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.

Q: What are the specific detection distances for each size from M8 to M30? A: The sensing distance increases with the sensor's diameter. The M8 is 1-2mm, the M12 is 2-4mm, the M18 is 5-8mm, and the largest M30 model detects metal from 8-10mm away.. Q: How does the sensor hold up in a typical machine shop environment? A: It's built for those conditions with a threaded metal body for secure mounting and an IP67 rating. This means it's sealed against coolant, oil, and dust, making it suitable for machine tool applications.. Q: Can I get this switch with different electrical outputs? A: Absolutely. We stock these in NPN and PNP configurations to match your control system. You can also choose between Normally Open (NO) or Normally Closed (NC) logic for each type.. Q: What kind of warranty comes with this proximity switch? A: It comes with a standard 12-month warranty that protects against any manufacturing faults. If the switch fails within a year due to a defect, we will provide a replacement.. Q: I need to detect only metal parts on my line. Is this the right type of magnetic sensor for that task? A: This is an inductive proximity sensor, which is different from a magnetic sensor that detects magnets. It works by creating a field that senses metal, so it's exactly what you need for detecting ferrous and non-ferrous metal parts while ignoring other materials..
