Reed Switch | Proximity Sensor for Control | GPS-01B Series | NO/NC 4x18mm-6x38mm

This GPS-01 reed switch is a basic magnetic sensor. It detects nearby objects. It works by opening or closing an electrical circuit with a magnet, no physical contact needed. This package has different sizes and types (NO/NC) for various projects, from security to automation. Features and Benefits - Normally Open (NO) and Normally Closed (NC) options - You choose if the circuit connects or disconnects when a magnet is close, matching your project's needs. - Sealed glass body - Keeps the internal contacts safe from dust and moisture. This helps it work consistently over time. - Several sizes included - You get common cylindrical reed switch sizes like 4x18mm and 5x15mm. They fit into different housings. - Simple two-wire hookup - This magnetic control switch is easy to add to new or existing wired alarm systems. Applications - Home Security - Make a magnetic reed switch for a security system. It will tell you when doors or windows open. - Position Sensing - Use it as a magnetic proximity sensor. It can confirm a machine guard is shut or a part is in place. - DIY Projects - Build a simple liquid level sensor for a tank. Just attach a magnet to a float. What It Is This is a GPS-01B Series magnetic control proximity sensor, supplied in packs of five. It is designed for proximity control applications. This sensor operates with a Normally Open/Closed (NO/NC) switching action. It can handle a maximum switching voltage of 200V and a maximum switching current of 0.5A. The contact rating is 10W maximum. These industrial sensors come in various dimensions, including 4x18mm, 5x15mm, 20mm, 25mm, 6x30mm, and 38mm. Key Uses & Applications Proximity sensors like the GPS-01B Series are commonly used for detecting the presence or absence of objects without physical contact. They are vital in automation and control systems where reliable object detection is needed. For example, they can be used to monitor the position of components on an assembly line or to trigger an action when an object enters a specific range. Their various dimensions make them suitable for integration into different machinery and electronics modules. How to Choose When selecting a proximity sensor, consider the required switching action (NO/NC) and the maximum voltage and current ratings for your application. This GPS-01B series offers a 200V maximum switching voltage and 0.5A maximum switching current. Its contact rating is 10W maximum. Dimensions are critical for fitting the sensor into your setup, with options like 4x18mm, 5x15mm, and 6x30mm available. To test a proximity sensor, apply power and check its switching behaviour with a ferrous object.
