Optical sensors have been used for decades in industry to detect the presence of objects or measure changes in light. Today, optical sensors are also used in consumer products such as mobile phones and automobiles. Photointerrupters, one type of optical sensor, are used to detect the interruption of a light beam caused by the movement of an object; these devices are typically used for motion sensing and presence control. The OPB877T55 is an example of a photointerrupter, specifically a slot type with a transistor output. This article will explain the applicationfield and working principle of the OPB877T55.
The OPB877T55 consists of two components: a transmitter, which emits a light beam, and a receiver, which detects the interruption of the light beam. The transmitter is an infrared light-emitting diode (LED) and the receiver is a phototransistor. The two components are packaged within a single unit. The dimensions of the unit are 0.45" x 0.182" x 0.112" and its mounting style is through-hole.
The OPB877T55 is designed to detect the interruption of the infrared light beam by an object moving between transmitter and receiver. The device is suitable for use in applications where the object may move in any direction and at any speed. The device is sensitive to changes in the amount of light, so it can be used to detect objects that are moving slowly or stationary.
The working principle of the OPB877T55 is relatively simple. The transmitter emits a continuous infrared light beam that is directed towards the receiver. If an object is placed between the transmitter and receiver, the light beam is interrupted and the receiver does not detect the light. This triggers a change in the output of the receiver, which can be detected by a controlling circuit.
The OPB877T55 is suitable for a wide range of applications. It can be used for presence detection, motion sensing, and level detection. It is also suitable for use in consumer and industrial products such as mobile phones, robotics, gaming machines, elevators, vending machines, remote controllers, and automated assembly lines.
The OPB877T55 can operate in any environment, including high temperatures and wet conditions. The device has a wide operating temperature range (-25°C to +105°C) and is resistant to both wear and corrosion. It is also RoHS compliant and UL recognized.
In conclusion, the OPB877T55 is an example of a photointerrupter, specifically a slot type with a transistor output. It is suitable for a wide range of applications, including presence detection, motion sensing, and level detection. The device is robust and has a wide operating temperature range, making it suitable for use in both consumer and industrial products.
