Magnetic Contact Switch Sensor for Arduino

This magnetic switch, also known as a reed switch, has two magnetic reeds mainly made of iron and nickel, neatly sealed in a plastic case. The reeds overlap with a tiny gap. When an appropriate external magnetic field gets within 2cm, they touch and conduct, detecting object position changes easily. It's a great choice for miniaturized devices due to its compact design and light weight, fitting well in limited spaces. The switching elements are hermetically sealed in an inert gas, keeping them away from the external environment and giving it a long service life. With a wide voltage operating range from 0 to 100V, this switch can be used in various applications like door/window limiters, proximity switches, measuring instruments, automation/security/transportation equipment, and smart homes. **Features** - Compact and lightweight - Long - lasting performance - Wide voltage operation **Specification** - Operating Voltage: 0~100V - Operating Principle: magnetic sensor - Output Signal: switching value signal - Size: 6x20x350mm/0.24*0.79*13.78” - Color: black **Documents** - Product wiki **Shipping List** - Magnetic Switch x1 - Sensor Adapter x1 - Sensor Data Cable x1

Using this magnetic contact switch sensor is easy. First, find a suitable spot in your Arduino project. The switch is compact and light, so it can fit in small spaces. Connect the sensor adapter and the data cable as shown in the product documentation. Then, when an external magnetic field comes within 2cm of the switch, it will detect the change and conduct electricity. When using it, make sure the operating voltage is within the 0 - 100V range. Avoid exposing the switch to extreme temperatures or harsh chemicals, as this may affect its performance and shorten its service life. For maintenance, keep the switch clean and dry. Check the connections regularly to ensure they are secure. If you have any problems, refer to the product wiki for more information.
