3-Wire Magnetic Sensor | M12 NPN NO | 2mm Detection Distance 6-36V

This OMCH inductive proximity sensor works as a non-contact metal detector in industrial places. It creates a small electromagnetic field. This lets it sense both magnetic and non-magnetic metals without touching them. You can get models that detect from 2mm up to 10mm away. Features and Benefits - Multiple body sizes (M8, M12, M18, M30) - Pick the thread size and detection range that fits your machine and available space. - NPN and PNP output options - Available in NPN (sinking) and PNP (sourcing) logic. These match what your control system needs. - Integrated LED status indicator - A light on the sensor shows when it finds metal. This makes setting it up and fixing problems faster. - IP67 waterproof rating - The waterproof inductive proximity sensor, including M12 and other sizes, is sealed against dust and liquids. It's good for machine tool environments. Applications - Checking if metal parts are in the right spot in a jig or fixture - Counting gear teeth to measure speed - Working as end-stop or homing switches on automated equipment What It Is This is a 3-wire magnetic sensor, specifically an M12 NPN NO proximity sensor, designed for detecting objects without physical contact. It operates within a DC voltage range of 6-36V and has a detection distance of 2mm. As an inductive sensor, it creates an electromagnetic field to sense metallic objects. It is a type of industrial sensor, often referred to as a barrel sensor due to its M12 housing diameter. This electronics module provides a non-contact sensing solution for various applications. Key Uses & Applications Proximity sensors like this M12 NPN NO model are widely used in automated systems for object detection and positioning. Common applications include: - Machine automation: Detecting the presence of parts on a conveyor belt. - Robotics: Ensuring proper component placement or collision avoidance. - Industrial control: Monitoring the position of machine elements. - Security systems: Sensing door or gate closure without physical switches. The 2mm detection distance makes it suitable for precise sensing tasks where objects are in close proximity. How to Choose When selecting a proximity sensor, consider the material of the object to be detected; this inductive sensor is for metallic targets. The operating voltage of DC 6-36V needs to match your system. Evaluate the required detection distance; this model offers 2mm, but other options like 1mm, 4mm, 5mm, 8mm, or 10mm are available. The M12 housing diameter is a common size, but M8, M18, and M30 are also options. The NPN output type and NO (normally open) output state dictate how the sensor integrates with your control system. To test a proximity sensor, apply power and use a metal object to check for an output signal change.
