Optical Sensors are becoming increasingly important in modern electronic applications, especially those that require precise, low-power, switching or signal detection. Photointerrupters are one type of optical sensor, and the OPB690Z is a particular type of Photointerrupter. Specifically, the OPB690Z is a Slot Type Transistor Output Photointerrupter. In this article, we will discuss the application field and working principle of this device.

Application Field

The OPB690Z is a miniature slot-type optical sensor that is used in a wide variety of applications, including gaming machines, consumer electronics, automobile body and safety systems, home appliances, and industrial equipment. It is also often used in security applications such as burglar alarms and access control systems.

The OPB690Z is designed to be used in situations where there is not much space, as it is extremely small and has low height and profile., It is also designed to be resistant to vibration and impact, meaning it can be used in operational environments where mechanical shock is a factor.

The OPB690Z is capable of switching operations over a wide range of frequencies, making it ideal for high-speed switching applications. Additionally, it has a low power consumption, which makes it ideal for battery-powered applications. Finally, the OPB690Z is capable of detecting objects over a wide range of distances and angles, allowing it to be used in automated control systems.

Working Principle

The OPB690Z is an NPN-transistor output optical sensor, which means it can act as an on-off switch when a light-emitting diode (LED) chips facing the slot of the device is blocked or unblocked. This is done thanks to the OPB690Z’s internal IR-LED and phototransistor, which work together to detect the presence or absence of an object in the slot.

The OPB690Z’s internal IR-LED is powered by an internal voltage source, so there is no need to externally supply power to the sensor. The IR-light emitted by the LED is directed into the slot in the OPB690Z and when an object is placed in the slot, the IR-light is blocked, which triggers the internal phototransistor. The phototransistor, in turn, sinks the voltage that is applied to the OPB690Z’s output transistor, resulting in a low voltage at the output. When the object is removed from the slot, the output voltage returns to its original high level.

The OPB690Z also has a long-range sensing capability, meaning it can detect objects up to 50mm away. This makes the OPB690Z ideal for applications where the object being detected is outside of the slot.

The OPB690Z is a robust and reliable optical sensor, and is capable of switching up to 5000 cycles per second. It is also capable of detecting a variety of objects, from transparent materials to metal objects. Finally, due to its small size and low-power consumption, it is ideal for battery-powered applications.

Conclusion

The OPB690Z is a Slot Type Transistor Output Photointerrupter, designed for a wide range of applications. It is capable of switching operations over a wide range of frequencies, and has a low power consumption. It is also robust and reliable, capable of detecting objects over a wide range of distances and angles. Finally, due to its small size and low-power consumption, it is ideal for battery-powered applications.
