OPB829CZ Encyclopedia Entry

Product Overview

The OPB829CZ is a photo interrupter sensor belonging to the category of optoelectronic devices. It is commonly used for detecting the presence or absence of an object, and it is characterized by its compact size, high sensitivity, and reliable performance. The sensor is typically packaged in a plastic housing and is available in various quantities per package.

Specifications

• Operating Wavelength: 950 nm
• Aperture Width: 0.030" (0.76 mm)
• Aperture Height: 0.120" (3.05 mm)
• Output Configuration: Phototransistor
• Supply Voltage: 5 V
• Operating Temperature Range: -40°C to 85°C

Detailed Pin Configuration

The OPB829CZ sensor has a standard 4-pin configuration: 1. VCC (Supply Voltage) 2. GND (Ground) 3. Output 4. N/C (Not Connected)

Functional Features

The OPB829CZ operates based on the interruption of the infrared light beam between the emitter and detector. When an object obstructs the light path, the output of the sensor changes, indicating the presence of the object. This functionality makes it suitable for applications requiring precise object detection.

Advantages and Disadvantages

Advantages

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

Disadvantages

• Limited operating voltage range
• Susceptible to ambient light interference

Working Principles

The working principle of the OPB829CZ is based on the modulation of the infrared light emitted by the internal LED. When the emitted light is interrupted by an object, the phototransistor detects the change in light intensity and produces a corresponding output signal.

Detailed Application Field Plans

The OPB829CZ sensor finds extensive application in various fields, including: - Object detection in industrial automation - Paper and label detection in printing and packaging machinery - Position sensing in robotics and motion control systems - Proximity sensing in consumer electronics and appliances

Detailed and Complete Alternative Models

Some alternative models to the OPB829CZ sensor include: - OPB820WZ: Similar photo interrupter with wider aperture - OPB830WZ: Photo interrupter with enhanced ambient light rejection - OPB840WZ: High-speed photo interrupter for rapid object detection

In conclusion, the OPB829CZ photo interrupter sensor offers a compact and reliable solution for object detection applications across various industries, despite its limitations in operating voltage range and susceptibility to ambient light interference.
