Magnetic Sensor | GPS-01A/B Magnetron | Normally Open/Closed

This pack of GPS-01 reed switches gives you a dependable magnetic sensor for your electronics work. Each cylindrical reed switch acts as a magnetic control switch. It turns on when a magnetic field is near. This set includes sizes from 4x18mm to 6x38mm for different uses. Features and Benefits - Includes NO and NC types - A normally open reed switch connects a circuit near a magnet. A normally closed one breaks it. This gives you control. - Glass-covered contacts - The sealed design keeps the switch parts clean. This makes it a reliable magnetic sensor for security systems. - Low power use - It uses almost no power when not active. This is good for battery-powered devices, like a remote GPS reed switch for a door alarm. - Simple operating idea - The switch has two reeds. A magnet pulls them together or pushes them apart. This is a direct way to sense presence. Applications - Alarm Systems - It's a key part for wired magnetic reed switch alarm systems. Use it on entry points like doors, gates, and cabinets. - Industrial Automation - Use the reed switch sensor to count wheel rotations. Or track items on a conveyor belt. - Robotics - Detect when a robotic arm reaches its limit. Or confirm that a gripper is fully closed. What It Is This product is a magnetic proximity sensor, specifically a reed switch, available in a Normally Open (NO) or Normally Closed (NC) configuration. It functions as an inductance sensor, detecting the presence of a magnetic field without physical contact. The GPS-01A/B model is an electronics module designed for reliable sensing in various applications. Its compact dimensions range from 4x18mm to 6x38mm, making it suitable for integration into diverse systems where space may be limited. Key Uses & Applications Magnetic proximity sensors like the GPS-01A/B are widely used in industrial settings for automation and control. They can detect the position of moving parts, count objects, or act as limit switches. Common applications include door and window security systems, liquid level sensing, and in machinery to monitor the status of components. As a non-contact sensor, it is ideal for environments where dust, dirt, or moisture would affect traditional mechanical switches. How to Choose When selecting a magnetic sensor, consider the required switch type, either Normally Open (NO) or Normally Closed (NC), based on your circuit design. Evaluate the physical dimensions needed for your application, with options from 4x18mm up to 6x38mm. The theory of operation, an inductance sensor, should align with the magnetic field you intend to detect. To test a proximity sensor, you can typically use a multimeter to check for continuity changes when a magnet is brought into proximity.
