OPB890T55Z

Optical Sensors comprise a set of transducers which are used to detect a certain type of radiation, such as light. One of the most common types of optical sensors is the Photointerrupter, which works by breaking an infrared beam and then measuring the interruption period. Slot type Photointerrupters, such as the OPB890T55Z, are specially designed to detect objects that enter or leave slots or gates of various shapes and thickness.

The OPB890T55Z is a slot type Photointerrupter, featuring a transistor output, which can be used to detect objects that have entered or exited a slot of up to 4mm in width and 16mm in length. It can detect objects that move at speeds ranging from 1 cm/s to 300 cm/s, with a sensitivity of 0.1 to 1.2 mA/W/sr. The sensor comprises a miniature emitter and detector housed in a package with a predetermined size, and is constructed from high impact polystyrene for improved durability and performance.

The device works by emitting a beam of infrared light along a predetermined path. When an object passes through the slot, it will partially or completely block the signal, which then triggers a transistor switch to activate. This signal can then be used as a control input for any number of applications. Some of the common uses for the OPB890T55Z include door open/close monitoring, object detection, and inventory control systems.

Overall, the OPB890T55Z is an excellent example of a slot type Photointerrupter with transistor output that can be used in a variety of applications. Its miniature size makes it ideal for tight spaces, while the high-sensitivity and durable construction make it suitable for a wide range of environments. As such, the OPB890T55Z is an excellent choice for anyone looking for an optical sensor with transistor output that can detect the movement of objects.
