Safety light curtain detection distance

How do optical gratings achieve safety protection? Safety optical gratings act like invisible guardians, constructing a protective net through infrared beams. When an object blocks the beam, the grating triggers a shutdown within 0.02 seconds. The beam range depends on the optical axis spacing (typically 10-30mm) and the number of effective beams (4-32 beams). Common detection distances range from 0.5 meters to 20 meters, meeting the needs of various scenarios.

 

What factors affect detection distance?
Ambient light: Strong light may interfere with infrared reception.

 

Installation angle: A deviation of more than 5° will shorten the effective distance by 30%.

 

Specular reflection: Smooth surfaces may cause beam refraction.

 

Contamination level: Dust accumulation will reduce the maximum detection distance by 20%.

 

The art of matching distance with the scenario:

Precision machining areas: Select 0.5-2 meter short-pitch high-density optical gratings (beam spacing ≤20mm).

 

Logistics sorting lines: Suitable for 3-5 meter medium-pitch optical gratings, balancing protection and efficiency.

 

Large stamping equipment: Requires long-pitch models of 15 meters or more, working in conjunction with multiple sets simultaneously.
