Isocom Components 2004 LTD H22A1 Environmental and export classification status description

The Fairchild Semiconductor H22A1 is a compact, cost-effective transmissive optical sensor device that consists of a gallium arsenide infrared LED emitter and a phototransistor detector in a single package. It is commonly used for proximity sensing and object detection applications. Functions: 1. Detects the presence or absence of an object by sensing the interruption of light between the emitter and detector. 2. Converts the detected light signal into an electrical output. Applications: 1. Object detection in automated industrial processes. 2. Proximity sensing in consumer electronics like printers and copiers. 3. Coin detection in vending machines. 4. Encoders in robotics and automation. Alternative Components: 1. Vishay CNY70 Optical Sensor 2. Sharp GP1A57HRJ00F Optical Sensor 3. Broadcom APDS-9008 Digital Ambient Light Sensor Embedded Modules: 1. Arduino Uno with H22A1 Sensor Shield 2. Raspberry Pi with H22A1 GPIO connections Q&A Related to Fairchild Semiconductor H22A1: 1. Q: How does the Fairchild Semiconductor H22A1 detect objects? A: The H22A1 uses the infrared LED emitter to send a beam of light, which is then detected by the phototransistor. When an object obstructs the light path between the emitter and detector, the sensor registers a change in light intensity. 2. Q: What is the operating voltage range for the Fairchild Semiconductor H22A1? A: The H22A1 typically operates within a voltage range of 4.5V to 5.5V. 3. Q: Can the H22A1 be used for speed sensing applications? A: While the H22A1 is primarily designed for proximity sensing, it can also be used for speed sensing applications by detecting the interruptions in the light beam at different intervals. 4. Q: What are the typical response times of the Fairchild Semiconductor H22A1? A: The H22A1 generally has a fast response time, with typical values ranging from microseconds to milliseconds depending on the application requirements. 5. Q: Is the Fairchild Semiconductor H22A1 suitable for outdoor applications? A: The H22A1 is more suited for indoor applications due to its sensitivity to ambient light interference. Outdoor use may require additional shielding or filtering to ensure reliable performance.
