OPB827B

Product Overview

The OPB827B belongs to the category of optical sensors and is commonly used for detecting the presence or absence of an object. Its characteristics include high sensitivity, compact size, and reliable performance. The package typically includes the sensor itself along with any necessary mounting hardware. The essence of the OPB827B lies in its ability to accurately detect objects within its range. It is usually available in standard packaging with varying quantities depending on the supplier.

Specifications

• Operating Voltage: 4.5V to 5.5V
• Output Type: Phototransistor
• Sensing Method: Reflective
• Operating Temperature: -40°C to 85°C
• Response Time: 14µs

Detailed Pin Configuration

The OPB827B typically consists of three pins: 1. VCC (Power supply) 2. GND (Ground) 3. OUT (Output)

Functional Features

The OPB827B operates by emitting a beam of light and detecting its reflection off an object. When the light beam is interrupted by the presence of an object, the phototransistor output is activated, signaling the detection of the object.

Advantages and Disadvantages

Advantages

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

Disadvantages

• Limited range
• Susceptible to ambient light interference

Working Principles

The working principle of the OPB827B is based on the reflection of light. When an object is present within the sensor's range, it obstructs the emitted light, causing a change in the phototransistor's conductivity and resulting in the activation of the output signal.

Detailed Application Field Plans

The OPB827B 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 OPB827B include: - TCRT5000: A similar reflective optical sensor with comparable specifications - QRE1113: Another reflective sensor suitable for object detection applications

In conclusion, the OPB827B serves as a reliable and compact optical sensor with high sensitivity, making it suitable for a wide range of object detection applications across different industries.
