Question
Why can't AC 2-Wire Proximity Sensors switch the Timers power supply?
Answer
Countermeasure
Instead of using Proximity Sensors, use Relays such as MY2N-CR General Purpose Relays to switch Timers power supply. (Pay careful attention to the contact capacity.)
Probable Cause 2
The Sensors output may have been damaged due to Timers inrush current when the power was turned ON.
