Product Specifications

Technical details and manufacturing context for Photoelectric Sensor

Definition
A critical component in Grouping Conveyor systems that detects objects on the conveyor line using light emission and reception, enabling precise object counting, positioning, and sorting operations.
Working Principle
Emits a light beam (visible or infrared) from a transmitter; when an object interrupts or reflects this beam, the receiver detects the change in light intensity and converts it into an electrical signal for processing.
Common Materials
Polycarbonate housing, Optical glass lens, LED/Laser diode, Phototransistor/Photodiode
Technical Parameters
  • Sensing distance range typically from 0.1mm to 100m depending on sensor type (mm) Standard Spec
Components / BOM
  • Emitter
    Generates and projects the light beam toward the target area
    Material: LED/Laser diode, optical glass
  • Receiver
    Detects changes in light intensity and converts to electrical signals
    Material: Phototransistor/Photodiode, optical filter
  • Housing Part
    Protects internal components from environmental factors and mechanical damage
    Material: Polycarbonate, stainless steel
  • Lens Part
    Focuses and directs the light beam for optimal sensing performance
    Material: Optical glass, acrylic

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Lens Contamination
Cause: Accumulation of dust, oil, or debris on the sensor lens, blocking or scattering the light beam, often due to inadequate environmental sealing or improper installation in dirty environments.
LED Degradation
Cause: Gradual reduction in light output from the emitter LED over time, typically caused by thermal stress, excessive current, or aging, leading to unreliable detection or complete failure.
Maintenance Indicators
  • Intermittent or erratic detection signals, such as false triggers or missed objects, indicating potential alignment issues, contamination, or component degradation.
  • Visible accumulation of dirt, moisture, or residue on the sensor lens or housing, or audible buzzing/clicking from the sensor during operation, suggesting internal damage or electrical issues.
Engineering Tips
  • Implement regular cleaning schedules using appropriate methods (e.g., lint-free cloths, compressed air) and ensure proper environmental sealing or protective enclosures in dusty, humid, or oily conditions.
  • Use sensors with higher IP ratings for harsh environments, ensure correct alignment and mounting stability, and follow manufacturer guidelines for voltage/current limits to prevent thermal or electrical stress.
