A diffused mode photoelectric background suppression sensor employs different sensing components to distinguish between objects that are close to one another without picking up background noise.
It can work at a variety of distances, with its sensing range for black targets being only 5% smaller than its range for white targets. Visible red has the apparent advantage of making alignment between the photoelectric sensor and the target easier.
This visual help is removed when using an IR light source, but its higher power and superior colour insensitivity are its advantages. Infrared has a stronger optical power output and can function at longer detection ranges than visible red because it is more efficient and can be driven by larger current pulses.
The Global Background suppression sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
High background suppression performance is provided by Bulletin 42BC Long-range Background Suppression Sensors from Rockwell Automation at sensing ranges up to 2 m. (6.6 ft).
This sensing capability is appropriate for applications where traditional transmitted beam or retro-reflective sensing is impractical because both sides of the target are difficult to access or when cost is a significant consideration.
A steel right angle mounting bracket that offers several mounting possibilities is included with every Bulletin 42BC. The sensor must be placed so that the target passes in one of the following directions due to the detecting mechanism. Upward and downward motion cannot be observed.
