M30 Photoelectric Sensor (Diffuse Reflective)
M30 Photoelectric Sensor (Diffuse Reflective)
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:
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.
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.
Sensing Range:
- Varies depending on the mode and specific model, typically ranging from a few centimeters to several meters.
Output Types:
- Digital Outputs: PNP (sourcing) or NPN (sinking) transistor outputs for interfacing with control systems.
- Analog Outputs: For continuous measurement applications.
Environmental Protection:
- High IP ratings (e.g., IP67 or IP69K) for protection against dust, water, and other environmental factors.
Connection Options:
- Various connectors, including M12 connectors, cable glands, and pre-wired cable options.
Adjustability:
- Sensitivity and range adjustments via potentiometers or teach-in buttons.
Applications:
Manufacturing and Automation:
- Detecting presence or absence of parts on conveyor belts, counting items, and ensuring correct positioning.
Packaging Industry:
- Verifying the presence of products in packages, checking package integrity, and detecting packaging materials.
Material Handling:
- Object detection in automated guided vehicles (AGVs) and robotic arms.
Quality Control:
- Ensuring components are present, correctly placed, and detecting defects in assembly lines.
Safety Systems:
- Implementing through-beam sensors as part of safety light curtains to protect operators.
