Magnetic Sensor | Normally Open/Closed Switch | 2-Piece Set

This mounted reed switch is a simple magnetic sensor that detects position without touching. It comes with a sealed switch and a separate magnet. The switch activates when the magnet comes close. You can pick either a Normally Open or Normally Closed version for your circuit. Features and Benefits - Normally Open (NO) or Closed (NC) - The NO type completes a circuit when the magnet is near; the NC type breaks it. - Sealed cylindrical housing - Its plastic body protects the switch inside from dust, moisture, and outdoor weather. - Simple two-wire connection - It connects easily into your circuit, making it suitable for door alarms or limit switches. - Screw-mount design - Each piece has tabs with holes, so you can attach the sensor and magnet firmly to any flat surface. Applications - Home security systems for knowing when doors or windows open. - Industrial settings for sensing the position of air cylinders or machine guards. - Cabinet and display lighting to turn lights on automatically when a door opens. What It Is This is a 2-piece set of cylindrical magnetic sensors, specifically reed proximity switches. They are designed for electrical DIY supplies and feature a plastic housing. These sensors operate as either Normally Open or Normally Closed switches, offering flexibility for various electrical circuits. As a proximity sensor, it detects the presence or absence of a magnetic field without physical contact. Key Uses & Applications These magnetic sensors are suitable for a range of electrical DIY projects. Their Normally Open or Normally Closed operation allows for diverse applications in control systems, such as detecting door closures, window positions, or the presence of moving parts in machinery. As a type of industrial sensor, they can be integrated into systems requiring reliable, non-contact switching. Their cylindrical mounting simplifies installation in many setups. How to Choose When selecting a proximity sensor, consider the required operation: Normally Open or Normally Closed. This 2-piece set offers both options. For testing a proximity sensor, a simple multimeter can be used to check continuity when a magnet is brought near, confirming its switching action. Consider the housing material for durability; this product features a plastic housing. For applications requiring specific detection distances, note that magnetic sensors typically operate within a few centimetres, unlike optical sensors which can have a larger range.
