OPB920CZ Encyclopedia Entry

Product Overview

The OPB920CZ is a reflective object sensor that belongs to the category of optoelectronic devices. It is commonly used for detecting the presence or absence of objects, and it possesses unique characteristics that make it suitable for various applications. The sensor is typically packaged in a compact housing and is available in different packaging quantities to suit specific requirements.

Specifications

• Operating Voltage: 4.5V to 16V
• Output Type: Phototransistor
• Sensing Distance: Up to 0.125 inches (3.18mm)
• Operating Temperature Range: -40°C to 85°C
• Package Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)

Detailed Pin Configuration

The OPB920CZ sensor has a standard 4-pin configuration: 1. VCC (Power Supply) 2. GND (Ground) 3. Output 4. N/C (Not Connected)

Functional Features

The sensor utilizes a phototransistor to detect the presence of an object by reflecting light off its surface. When an object is within the sensing distance, the output of the sensor switches to indicate the detection.

Advantages and Disadvantages

Advantages

• Compact size
• Wide operating voltage range
• Reliable object detection
• Suitable for harsh environments

Disadvantages

• Limited sensing distance
• Susceptible to ambient light interference

Working Principles

The OPB920CZ operates based on the principle of reflection. When the emitted light from the sensor reflects off an object and returns to the phototransistor, it triggers a change in the output state, indicating the presence of the object.

Detailed Application Field Plans

The OPB920CZ sensor finds extensive use in various applications, including but not limited to: - Industrial automation for object detection in assembly lines - Robotics for proximity sensing and obstacle detection - Security systems for intrusion detection - Printers and copiers for paper jam detection

Detailed and Complete Alternative Models

• TCRT5000: A similar reflective object sensor with comparable specifications
