Photointerrupters, such as OPB481P11Z, are popular optical sensors used to detect objects passing through them. It consists of an infrared LED and an integrated phototransistor. The OPB481P11Z is a slot-type photointerrupter with a logic output.

The OPB481P11Z photointerrupter operates on the principle of a light-based transmission of information. The infrared LED emits light which is picked up by the integrated phototransistor. When an object passes through the slot, it blocks the light from the LED, causing the phototransistor to switch off. This change in the phototransistor’s state is detected as a logic output.

The OPB481P11Z has a wide range of applications including object counting, edge detection, position tracking, presence sensing, and motion sensing. It can be used in industrial, automotive, consumer, and medical applications. It is designed to work in harsh environments and to withstand high speeds.

For industrial applications, the OPB481P11Z can be used for the detection of objects passing through conveyor belts or for counting parts. In automotive applications, it can be used for brake or gear shift position detection, and as a collision detection or safety feature.

In consumer applications, the OPB481P11Z can be used in automated doors and lift systems. In medical applications, it can be used for patient monitoring or for reading bar codes.

The OPB481P11Z photointerrupter is a reliable and accurate optical sensing device with a wide range of applications in many industries. It is a low-cost and easy-to-install solution and its logic output ensures accurate and reliable results. With its robust design, it is well suited for use in harsh environments and for high-speed applications.
