M30 Photoelectric Sensor (Through Beam)

 

M30 Photoelectric Sensor (Through Beam)

The M30 photoelectric sensor is a versatile and widely used type of industrial sensor with a 30mm diameter, designed for reliable object detection in various automation and control applications. Below is a comprehensive overview of its key features, types, and common applications:

Features:

  1. Design and Construction:

    • Size: 30mm diameter cylindrical body, which is a standard in industrial environments.
    • Material: Often made of robust materials like stainless steel or reinforced plastic to withstand harsh conditions.
  2. Detection Methods:

    • Diffuse Mode: The sensor emits light and detects the reflection from the object itself.
    • Retro-reflective Mode: The sensor uses a reflector to detect objects when the light path is interrupted.
    • Through-beam Mode: Consists of a separate emitter and receiver. Detection occurs when an object breaks the light beam between them.
  3. Sensing Range:

    • Varies depending on the mode and specific model, typically ranging from a few centimeters to several meters.
  4. Output Types:

    • Digital Outputs: PNP (sourcing) or NPN (sinking) transistor outputs for interfacing with control systems.
    • Analog Outputs: For continuous measurement applications.
  5. Environmental Protection:

    • High IP ratings (e.g., IP67 or IP69K) for protection against dust, water, and other environmental factors.
  6. Connection Options:

    • Various connectors, including M12 connectors, cable glands, and pre-wired cable options.
  7. Adjustability:

    • Sensitivity and range adjustments via potentiometers or teach-in buttons.

Applications:

  1. Manufacturing and Automation:

    • Detecting presence or absence of parts on conveyor belts, counting items, and ensuring correct positioning.
  2. Packaging Industry:

    • Verifying the presence of products in packages, checking package integrity, and detecting packaging materials.
  3. Material Handling:

    • Object detection in automated guided vehicles (AGVs) and robotic arms.
  4. Quality Control:

    • Ensuring components are present, correctly placed, and detecting defects in assembly lines.
  5. Safety Systems:

    • Implementing through-beam sensors as part of safety light curtains to protect operators.
