OPB870P51TXV Datasheet/PDFOptical Sensors - Photointerrupters - Slot Type - Transistor Output
The OPB870P51TXV belongs to a category of slot type photointerrupters, which detect changes in the amount of light on a specific medium such as glass or plastic. It uses a transistor output, which allows it to be control devices for an automated system. This article looks at the working principle and application fields of the OPB870P51TXV.
Working Principle of a Slot Type Photointerrupter
The working principle of slot type photointerrupters is based on a transistor output which detects when a moving object passes between the slot. The light is usually supplied by an LED (Light Emitting Diode) at the top of the slot, and when the object passes through the slot, the amount of light detected is decreased by the transistor output. This decrease in light signals the detector, which can then be used to control the automated system.
In the case of the OPB870P51TXV, the amount of light is detected using the IR transmission range (850-950nm). This allows it to detect even small objects, with a detection range of up to 20mm. The device also has a wide operating temperature range and a low power consumption, making it suitable for a variety of applications.
Application Fields of the OPB870P51TXV
The OPB870P51TXV has a variety of application fields due to its wide operating temperature range and low power consumption. One of the applications for this device is in medical equipment, where it is used to detect when a patient needs to be monitored. It can also be used in machinery, to detect when a part needs to be replaced, or when an automated system needs to be turned off or on. It can also be used in security systems, to detect the presence of an intruder.
In addition, the OPB870P51TXV can be used in industrial and domestic applications. For instance, it can be used in washers, dryers, refrigerators, ovens, and other appliances to detect when a particular cycle has been completed. It can also be used in HVAC (Heating, Ventilation, and Air Conditioning) systems, to detect when the temperature or humidity has changed. The OPB870P51TXV can also be used in robotics, to detect when an object has moved.
Conclusion
The OPB870P51TXV is a slot type photointerrupter with a transistor output, which is used to detect changes in the amount of light on a specific medium. It has a wide operating temperature range and a low power consumption, making it suitable for use in a variety of applications, such as medical equipment, machinery, security systems, and robotics. It can also be used in industrial and domestic applications.
