Principles and applications of the safety light curtain 2017-8-26

Safety light curtain principle by infrared light emitting diodes to emit multiple beams of light onto a receiver to form a curtain of infrared light, and if the body part through the screens, and blocking the beam of light which, at least, through the internal control circuit, the machine being monitored issued an emergency brake signal such as press, press and so on.

Curtain has a very wide range of applications, such as on the need to constantly send reclaimer stamping equipment, if you install security door contact, you need to frequently switch operator protective door, it will not only increase the workload of the operator, but also reduces production efficiency. In this case, the use of the grating and the light curtain is the best choice. When the operator to send reclaimers, as long as there is any part of the body blocking the light, it will cause the machine into a safe state without an operator will bring harm.

Beam density determines how much how much volume was only part of the body is detected by the light curtain. Ergonomically data should be less than the diameter of an adult's finger 14mm, palm thickness not less than 30mm, wrist diameter less than 40mm, for example: if the distance between the optical axis of the light curtain is using 40mm, axis diameter 20mm, its resolution is 40 + 20 = 60mm, then the hand value, palms, wrists and arms are likely through the light curtain will not be found. So, if you want to get higher security, they need to use higher resolution screens, security screens Albert curtain products applicable to the pipeline, elevators, paper machinery, leather machinery, woodworking machinery, mechanical presses, safety testing of hydraulic presses, Asian film machines, cutting machines, bending machines, injection molding machines, industrial robots, packaging equipment, parking, industrial automation equipment, restricted and dangerous areas, etc., can be reliably protected object security.
