Tips: Parallel and series connection of proximity sensor
Parallel connection: OR connection, NPN and PNP type can't be used in combination. Parallel proximity sensors are in OR connection. The load can be driven once any one of proximity sensors is operating. The number of proximity sensor depends on the sum of leakage current. As long as it does not affect the load operation, more proximity sensors can be connected.
Series connection: When proximity sensors are in AND connection, the load can be driven by all the proximity sensors operation. The number of proximity sensors depends on the sum of their saturation voltages. As long as it does not affect the voltage of power supply, more proximity sensors can be connected. The response frequency of proximity sensor is the accumulation of initial reset of each proximity sensor.
