Open Reed Switch | 11mm Plastic Body | GPS-11A Anti-Interference

The GPS-11A reed switch is a magnetic control switch inside a plastic shell. It's normally open, meaning the circuit is off until a magnet is nearby. This 50-piece lot is good for anyone needing a dependable, non-contact switch for their electronics projects. Features and Benefits - Normally Open (SPST) operation - The switch stays off by default. This saves power in devices that run on batteries. - Plastic encapsulated body - The 3x11mm reed switch is safe from physical damage and some electrical interference. - Magnetic activation - It switches without contact. This means no mechanical parts wear out. - 10W power rating - It can switch loads up to 10W at 100VDC. This works for many low-power circuits. Applications - Build alarm sensors for doors and windows. They trigger when a magnet moves away. - Add position detection to projects. For example, confirm a robotic arm is back in its home spot. - Create simple triggers for interactive displays, puzzles, or toys that react to a magnetic wand. What It Is This product is a Normally Open Reed Switch, model GPS-11A, featuring an 11mm plastic body. It operates as a magnetic proximity sensor, designed with an anti-interference feature. Reed switches are a type of proximity sensor that detect the presence of a magnetic field. When a magnet comes close, the internal contacts of this switch will close, completing an electrical circuit. This specific offering includes 50 pieces. Key Uses & Applications These 11mm plastic body reed switches are suitable for various applications requiring magnetic sensing and anti-interference properties. As a Normally Open switch, it is ideal for systems where a circuit needs to be completed upon the detection of a magnet. Common uses include position sensing in industrial sensor setups, safety interlocks, and as an electronics module in custom projects. The anti-interference feature makes it reliable in environments with electrical noise. How to Choose When selecting a proximity sensor, consider the sensing theory required; this product uses magnetic sensing. For applications needing a compact, durable solution, the 11mm plastic body is a key specification. The Normally Open switch type is crucial for systems where a signal is generated upon magnetic presence. To test a proximity sensor like this, simply bring a magnet near its body; a multimeter can then confirm the circuit closure. Evaluate if the anti-interference feature is necessary for your operational environment.
