The OPB872T55 is an optoelectronic device in the slot type transistor output photointerrupter family. This device utilizes infrared light to detect objects passing through a gap. Slot type photointerrupters help to reduce chip size while combining various detector requirements in a single package.

The OPB872T55 is a bi-directional device that is used to detect the presence of an object passing through a gap. It consists of an infrared light emitting diode (LED) and a phototransistor. When there is no object passing through the gap, the phototransistor remains in the off-state. When an object blocks the gap, the LED emits infrared light, which is optically coupled to the phototransistor, turning it on. The transistor output level changes from a low voltage (off-state) to a high voltage (on-state).

The OPB872T55 is designed to operate in a wide range of applications and environments. It can detect the presence of an object without physical contact, making it ideal for equipment protection services, machine automation, rotation speed measurement, timing control, and non-contact sensing.

The OPB872T55 has a wide operating voltage range of 3-24V and can operate for up to 100mA. It has low-power consumption and long-term reliability, with a minimum response time of only 10μs. Its operating temperature ranges from -40°C to +85°C. In addition, the OPB872T55 is compliant with RoHS and REACH standards.

In its basic configuration, the OPB872T55 consists of an infrared LED and an integrated phototransistor. The LED emits infrared light, which is coupled to the integrated phototransistor, turning it on. The transistor output level changes from a low voltage (off-state) to a high voltage (on-state). The phototransistor is designed to detect objects of various shapes and sizes, even when passing through the gap at high speeds.

The OPB872T55 is an ideal device for cost- and space-sensitive applications. Its small package size and low-power consumption make it suitable for a variety of industrial and consumer applications. The device can be used in high-speed sorting machines, object detection systems, machine automation, and more. Its reliable performance and long-term reliability ensure that it is suitable for use in harsh environments.
