In addition to a “four-chemical emitting element” which suppresses changes in the light emitting element over time so that a stable level of light emission can be maintained over long periods, a “APC (Auto Power Control) circuit” has also been adopted afresh.
The light emitting amount can be controlled in minute degrees so that even changes occurring over very short periods can be handled, allowing stable sensing performance by suppressing deviations in light emitting amounts caused by changes in the ambient environment that could not previously be suppressed.

■Stable sensing comparison

If the light receiving level becomes saturated during close-range sensing or when sensing transparent or minute objects, you can adjust the light emitting amount of the sensor to stabilize sensing without needing to change the response time. Sensing that previously required the response time or fibers to be changed can now be set much more easily using this function.
