Optical sensors have a wide variety of applications in almost every industry, and the OPB871T55TX slot type optical photointerrupter with a transistor output, is no exception. Commonly used for highly accurate position detection, often in automated manufacturing, OPB871T55TX can be used for position sensing, motor speed detection, object detection, and a myriad of other uses.

Slot type photointerrupters such as the OPB871T55TX, make use of an optical transmitter and receiver mounted in a single package. When an object passes between them the light is blocked, and the output signal is changed from logic “low” to logic “high” or vice versa. Flagging objects in motion, slot type photointerrupters are often used in printing presses, conveyors, vending machines, and more.

In terms of working principle, the OPB871T55TX operates by having an LED emitting infrared light towards a phototransistor. The light is reflected off of the object and the signal is amplified and detected as a logic level shift from a low to a high state, equivalent to a ON/OFF switch. When there is a physical object between the LED and the phototransistor, this switch is flipped, and a signal change is registered.

Opb871t55tx is typically used in applications involving the detection of a small object such as a newspaper, envelope, or check. Utilising slot type technology, it is sensitive to small objects and is also able to accurately detect artwork and other objects of thin thickness. With the flexibility to detect objects up to 12mm height, the opb871t55tx is suitable for many applications.

When it comes to power, the opb871t55tx draws 30mA of power very quickly, and has a voltage rating of 7 to 30 volts, depending on the light conditions. It also features an alarm output, a noise rejection filter, and a low current standby input which allows the user to reduce overall power consumption even further. With a response time of less than 10ms, the OPB871T55TX is one of the fastest photointerrupters on the market.

Overall, OPB871T55TX has a wide range of applications and can be used to improve production and increase efficiency. From automated manufacturing lines to sophisticated machinery in medical and lab equipment, the OPB871T55TX optical photointerrupter with transistor output is an important tool in the world of modern technology.
