OPB695A

Optical sensors are devices used to convert different forms of energy into electrical signals. Among the most common sensors in this category are photointerrupters. These sensors are capable of detecting the objects in front of them and of providing a logic output. OPB695A is a type of photointerrupter, specially designed for slot type applications.

The OPB695A is operated by a simple principle. The device consists of an infrared LED transmitter and an NPN Silicon phototransistor receiver. The infrared LED is positioned in such a way that it emits an infrared beam through a narrow clearance in the front of the device. The NPN Silicon phototransistor receiver is placed close to the LED, receiving the infrared beam as it passes through the slot. When an object passes through the slot, the receivers detects the interruption of the infrared beam and an output logic voltage is generated.

The OPB695A provides many advantages over other photointerrupter types. The most noteworthy of these is its extremely fast response time of 1 microsecond, making it ideal for precise and rapid applications. Additionally, the device is designed for low-cost easy integration into existing systems, potentially reducing the need for extensive development work. OPB695A is also known for its reliability and durability due to its high quality construction and material selection.

The main application field of the OPB695A is in slot type devices, such as pick and place devices used in automated production lines. The device can be attached to the side of a conveyor belt, allowing it to detect objects moving on the belt. The device is capable of providing extremely precise output logic signals, enabling it to detect and differentiate between objects of various sizes. Additionally, the OPB695A is used in a variety of other applications such as presence sensing, material sorting, and safety protection devices.

In summary, the OPB695A is a fast, reliable, and cost-effective device that is specially designed for slot type applications. The device consists of an LED transmitter and Silicon phototransistor receiver, with a response time of 1 microsecond. It is mainly used in pick and place devices, as well as in presence sensing, material sorting, and safety protection devices.
