The OPB493T11Z Slot Type Logic Output Photointerrupter is a low-profile, small-sized device that is designed to detect movement, light, darkness, and other objects in its beam’s path. It consists of a transmitter and receiver inside the same housing, which when an object interrupts the beam, the output status will change accordingly. Photointerrupters within this category provide a 2-pin logic output, with the ON/OFF status indicated by either a low or high signal, respectively. This device is ideal for detecting various objects in a wide range of applications, such as packaging machines, elevators, doors, automatic gates, and more. Additionally, the device has a wide angle detection range of 40°.

The OPB493T11Z Photointerrupter utilizes two LEDs located inside the same housing with the output unit normally “ON” (NPN transistor). When an object interrupts the emitted infrared light between the emitter and receiver, the output will switch status to “OFF” (PNP transistor) resulting in a signal of low being sent to the control signal. This device also features extremely fast response times, with a maximum operating speed of up to 100m/s, allowing its use in applications requiring high speed and accuracy. Furthermore, the device possesses a wide operating temperature range of -25°C to +85°C, making it suitable for using in a variety of climates.

Moreover, the OPB493T11Z has a wide operating voltage range of 3.5 to 24VDC, meaning it can be used with a wide variety of DC power sources. Additionally, it is equipped with an efficient reverse protection diode, which can provide a stable, uninterrupted performance even in the event of a sudden reverse voltage surge. Its small size (20mm x 6mm) further allows it to fit into tight, confined spaces. In terms of its light immunity, the device can withstand up to 10000 lux of direct sunlight, making it suitable for outdoor applications as well.

In terms of its general application usage, the OPB493T11Z is usually used to detect the presence of an object, understand changes in movement, or determine the darkness/brightness levels of its environment. Some of its more common uses include its integration in automatic door openers, vending/ticket machines, printing equipment, optical sorting systems, and other indoor automation. Its small size and wide operating voltage range also make it a good choice for use in industrialized areas and other harsh environments.

In conclusion, the OPB493T11Z Photointerrupter is a versatile low-profile device capable of transferring a simple “ON/OFF” signal to a variety of control systems. It has a large operating voltage range, wide angle detection of 40°, and extremely fast response times to enable its use in a wide range of applications. It is capable of withstanding up to 10000 lux of direct sunlight, as well as an operating temperature range of -25°C to +85°C. Overall, the OPB493T11Z is a reliable and efficient way to detect the presence of objects, light levels, and other environmental indicators.
