an important area of ??current security products . One difference with the common security grating photoelectric sensor is its design, this design concept is called "control reliability." Reliability is one of the standard application control security aspects related to the US Occupational Safety and Health Department (OSHA) and American National Standards Institute (ANSI) as required. American National Standards Institute document B11.19-2003, Chapter 3, Article 14, the reliability of the control is defined as "a set of machine control systems and safety devices, the control unit, connected to the relevant interface can affect their safety When a fault occurs, the ability to achieve the security situation. " Unlike photoelectric sensors, safety grating with self-test function to monitor internal fault grating system. Once inside fails, the system will immediately send the target machine's emergency stop signal. Then enter shutdown mode raster only when defective parts are replaced, and properly reset operation, the grating will allow a restart mode, the output signal of the redundant safety Another common scenario is when a security self.
