OPB980L55 Application Field and Working Principle

Today, we are living in the world of automation. No matter it is in industrial metallurgy, packaging, or digital platform, there is no doubt that automation has drastically changed the ways in which our society lives and functions. And for all these automation activities, optical sensors play an important role. Among them, photointerrupters, and in particular, slot type like the OPB980L55, are the key elements for helping automation control systems achieve higher accuracy and safety.

The OPB980L55 is a slot type photointerrupter with logic output. It is a two-button photoelectric switch that works by sensing an object passing through its active surface. It is a non-contact optical switch designed to enable contact-free switching with a good response time of 5ms. It is also very compact and lightweight in design and offers excellent reliability. The package is a 6-pin DIP (Dual Inline Package), with direct PCB mountable and through-hole assembly.

The OPB980L55 is ideal for a wide range of applications in automation. It can be found in many industrial control systems, such as on conveyor belts and in pick-and-place machines. It also finds application in medical systems, building automation, security systems, digital platform automatic control, and much more. In addition, it is also widely used in consumer electronic products such as smartphones, tablets, and wearable devices.

The working principle of the OPB980L55 is based on the interaction of light transmitted from an LED (Light Emitting Diode) to a phototransistor. The OPB980L55’s visible red light emitted from the LED acts as a transmitter of RF energy from the switch. When an object passes through the active area directly beneath the LED, it interrupts the light and triggers the phototransistor, which is connected between the anode of the LED and the transistor. As soon as the sensor’s output line changes from a Low signal to a High signal, the logic output will be switched off.

The OPB980L55 is a reliable, cost-effective, and easy-to-use photointerrupter. It can be used in a variety of applications, including industrial, medical, building automation, and consumer electronic systems. In addition, its excellent response time of 5ms, low power consumption, and robust construction make it an ideal option for automation control solutions.
