Reed Switch | 35cm Tube Length | Normally Open/Closed Contact

This magnetic reed switch senses when a magnet is nearby. It either closes or opens an electrical circuit. This lets you detect position without parts touching. This model has a 35cm cable. You can get it in Normally Open or Normally Closed versions. Features and Benefits - Sealed Glass Tube - The internal parts are protected from dust and moisture. This makes it work well in industrial settings. - No Contact Needed - The switch works with a magnetic field. No moving parts means nothing wears out over time. - NO and NC Options - Choose Normally Open (NO) to complete a circuit when a magnet is there. Choose Normally Closed (NC) to break it. - 2-Wire Design - This 2-wire sensor connects easily to 12V systems, microcontrollers, or alarm panels. Applications - Security Systems - Install it on a door or window. It will trigger an alert if the opening is moved. - Robotics and Machinery - Use it to tell when a robotic arm reaches its limit or when a safety guard is closed. - DIY Electronics - Put this small sensor into projects. It can tell when a lid closes or a part returns to its spot. What It Is This product is a Reed Switch, a type of magnetic proximity sensor. It is available in quantities of 2 or 5 pieces. The Reed Switch functions as an electronics module, detecting the presence of a magnetic field without physical contact. This particular model, the Hongqichip GPS-01 GPS-23 GPS-30, features a reed tube length of 35 cm. It is designed with a Normally Open/Closed switch type, meaning its electrical contact state changes when a magnet is brought near. Key Uses & Applications Reed switches like this magnetic proximity sensor are integral industrial sensors for various applications. They are commonly used in security systems for door and window sensors, acting as native sensors to detect opening and closing. Other uses include position sensing in automation, flow sensing in liquids, and level detection in tanks. Their non-contact operation ensures durability and reliability in environments where physical contact sensors might wear out. The 35 cm tube length offers flexibility for installation in different setups. How to Choose When selecting a Reed Switch proximity sensor, consider the required quantity, either 2 or 5 pieces. The 35 cm reed tube length is a key specification for fitting into your application. As a magnetic proximity switch, it works by detecting a magnetic field; therefore, the presence of a suitable magnet in your setup is essential. To test a proximity sensor like this, you typically introduce a magnet to its sensing area and observe the change in its electrical state, usually with a multimeter. Ensure the Normally Open/Closed contact type suits your circuit's requirements.
