Homing sensor Y not triggering alarm

I installed the inductive sensors and the Y sensor does not trigger an alarm in gsender. It lights up when touched with a metal wrench but gsender does nothing. I switched the sensors around to test them and they all work in the x or z position but none work in the z position although they do light up the led on the sensor. I have tried gsender 1.1.4, 1.1.6 and 1.1.7 to no avail. I looked at the pins and they are all there and straight.

Any help is appreciated.
