When a metallic object enters this field, it causes a change in oscillation, triggering the sensor.What does N.O. PNP output mean?N.O. (Normally Open) PNP output signifies that the sensor's output is open in its normal state and closes when a target is detected, allowing current to flow from the sensor to the load. In a PNP configuration, the sensor provides a positive voltage to the load.What is the benefit of a Micro QD connector?A Micro QD (Quick Disconnect) connector simplifies and speeds up installation and replacement of the sensor. This design significantly reduces downtime during maintenance or when swapping sensors, improving operational efficiency.
