10. 9 Sensors and Switches... #5 Control Interface: AC Considerations l Leakage Current –2 Wire AC proxes have a small amount of current flowing even when the sensor is not actuated. –This current can cause some PLCs to indicate the prox is actuated when it is not, or, to not turn off after the target has left the face of the prox. –Typical specification for most PLCs is < 2.0 mA. Reality says < 1.7 mA.
