Introduction

OPB390N51Z is an opto-coupler family of digital output slot opto-interrupters that offers precise digital printing, data communication isolation, and switching functions. OPB390N51Z is a Photointerrupter from Omron Corporation used for a variety of detection, sensing, and counter applications. It utilizes a slot type optical system to detect the passage of an object through the light/dark area transition. This emits an ON/OFF signal through the transistor output.

Features

• Highly reliable construction: This opto-interrupter is hermetically sealed with a protective resin to mask against dust and contamination.
• Accurate switching: This high-speed signal ensures that no target motor surface is damaged.
• Compact: This compact size is suitable for limited space applications.
• Wide detection range: OPB390N51Z can be used to detect a range of objects including paper, rubber bands, CDs, and plastic seals.

Application Field

The OPB390N51Z is a versatile digital opto-interrupter that can be used for a range of applications including:

• Home appliances: OPB390N51Z can be used for counting food, diapers, paper, and other small parts and objects in home appliances.
• Product processing control: This opto-interrupter can be used to detect paper size and enables precise printing alignment.
• Data communication isolation: This feature limits the amount of distortion in data transfer from one device to another.
• Sensing and counter applications: This opto-interrupter can be used for sensing and counting paper, objects, and other items.
• Switching Functions: OPB390N51Z can also be used for high-speed switching to ensure that no target motor surface is damaged.

Working Principle

The slot type optical system used in OPB390N51Z works on the principle of a gap crossing. This is a method of using light to detect the movement of an object, usually a paper sheet, through a gap crossing. The gap crossing is designed such that it emits a laser beam from the source to the optical receiver. When the object passes through this gap, the laser will be interrupted, and the transistor output will be turned ON and OFF accordingly.

Conclusion

The OPB390N51Z is a compact opto-interrupter developed by Omron. It has a robust construction which makes it highly reliable. This opto-interrupter works on the gap crossing principle to detect any object, including paper, rubber bands, CDs, and plastic seals. In addition, it can be used for counting, printing, data communication isolation, and other switching functions. The OPB390N51Z can be used for a range of applications in various industries.
