It is popularly used in communication systems, vending machines, document authentication systems, consumer products, and many other industry applications. Additionally, the OPB890T11Z has a number of compatibility features which make it usable within numerous different systems and devices.

Working Principle

The OPB890T11Z is composed of an emitter and receiver, which are both connected to a circuit board, that it is then connected to a power source. The emitter is what emits the light charged with the energy, and the receiver is the part that receives the light and then turns this information into a signal that can be read and interpreted by the various systems that it is connected to. The receiver is located within the face of the device, and in between the emitter and receiver is the slot-type optical sensor that reads the light passing through, to determine if the object has passed or not.

When the power source is switched on, a circuit of light is created between the emitter and receiver. This light is then disrupted and interrupted by a passing object, such as a hand, card or paper, causing the current to be stopped and the light to be extinguished. This disruption in the circuit is then detected by the sensor, and is indicated by a change in voltage in the output signal, with the transistor output showing the specific state of the light, i.e. if it is on or off. This then gives the OPB890T11Z the ability to read any passing object, and turn this knowledge into useful information.

The OPB890T11Z is capable of operating at temperatures ranging from -40℃ to + 105℃, making it a highly versatile device, and can be powered in one of two ways; either through an AC power supply or a DC power supply, depending on the requirements and desires of the user. Furthermore, it has a number of features which reduce the risk of electrical interference, making it a very reliable device.

Conclusion

All in all, the OPB890T11Z is a reliable and versatile slot type optical sensor, equipped with a photointerrupter and transistor output. It has a wide range of applications and can operate in a range of temperatures, as well as being powered in two different ways for ease of use. Furthermore, it is able to detect any passing object and the voltage change in its output signal presents this information. All in all, the OPB890T11Z is a great choice for whatever application it is used for.
