A：
The through-beam light curtain, also known as an infrared light curtain, light curtain, or photoelectric protection device, is widely used in industrial production.
The working principle of a through-beam light curtain is as follows: The emitter emits light, which is received by the receiver, forming a beam of light. The internal circuit processes the ON/OFF status of the beam to trigger actions as stopping the equipment or issuing a safety alert.
Through-beam light curtains find applications in various fields including punch presses, shearing equipment, metal cutting devices, industrial robots, injection molding machines, filter presses, automated welding lines, and automated assembly lines.
Characteristics of the photoelectric grating: It has a compact design, making it convenient for transportation and installation. It offers various installation methods, providing flexibility and convenience. The photoelectric grating has a self-checking function, ensuring higher safety. It also has the ability to resist water, light interference, and magnetic interference.
Some general parameters include a protection height ranging from 30-2000mm, beam pitch options of 10mm, 20mm, 40mm, etc., protection distance ranging from 0-2000mm, response time less than 10mm, and a through-beam configuration. The casing is rated IP65 for protection.
In industrial production, the use of photoelectric gratings can effectively prevent safety accidents, eliminate risks for operators and third parties, reduce accident costs, improve company productivity, protect employee safety, and promote stable company development.
