Magnetic Hall Effect Sensor | NPN Normally Open Proximity Switch

This square magnetic sensor detects positions without touching anything. It's for industrial automation. It uses a Hall effect sensor that turns on when a magnet gets close. This magnetic switch comes in NPN and PNP 3-wire models. You can choose the one that fits your control system. Features and Benefits - NPN or PNP Output - Pick the setup you need. NPN sensors connect the output to ground. PNP sensors connect the output to the positive power supply. - 25mm Detection Range - It senses the magnet from up to 25mm away. This gives you flexibility for where you mount it and how you line it up. - IP67 Environmental Sealing - The housing keeps out all dust. It can also handle being underwater for a short time. This means it works in tough conditions. - Normally Open Operation - This switch makes a circuit only when a magnet is nearby. This is a common way to signal that something is 'true' or 'present'. Applications - Machine Safety: Put it on a safety gate or machine guard. It makes sure the gate is closed before the machine can run. - Cylinder Position Sensing: Attach it to a pneumatic or hydraulic cylinder. It tells you when the piston has reached the end of its movement. - Conveyor Systems: Use it to count items, check package positions, or activate diverter gates on an automated line. What It Is This is a magnetic proximity sensor, also known as a Hall Effect proximity switch. It is an electronics module designed to detect the presence of magnetic fields without physical contact. The sensor operates on the Hall Effect principle, generating an NPN Normally Open output when a magnetic field is detected. It is suitable for low voltage applications, functioning safely below 50Vac or 75Vdc. This type of industrial sensor is typically housed in a barrel sensor form factor, offering robust performance in various settings. Key Uses & Applications Magnetic proximity sensors are versatile industrial sensors used for non-contact detection. This NPN Normally Open Hall Effect switch is ideal for applications requiring precise position sensing or counting. For instance, it can detect the opening or closing of doors, monitor the rotation of machinery parts by sensing magnets attached to them, or act as a time sensor for automated processes. Its robust design makes it suitable for environments where dust or moisture might interfere with optical sensors, providing reliable operation up to its detection range. How to Choose When selecting a magnetic proximity sensor, consider the detection principle and output type. This specific model uses the Hall Effect and provides an NPN Normally Open output, which means the output is open (off) in the absence of a magnetic field and closes (on) when a magnetic field is detected. Verify the required voltage, ensuring it falls below 50Vac or 75Vdc for this unit. To test a proximity sensor, apply the specified voltage and bring a magnet within its detection range; the output should change state. Compare the barrel sensor form factor with your installation requirements.
