Tips: How to choose the models of inductive ring proximity sensor?

1. When choosing the model, you can choose according to your own host computer or the connected load. The output mode of the ring proximity switch of some manufacturers also has NPN/NO.NC optional or dual output, or PNP/NO.NC optional or dual output, each with its own characteristics. As for the output voltage signal, the output will be as much as the input (floating around 1V).

2. Regarding the size of the circular hole of the ring proximity switch, there are generally 3-25mm sizes available on the market. You can choose according to the size of your own detection object. If the detection object is small, you should choose a small detection hole. The object can also be used with other tools during detection. In short, the selected circular hole should match the object to be detected, so as to ensure the sensitivity and stability of the detection.

In this video, ATO will show you the differences between inductive and magnetic types.

Change the PNP (NPN) proximity sensor to NPN (PNP)

The polarity of the proximity sensor has two types, PNP and NPN. We show you how to change the PNP (NPN) type proximity sensor to the NPN (PNP) type.

2-wire AC proximity switch/sensor wiring

We have proximity switches with a diameter of 4mm~30mm, applicable voltages are 24V DC/120V AC/240V AC, which can detect metal and non-metal objects.

Ring sensor information

I need three PNP normally open ring sensors with a 15mm diameter sensing hole and the ability to maintain the switch logic state as long as the metal shaft remains in the sensing hole. I do not need to count objects, I only need to detect the state of objects in the sensing hole.
