The H22A2 optical sensors from Isocom Components 2004 LTD are designed for use in the measuring and detection of light. These slot type photointerrupters feature transistor output and PC pins. When placed in an opening or gap and exposed to light, the photointerrupter reacts to the light and is able to measure and detect the amount of light received and calculate the distance or level of light. The signal produced is reliable and consistent, allowing for accurate and reliable data collection. The H22A2 optical sensors are rugged and resistant to impacts, allowing them to be used in harsh and extreme conditions. The sensors are simple to install and use, making them an ideal choice for any light detection application.
