Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The OPB390T51Z is an industrial grade photointerrupter designed for a range of applications such industries as automotive, communications, electronic ballasts, consumer, industrial, and instrumentation equipment. This photointerrupter is a versatile optoelectronic device that can be used to sense the position of a moving object or the presence of an object in a slot or gap. It can be used in applications requiring improved resolution, short response time, and reliability compared to other status-sensing technologies.

Application Field

The OPB390T51Z is designed to detect the presence of a gap or slot in an industrial environment. For this task, two infrared light emitting diodes emit light onto the slot while an optical detector receives the light. By measuring the amount of light received, the OPB390T51Z can detect the presence or absence of the slot. This type of device is commonly used in factory assembly lines, conveyor systems, and automation systems.The OPB390T51Z is also designed for use in industrial robot motion control and automation systems. This device can detect the precise position of an object in an X/Y plane or the presence of a gap in a tight tolerance application. By detecting a gap or slot, the OPB390T51Z can be used in robots to track the motion or switch control signals.

Working Principle

The OPB390T51Z consists of two infrared LEDs and an optical detector housed in an aluminum case. The LEDs transmit infrared light that passes through the slot or gap into the detector. By detecting the amount of light reflected from the slot, the OPB390T51Z can determine if there is a gap or slot present. The device is designed to have a high DC current gain, low distortion, and quick response.The OPB390T51Z has a compact design, making it ideal for space-constrained applications. It can be mounted horizontally, vertically, or directly to a substrate surface. The device has a wide operating temperature range, making it suitable for numerous applications in extreme environmental conditions.The OPB390T51Z features a high power gain, with a maximum of 500mV and a maximum output current of 30mA. The optocoupler is highly sensitive, with a low operating voltage of 4V. The optical detector has a wide viewing angle of 110° and a wide range of operating temperatures.

Conclusion

The OPB390T51Z is a versatile optoelectronic device designed for a range of applications in industrial automation, motion control, factory assembly lines, and conveyor systems. The OPB390T51Z features a compact design, high DC current gain, low distortion, and a wide operating temperature range. Its two infrared LEDs emit light onto a slot or gap while an optical detector receives the light and determines the presence or absence of the gap. Overall, the OPB390T51Z is a reliable device that can provide users with precise position sensing and gap detection.
