OPB390L55

Optical Sensors -Photointerrupters -Slot Type -Transistor Output

The OPB390L55 is an optical sensor which utilises slot type photointerrupters with transistor outputs. This type of photointerrupter works by using a light emitting diode which is placed in a small slot, and a transistor which is located opposite the LED to detect the light signal. The light signal is used to control and detect the presence of an object relative to the LED and the transistor.

Application Field

The OPB390L55 is designed for use in a range of different industrial and consumer applications, including but not limited to automotive, medical and industrial process control. As this photointerrupter operates with a transistor output, it can be easily integrated into existing systems or connected to other electronic systems. It is also suitable for high speed applications due to its fast response time.

Working Principle

The OPB390L55 uses a slot type photointerrupter with transistor outputs which works to detect the presence of an object. The light emitting diode (LED) is placed in a small slot, while the transistor is placed opposite it. When an object passes through the space between the LED and the transistor, a signal is generated which is detected by the transistor and converted into an electrical signal. This signal can then be used to control and detect the presence of the object relative to the LED and the transistor.

In order to ensure reliable operation, the OPB390L55 is equipped with several features which help to reduce the effects of electromagnetic interference and ambient light. For example, a built-in light shield helps to reduce the effects of ambient light, while a Zener diode helps to protect the device from surges of current. Additionally, the OPB390L55 is designed with a wide operating temperature range (up to 125°C) which allows it to be used in a variety of different environments.

Conclusion

The OPB390L55 slot type photointerrupter with transistor outputs is a reliable and robust solution for a range of industrial and consumer applications. Its fast response time and features for reducing electromagnetic interference and ambient light make it ideal for use in high speed applications. Additionally, its wide operating temperature range (up to 125°C) makes it suitable for use in a variety of different environments.
