Hall Effect Sensor NJK-5002C | NPN Magnetic Proximity Switch

The NJK-5002C is a hall effect proximity sensor that finds magnetic objects without touching them. This magnetic sensor has an NPN normally open output. It switches when a magnet is within 10 mm. It's a good choice for automation jobs that need to sense position. Features and Benefits - 10 mm detection distance - It senses magnets from a useful distance, giving flexibility in machine design. - M12 threaded metal body - You can mount it easily and securely in standard brackets and panels. - NPN Normally Open (NO) output - It connects well with most PLCs and microcontroller inputs like Arduino. - Built-in LED indicator - It lights up red when it finds an object, making setup and system checks easier. Applications - Check if a machine's safety gate is open or closed. - Count metal parts on a production line by putting a small magnet on each one. - Use as a non-contact limit switch for a CNC router or 3D printer's moving parts. What It Is This NJK-5002C proximity sensor detects the presence of nearby objects without physical contact. It operates by generating an electromagnetic field or beam of radiation and looking for changes in the return signal. As a magnetic sensor with an NPN output, it is suitable for integration into various automation systems. It functions safely below 50Vac or 75Vdc, making it a reliable electronics module for industrial applications. Key Uses & Applications The NJK-5002C NPN Output proximity switch is ideal for automation tasks requiring non-contact detection. Common applications include: - Position sensing in machinery. - Counting objects on a conveyor belt. - Detecting the presence of metallic parts. - Limit switching in automated processes. Its magnetic sensor type makes it particularly effective for ferrous material detection. When considering how to test proximity sensor function, simply introduce a suitable target object within its sensing range and observe the NPN output signal change. How to Choose When selecting a proximity sensor, consider the specific requirements of your automation project. This particular barrel sensor, available in models NJK-5002C, NJK-5002A, NJK-5002B, and NJK-5002D, features an NPN output. Ensure your control system is compatible with NPN output types. For applications where the target material is non-ferrous, an optical sensor might be more suitable, but for magnetic detection, this industrial sensor is a strong choice. Always verify the voltage requirements, which for this model are below 50Vac or 75Vdc.
