Tips: What is a square inductive proximity switch?

A square inductive proximity switch is a type of sensor used in industrial automation to detect the presence or absence of metallic objects without physical contact. This switch operates based on the principles of electromagnetic induction. The sensor typically has a square or rectangular shape and is made of a durable material suitable for industrial environments.

Inside the square inductive proximity switch, there is a coil that generates an electromagnetic field when an electrical current passes through it. When a metallic object enters the sensing range of the switch, it induces eddy currents in the metal, causing a change in the electromagnetic field. This change is detected by the sensor, triggering the switch to either open or close an electrical circuit. These switches are commonly used for tasks such as object detection, positioning, and automation in various industries due to their reliability, durability, and ability to function in harsh conditions.
