Optical sensors are an important class of detectors that are used in a broad range of applications, from medical to industrial. They use light energy to detect and measure physical and chemical phenomena, and they often provide a more reliable and accurate performance than their electronic counterparts. Photointerrupters are one type of optical sensor that can be used to measure the presence or absence of an object, and to count how many objects have passed through a given area.

The OPB875T55 is a slot type photointerrupter with a transistor output. It is available in both through-hole and surface-mount packages, making it suitable for a wide range of applications. The device is designed for use in systems that need to detect the presence or absence of a target object, such as an security gate or industrial safety sensors. The OPB875T55 has a compact design that requires minimal space on a circuit board, making it easy to integrate into existing systems.

The working principle of the OPB875T55 is based on the use of an emitter and a detector on opposite sides of the slot. When no target object is present, the two emitters and detectors are aligned and the circuit is in an OFF state. When the target object passes through the slot, it interrupts the alignment of the two emitters and detectors and the circuit changes to an ON state. This change in state is detected by the external circuit, which can then be used to trigger an alarm or to control other systems.

The OPB875T55 is a reliable and cost-effective optical sensor that can be used in a wide range of applications. It is designed to detect the presence or absence of a target object, and can be used to trigger alarms or control other systems. The device has a compact design and is available in through-hole and surface-mount packages, making it easy to integrate into existing systems.
