Short circuit protection: When the load is short-circuited or there is a problem, it not only protects itself but also protects the load from being burnt out.
Overload protection: Automatic protection when the load is unstable or the current becomes large due to problems.
Reverse polarity protection: Reverse connection of the positive and negative poles of the product power cord will not burn the product.
In general, the photoelectric sensor has three parts, which are divided into: transmitter, receiver and detection circuit. The photoelectric detection method has the advantages of high accuracy, fast response, non-contact, etc., and has many measurable parameters. The sensor has a simple structure and flexible forms. Therefore, photoelectric sensors are widely used in detection and control.
