H22A2 Optical Sensor

Product Overview

The H22A2 optical sensor belongs to the category of reflective object sensors and is commonly used for detecting the presence or absence of objects. Its characteristics include high sensitivity, compact size, and reliable performance. The sensor is typically packaged in a durable housing with an integrated infrared LED and phototransistor. It is available in various packaging/quantity options to suit different application requirements.

Specifications

  • Operating Voltage: 5V
  • Current Consumption: 20mA
  • Sensing Distance: 3mm to 10mm
  • Response Time: 1ms
  • Output: Digital (High/Low)

Detailed Pin Configuration

The H22A2 sensor typically features three pins: 1. VCC (5V) 2. GND (Ground) 3. OUT (Digital Output)

Functional Features

The H22A2 sensor operates based on the principle of reflection detection. When an object is within the sensing distance, the infrared light emitted by the integrated LED is reflected back to the phototransistor, causing a change in its output state. This functionality allows for accurate object detection in various applications.

Advantages and Disadvantages

Advantages

  • High sensitivity
  • Compact size
  • Fast response time
  • Reliable performance

Disadvantages

  • Limited sensing distance
  • Susceptible to ambient light interference

Working Principles

The H22A2 sensor works by emitting infrared light and detecting its reflection from nearby objects. When the reflected light is detected, the sensor's output changes, indicating the presence of an object.

Detailed Application Field Plans

The H22A2 sensor finds extensive use in automated systems for object detection, such as in industrial machinery, robotics, and assembly lines. It is also employed in consumer electronics for proximity sensing and object detection applications.

Detailed and Complete Alternative Models

Some alternative models to the H22A2 sensor include: - TCRT5000: A similar reflective optical sensor with adjustable potentiometer for sensitivity control. - GP2Y0A21YK0F: Infrared distance measuring sensor with analog output for precise distance measurement.

In conclusion, the H22A2 optical sensor offers high sensitivity and reliable performance, making it suitable for a wide range of object detection applications across various industries.
