Need some help. This is how my setup is currently. NPN prox. I want to actuate the solenoid. In this configuration, I can put detectable object near the sensor, the light blinks on, nothing happens. To test, I connect the multimeter, red lead to sensor signal, black to ground. My belief is if no object near sensor, reading should be 0v. Object near sensor, 12v, sensor is NO. But, in my case, reading is 12v with no object, and with object, just over 11v. So now I'm confused what happening. It never does actuate the solenoid. What am I doing wrong here?
