Magnetic sensors are the measurement instruments used to detect and measure the strength of a magnetic field. One type of magnetic sensor is a switch, also known as solid-state or a digital switch. The SW353RT magnetic switch is a popular switch which is renowned for its durability and simplicity. It uses a reed switch to detect the presence or absence of a magnetic field, and is often found in applications such as carpentry, metalworking, and medical settings. Its ability to operate in hazardous conditions makes it an invaluable tool for many critical fields.

The SW353RT is a solid-state switch consisting of two major parts: the switch, which contains a coil of magnetically sensitive wire, and the contact, comprising a wire connected to a second coil. The two parts are linked via an electrical contact. When a magnetic field is present, the contact will close, allowing the switch to function. Conversely, when a magnetic field is absent, the contact will open, disabling the switch.

The primary use of the SW353RT magnetic switch is to detect the presence or absence of a magnetic field when it passes through the wire coil. This is done by measuring the changes in the electrical current passing through the coil. By connecting the switch to an external device, such as a timer or indicator light, the user can detect whether or not a magnet is present. The SW353RT is also typically used as a safety switch, preventing the user from operating a machine when the presence of a magnet is not detected.

The SW353RT can be used in a variety of applications, such as door alarms, vending machines, medical equipment, security systems, and circuit breakers. It is compact and durable, making it a great choice for harsh environments. Additionally, it is easily adaptable to its environment and does not require complex installation or set up. It is also known for its low power consumption, making it a great choice for battery-powered operations.

The SW353RT is most often used in combination with a reed switch. A reed switch is a type of electrical switch that uses a magnetized metal core to turn electricity on and off. The reed switch is installed alongside the SW353RT and when the magnetic field changes, the reed switch will close, sending an electrical signal to the SW353RT. The signal will then trigger the SW353RT to close its contact, enabling or disabling a device.

The SW353RT is a suitable option for applications where a reliable indication of the magnetic field’s presence or absence is essential. Its low profile, low power consumption, and high reliability make it a great choice for medical, security, and industrial settings. Its compact size allows for it to be mounted in tight areas. It is also EMC immune, meaning it is not affected by electromagnetic interference, and is UL approved, ensuring its safety and stability.
