As a commonly used industrial automation equipment, proximity switch plays an important role in many fields. However, sometimes we may encounter a situation where the proximity switch is burned out. So, what are the reasons for the proximity switch being burned out? Let’s introduce it to you below.

1. Overload

Proximity switches usually need to be used within a certain current range. If the load current exceeds the rated current of the proximity switch, it will cause the proximity switch to overload and burn out.

2. Short circuit

If the output circuit of the proximity switch is short-circuited, the current will suddenly increase, exceeding the rated current of the proximity switch, causing the proximity switch to burn out.

3. External environment

Proximity switches are often used in harsh working environments. If there are corrosive gases, dust and other substances in the environment, the internal components of the proximity switch will be damaged, resulting in burnout.

4. Improper operation

Improper operation is also one of the reasons why the proximity switch is burned out. For example, improper installation, improper use, improper maintenance and so on.

In order to avoid the proximity switch being burned out, we need to pay attention to the following points:

First, when using a proximity switch, be careful that the load current does not exceed the rated current range of the proximity switch. If the current is too large, you should promptly consider replacing the appropriate proximity switch.

Secondly, make sure there is no short circuit in the output circuit of the proximity switch. When installing or repairing the proximity switch, be sure to carefully check the control loop to ensure that the circuit is in normal condition.

In addition, the usage environment of the proximity switch also requires special attention. If the working environment is harsh, corresponding protective measures should be taken to avoid damage to the proximity switch by corrosive gases, dust and other substances.

Finally, pay attention to the correct operation of the proximity switch. During installation and use, follow the operating instructions to avoid burning the proximity switch due to improper operation.

In short, understanding the reasons why the proximity switch burns out is very important for us to use and maintain the proximity switch correctly. Only by understanding the cause of the burnout can corresponding measures be taken to avoid burnout of the proximity switch and improve the service life and stability of the equipment.
