The OPB840W55 is an optical sensor specifically designed for applications that require a transistor output to provide accurate and reliable results. It is an especially useful device for applications where high speed, high resolution, or very low power consumption are at a premium. The OPB840W55 is capable of operating in a wide range of temperature conditions and can be used in any number of applications such as industrial automation, medical imaging, lighting, gaming, chemical process control, and more.

The OPB840W55 is part of the photointerrupter slot type family and utilizes a solid state device consisting of a small, monolithic package containing an infrared-emitting diode (IRED), a phototransistor, and an IC (integrated circuit). This type of device can detect the presence or absence of a moving object when light is interrupted or emitted. The OPB840W55 features two types of transistor outputs, an NPN type and a PNP type, which makes it versatile for different types of applications.

The OPB840W55 works by emitting an infrared light from the IRED. This light is picked up by the phototransistor, which in turn triggers the integrated circuit (IC). This IC processes the digital signals and sends them to the output, which is available in either an NPN type or PNP type transistor. The output can then be used to trigger external electronic devices, such as relays, alarms, motors, and more.

The OPB840W55 also features a built-in automatic reset system, which helps to minimize false triggering caused by light spill or electrical noise. This prevents wasted energy and increases system reliability. Additionally, the OPB840W55 is designed with a wide operating voltage range from 5V to 24V, making it suitable for many different types of applications.

The OPB840W55 is highly accurate and reliable, making it a great choice for applications that require precise digital outputs. Its small size, wide operating temperature range, and low power consumption make it a great choice for any application where accuracy, reliability, and low energy consumption are the top priorities.
