I'm having trouble with one of the sensors that control the high level of the blade. It is in position and at a distance of 2 millimeters which is in the acceptable range. The sensor stops doing its job seasonally, is disassembled and tapped a few times and when it is reassembled, it starts working for a while longer. I can deduce that it is a two-wire inductive proximity sensor, and it has a detection range of 2 millimeters to 4 millimeters, but I would like to know if that sensor is of the NPN or PNP type... does anyone have that information that you can share with me? Also that guillotine is missing the bulb, checking I could see that it is elongated of about 80 millimeters, halogen type and reaches 240 Vac at its bases. But I'm not sure what wattage is, I think it's 100 W. Is that the right power?

Thank you for your feedback.
 
I got some pictures of the sensors.
