Detailed Pin Configuration

The OPB625 typically features a standard 4-pin configuration: 1. VCC (Power Supply) 2. GND (Ground) 3. Output 4. N/C (No Connection)

Functional Features

The OPB625 operates by emitting infrared light from its LED and detecting the reflected light using its phototransistor. When an object is present within its sensing distance, the phototransistor output transitions from a high to a low state, indicating the presence of the object.

Advantages and Disadvantages

Advantages

  • High sensitivity
  • Compact size
  • Reliable performance
  • Wide operating temperature range

Disadvantages

  • Limited sensing distance
  • Susceptible to ambient light interference

Working Principles

The working principle of the OPB625 is based on the modulation of infrared light. When an object is placed within its detection range, the amount of reflected light changes, causing the phototransistor to switch its output state.

Detailed Application Field Plans

The OPB625 finds extensive application in various fields such as: - Industrial automation for object detection - Robotics for proximity sensing - Printers and copiers for paper jam detection - Vending machines for product dispensing control

Detailed and Complete Alternative Models

Some alternative models to the OPB625 include: - TCRT5000: Similar infrared reflective sensor with a longer sensing distance - QRE1113: Reflective object sensor with analog output for distance measurement - GP2Y0A21YK0F: Infrared proximity sensor with a compact form factor

In conclusion, the OPB625 serves as a reliable and compact optical sensor with applications across diverse industries, despite its limitations in sensing distance and susceptibility to ambient light interference.
