φ21mm Ring Inductive proximity Sensor(plug-in)

A φ21mm ring inductive proximity sensor is an electronic device designed to detect the presence of metallic objects within its sensing range. The "φ21mm" specification indicates that the sensor has a 21 millimeter diameter hole or ring, allowing objects to pass through the sensor's detection area. This type of sensor is particularly useful in applications where it is necessary to monitor or count metal objects moving through a specific point.

Key Features

  1. Sensing Principle: Inductive, utilizing electromagnetic fields to detect metal objects.
  2. Diameter: 21mm (φ21mm), indicating the diameter of the ring through which objects pass.
  3. Detection Range: Typically small and highly dependent on the size, shape, and material of the target object.
  4. Housing Material: Usually made from durable materials such as stainless steel or industrial-grade plastic to withstand harsh environments.
  5. Output Type: Common types include NPN, PNP, Normally Open (NO), and Normally Closed (NC).
  6. Power Supply: Usually operates on 10-30V DC, though specific models may vary.

    Applications

    • Manufacturing: Monitoring and counting metal parts as they move through production lines.
    • Automation Systems: Detecting the presence and position of metal objects in automated machinery.
    • Quality Control: Ensuring that all parts in a process are metal or detecting metal contaminants.
    • Robotics: Position sensing and part detection in robotic assembly lines.
