M24 Capacitive Proximity Sensor, PNP/NPN, 2 Wire

In a parallel connection, the sensors operate in an OR configuration, meaning the load is activated when any one of the proximity sensors operates. NPN and PNP types cannot be mixed in this setup. The number of sensors that can be connected depends on their total leakage current—more sensors can be added as long as the leakage current does not affect proper load operation.

In a series connection, the sensors work in an AND configuration, meaning the load is activated only when all proximity sensors operate simultaneously. The number of sensors that can be used depends on the total saturation voltage of the sensors, and additional sensors can be added as long as the combined voltage drop does not interfere with the power supply voltage.

When sensors are connected in series, the overall response frequency is affected by the cumulative reset time of each sensor. As more sensors are added, the combined response time increases, which may reduce the speed at which the system can react.
