FAQ

Question?
What is the difference between a “light-ON” (hellschaltend) and “dark-ON” (dunkelschaltend) sensor?

Answer: A light-ON sensor, like this 3RG7012-7AB01, activates its output when the light beam is received (i.e., when an object reflects the light back to the sensor). A dark-ON sensor activates its output when the light beam is interrupted. The choice depends on the application’s logic and fail-safe requirements.

Question?
Can this sensor be used for detecting transparent or highly reflective objects?

Answer: As a standard diffuse photoelectric sensor, it may have difficulty reliably detecting transparent objects. For highly reflective or shiny objects, care must be taken with the mounting angle to avoid false signals. For such applications, a sensor with background suppression or a retro-reflective sensor is often a better choice.

Question?
What does the “surplus light emission” (Funktionsreserve) LED indicate on this sensor?

Answer: The green LED for surplus light emission indicates the signal strength. A solid green light means the sensor is receiving a strong, reliable signal, well above the switching threshold. This is useful during setup to ensure reliable operation, especially if dust or dirt accumulation is expected.
