HOA1883-501 Encyclopedia Entry

Product Overview

The HOA1883-501 is a component belonging to the category of optical sensors. It is commonly used for detecting the presence or absence of an object, and it possesses characteristics such as high sensitivity, compact packaging, and reliable performance. The package includes the sensor itself along with any necessary accompanying components, and its essence lies in its ability to accurately detect objects within its range. The packaging typically consists of individual units, and the quantity may vary based on the manufacturer's specifications.

Specifications

• Operating Voltage: 5V
• Output Type: Digital
• Sensing Distance: 3mm
• Operating Temperature: -40°C to 85°C
• Package Type: Through Hole

Detailed Pin Configuration

The HOA1883-501 features a standard pin configuration with three pins: 1. VCC (Voltage Input) 2. GND (Ground) 3. OUT (Digital Output)

Functional Features

The sensor utilizes an infrared light source and a phototransistor to detect the presence of an object within its sensing distance. When an object is present, the infrared light is reflected back to the phototransistor, causing the digital output to switch to a logical high state. Conversely, when no object is detected, the output remains at a logical low state.

Advantages and Disadvantages

Advantages

• High sensitivity for accurate object detection
• Compact design for easy integration into various applications
• Reliable performance across a wide temperature range

Disadvantages

• Limited sensing distance of 3mm
• Susceptible to ambient light interference in certain environments

Working Principles

The HOA1883-501 operates based on the principle of reflection of infrared light. When an object is within its sensing range, the infrared light emitted by the sensor reflects off the object and is received by the phototransistor, resulting in a change in the digital output state.

Detailed Application Field Plans

The HOA1883-501 is widely used in applications such as: - Object detection in automated machinery - Paper detection in printers and copiers - Proximity sensing in consumer electronics

Detailed and Complete Alternative Models

For those seeking alternative models, the following options are available: - HOA1870 Series - HOA1906 Series - HOA0901 Series

In conclusion, the HOA1883-501 optical sensor offers high sensitivity and reliable performance, making it suitable for a variety of object detection applications. While it has limitations in sensing distance and susceptibility to ambient light interference, its compact design and accurate detection capabilities make it a valuable component in many electronic systems.
