Sensor Alternative | Magnetic Reed Proximity Switch | Normally Open

This GPS-01 reed switch is a simple magnetic proximity sensor. It's a normally open (NO) switch, meaning the circuit is incomplete until a magnet comes near. When the magnet is close, two internal reeds touch and close the circuit. It's available in several miniature sizes, including 4x18mm. Features and Benefits - Normally Open Contact - The circuit closes only when a magnet is present. This is useful for alarms or counters that need to register an event. - Hermetically Sealed Glass Tube - Internal contacts are protected from dust, moisture, and corrosion. This lets the reed switch work in tough environments. - No Power Needed When Open - The switch is passive. It doesn't draw current in its resting state. This helps create low-power circuits for security applications. - Multiple Sizes Available - You can choose the right size for your project. Options range from a small 4x18mm switch for compact electronics to a larger one for automotive uses. Applications - Security Systems - Use it as a door window reed switch for a straightforward alarm trigger. The sensor can detect a magnet through non-ferrous materials like plastic, wood, or aluminum. - Position Sensing - Install a 4x18mm reed switch to detect the end-of-travel position for a robotic arm or 3D printer bed. Wiring is simple; just connect it in series. - Fluid Level Detection - Attach a magnet to a float inside a tank. This GPS reed switch can then detect high or low levels for pumps or indicators. What It Is This Magnetic Reed Proximity Switch is a sensor alternative designed for various industrial and electronic applications. It operates in a Normally Open mode, meaning the circuit is open until a magnetic field is detected. The sensor itself is a reed switch, encased in either glass or metal, depending on the specific dimension. It functions as a magnetron proximity sensor, detecting the presence of a magnetic field without physical contact. Key Uses & Applications This proximity sensor is ideal for applications requiring non-contact detection. Its Normally Open operation makes it suitable for triggering events when a magnetic field is present. Common uses include position sensing, door and window alarms, level sensing, and security systems. As a reed switch, it provides a reliable and simple method for detecting proximity in various industrial sensor setups. Its small dimensions, ranging from 4x18mm to 6x30mm, allow for integration into compact electronics modules. How to Choose When selecting this Magnetic Reed Proximity Switch, consider the required dimensions for your application. Available sizes include 4x18mm, 5x25mm, 6x20mm, 6x25mm, and 6x30mm. The choice of glass or metal material will depend on the environmental conditions and durability requirements. To test a proximity sensor like this, simply bring a magnet near the switch; in its Normally Open state, the circuit should close upon detection of the magnetic field. This type of industrial sensor is a native sensor, relying on the magnetic field for its operation.
