What is a built-in type Photomicrosensors (photointerrupter)?

ID: FAQE40001E



A built-in type Photomicrosensors, also known as a photointerrupter, is a basic Optical Sensor used to detect object presence in consumer equipment (e.g. multifunction printers, IP cameras, robotic cleaners) and commercial devices (e.g. ATMs, packaging machines, copy machines).
In addition to the component level Photomicrosensors, Omron offers Photomicrosensors for industrial applications, primarily for factory facility equipment and factory automation (FA).


The difference between Component Level Photomicrosensors and Industrial Photomicrosensors is shown in the table below. Please note that these points do not necessarily apply to all the available Photomicrosensors models. Please check the specification datasheet for details on power supply voltage to determine the switching capacity condition and other requirements when choosing a model.

Quick tips

The following illustration is a general example of the connecting method of different built-in type Photomicrosensors. PCB mounting is the most popular method of sensor attachment. Surface mount (SMD) is effective for downsizing and allows fewer man-hours of assembly. Pre-wired, or connector style is convenient for wiring and maintenance, and is ideal for detecting an object placed far from the main PCB. We advise users to choose a sensor that best matches the mechanical structure of the target device/equipment.
