Optical sensors allow for the detection and measurement of the amount of light that passes through its target area. The OPB841W51Z is a specific type of optical sensor in the Photointerrupter – Slot Type – Transistor Output family. It performs precision measurements of low-intensity light sources, and the output can be programmed to match the electrical requirements of the circuit it is connected to.

The OPB841W51Z is a reverse-mount, rectangular-shaped photodetector that functions on the interruption principle. It is composed of a source light-emitting diode (LED) and a silicon phototransistor. The two components face each other within an insular outer casing, which is transparent to visible and infrared light. The light that is emitted by the LED passes through an opaque membrane with a slit in the center. When the slit is in line with the phototransistor, the light will be interrupted and turn off the phototransistor. As the membrane rotates, the slit passes in and out of the line of sight of the phototransistor, causing it to be periodically turned on and off, producing a continuous output signal. The membrane rotation should be adjustable, so that the width of the slit, and the length of time that it is in line with the phototransistor, can be adjusted.

The OPB841W51Z has a variety of applications. It can be used for motion control of automated machinery, as it provides an accurate and reliable detection of rotational alignment and speed. The OPB841W51Z is used extensively in the printing industry, as they can easily detect occlusions on the print head, as well as detect alignment faults in the media transport system. Additionally, the OPB841W51Z can be used in a variety of security systems, as it can detect intrusion into restricted areas by breaking the light-emitting beam.

The OPB841W51Z is designed to be extremely reliable in operation. The optic parts are constructed from a high-grade polymer, which makes them resistant to shock, wear, and corrosion. The electronics are also designed to maintain their settings over a range of temperatures, reducing the need for frequent calibration. This ensures the sensor’s accuracy and reduces maintenance costs.

When the OPB841W51Z is connected to its circuit, the LED generates an infrared beam that passes through the membrane. When the slit opens, the phototransistor breaks the signal. This break signals the control circuit to turn on or off the device. The control circuit can also be programmed to react differently to the output of the OPB841W51Z. For example, it can be programmed to ignore occasional short breaks, and only react to sustained interruptions in the signal.

The OPB841W51Z is a versatile and reliable optical sensor. It is designed to detect small differences in light sources, and can be programmed to react to varying illumination levels by changing its output signal. It is rugged and reliable, and able to withstand a wide range of temperatures and environmental conditions. These features make the OPB841W51Z capable of performing in many different applications.
