The OPB840W11Z is a Slot Type Transistor Output Photointerrupter device. It is a highly sensitive device which is used for motion detection. It works by allowing the infrared light from the photoemitter to pass through an opaque slot which it then detects on the phototransistor. This interruption then triggers the switch inside the device.

This device can be used in various applications. For example, in automation and robotics, it can be used to detect the presence of a foreign object. In automotive applications, it can be used for detection of open and closed doors or trunk lids, and it can also be used for monitoring whether seat belts are worn. In consumer electronics, it can be used to detect the position of a trackball or a mouse.

The OPB840W11Z comes in a compact package which makes it ideal for use in limited spaces. It is also a low cost device which makes it great for use in cost-sensitive applications. The device is available in two versions: one with logic high output if the slot is occupied, and the other with logic low output. The power consumption of the device is also very low, making it an energy-efficient choice.

In terms of the working principle, the OPB840W11Z is a type of reflective photointerrupter. This means that the light from the photoemitter passes through the opaque slot and is reflected back off the surface of the PCB board. This reflection is then detected on the phototransistor and the switch inside the device is triggered. The detection range of this device is up to 5mm, which makes it ideal for detecting small objects.

The OPB840W11Z also has several features which make it a great choice for a number of applications. It is shock and vibration tolerant, and also has a wide range of temperatures for operation. It is also dustproof and waterproof, which makes it suitable for use in harsh environments. Furthermore, it is RoHS compliant and has a UL 94V-0 flammability rating.

In summary, the OPB840W11Z is an excellent choice as a photointerrupter. It is a compact, low cost, energy efficient device that can be used in a variety of applications. It can also withstand shock and vibration, and is dustproof and waterproof. It also has a wide temperature range and is RoHS and UL 94V-0 compliant. This makes it ideal for use in a wide variety of applications where motion detection is needed.
