This inductive proximity sensor finds metal objects without touching them. It's an industrial switch for automation, made in various sizes and sensing distances. This unit is for metal parts only, unlike a capacitive sensor. Features and Benefits
- Different connection options (PNP/NPN, NO/NC) - This lets you hook it up to different PLCs and control systems. NPN draws current to ground, while PNP sends current from V+, giving you wiring choices.
- IP67-rated housing - It keeps out dust and can go underwater up to 1 meter. This means it works well in dirty or wet factory areas.
- Built-in LED light - You can see right away when the sensor finds an object. This makes setting it up and testing much quicker.
- Works with 6-36V DC - This 3-wire DC sensor works with common 12V and 24V DC industrial power systems. Applications
- Counting metal parts on a factory conveyor belt.
- Checking a component's position in an automated assembly machine.
- Finding tools in a CNC machine's tool holder.
What It Is
This capacitive sensor is an industrial sensor designed for automation tasks. It features an M18 diameter and a PNP Normally Open (NO) output configuration. Proximity sensors, like this one, detect the presence or absence of objects without physical contact. This particular model offers a 5mm detection distance. While this specific product is capacitive, proximity sensors can also operate on an inductive principle, as seen in other models within the category.
Key Uses & Applications
Capacitive sensors are widely used in various automation applications where reliable object detection is crucial. Their ability to detect a range of materials makes them versatile. Common applications include material handling, level sensing for liquids or granular materials, and position sensing for machinery components. The 5mm detection distance of this M18 PNP NO sensor makes it suitable for precise, short-range detection tasks in industrial settings.
How to Choose
When selecting a proximity sensor, consider the detection distance required; options range from 1.5mm to 15mm. The output state (Normally Open or Normally Closed) and output type (PNP or NPN) are also critical for compatibility with your control system. Sensor diameter, available in 8mm, 12mm, 18mm, and 30mm, determines mounting options. To test a proximity sensor, apply power and observe the output change when an object is presented within its detection range.
Weight: Varies by model. Detection Distance: 1.5mm, 2mm, 4mm, 5mm, 8mm, 10mm, 15mm. Detection Principle: Inductive. Output State: NO (Normally Open), NC (Normally Closed). Output Type: PNP, NPN. Sensor Diameter: 8mm, 12mm, 18mm, 30mm. Housing Material: Nickel-plated brass or plastic (varies by model). Operating Voltage: 10-30V DC (typical). Output State: Normally Open (NO), Normally Closed (NC). Output Type: PNP, NPN. Protection Rating: IP67 (typical). Brand: OMCH Autonics Type. Detection Distance (PR08): 1.5mm / 2mm. Detection Distance (PR12): 2mm / 4mm. Detection Distance (PR18): 5mm / 8mm. Detection Distance (PR30): 10mm / 15mm. Model Series: PR08, PR12, PR18, PR30. Product Type: Inductive Proximity Switch Sensor. Sensing Principle: Inductive (detects metallic objects). Switching Frequency: Up to 1kHz (typical). Q: What are the sensing distances for the 12mm and 18mm models? A: The PR12 model offers a 2mm range for the shielded version and 4mm for the unshielded one. For the larger PR18 sensor, the shielded type detects up to 5mm, while the unshielded type reaches 8mm.. Q: What is the sensor body made of? Will it hold up around machine coolants? A: The housing is nickel-plated brass, which resists corrosion well. These sensors also have an IP67 rating, so they are fully sealed against dust and can handle being temporarily submerged in liquids.. Q: I need a normally open sensor for my PLC. Can I get this in both PNP and NPN? A: Yes, you can select the exact configuration you need. We offer them with PNP or NPN outputs, and you can also choose between normally open (NO) or normally closed (NC) logic for either type.. Q: I'm detecting aluminum parts on a conveyor. Is this inductive sensor a better choice than a capacitive sensor? A: For detecting metal like aluminum, this inductive sensor is ideal because it only reacts to metallic objects. A capacitive sensor can also detect non-metals, which might lead to false triggers from other items in the area.. Q: My machinery is in a warehouse that gets pretty cold. What's the operating temperature for these? A: These sensors are designed to work reliably in a wide temperature range, from -25°C all the way up to 70°C. That covers most industrial environments, including unheated spaces during winter..
