Optical sensors are devices that detect and measure light. Photointerrupters are devices that detect the interruption of a light beam. They are commonly used in industrial and commercial applications, particularly for safeguarding moving objects or automated systems. The OPB848TXV is a slot-type photointerrupter with transistor output.

Application Field of OPB848TXV

The OPB848TXV is a high reliability, high speed transistor output photointerrupter with two channels (an emitter and a detector). It is suitable for a wide range of applications, such as proximity sensing, visual adjustment of objects, detection and control of motor speed and direction, and any other applications that require accurate, reliable detection of interruption of light. This photointerrupter is especially suitable for applications that require a large dynamic operating range, such as automatic assembly and sorting applications.

Working Principle of OPB848TXV

When EMITTER is illuminated by the light source, the REF terminal signals a voltage drop, which triggers the transistor output stage and causes Q1 to turn on. When a slot-shaped object interrupts or shades the light beam between the emitter and the detector, the REF voltage will rise to close the transistor output stage, and Q1 will be switched off. The position of the slot-shaped object relative to the emitter and detector is determined by the voltage difference of the REF terminal.

The OPB848TXV also has a noise rejection capability. Its built-in noise filters can reject high-frequency noise, protecting the device from external interferences and keeping the device running smoothly and reliably. The device has a wide operating voltage range (from 5V to 24V DC), ensuring that the output voltage signal is not distorted by supply voltage.

Overall, the OPB848TXV is a reliable and efficient photointerrupter with a wide range of applications. Its integrated noise rejection technology and wide operating voltage range make it suitable for a variety of industrial and commercial applications.
