When choosing a light curtain safety device model, there are several parameters needed, so how do you distinguish the protection height and the protection distance when choosing the safety light curtain sensor?
The formula for calculating the protection height is: (number of optical axes-1) * optical axis spacing. The protection distance refers to the distance between the light curtain transmitter and the receiver, which is also called the distance of the beam.
What is the role of the projector in the laser curtain sensor?
Light curtain sensor is also known as light curtain safety device (also known as infrared safety light curtain, punch protector, infrared safety protection device, etc.). In modern factories, humans and machines work together on some potentially dangerous mechanical equipment, such as Stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, mechanical transmission and handling equipment, and hazardous areas (toxic, high pressure, high temperature, etc.) are likely to cause personal injury to operators.

Ir light curtain is widely used in presses, hydraulic presses, hydraulic presses, shears, automatic doors and other large machinery or dangerous situations requiring long-distance protection.
20mm optical axis spacing is generally used to protect the palm. When the distance is relatively close to the dangerous area, the possibility of danger cannot be ignored. If the remote sensing length infrared laser safety light curtain sensor safety light barrier is used to protect the palm, Then the optical axis spacing of 20mm is sufficient, such as the safety protection of personnel on the shearing machine.
