Optical Sensors – Photointerrupters – Slot type – Transistor Output – OPB390L11 application field and working principle are useful for applications such as precision machinery or industrial processes. The OPB390L11 is a slot type photointerrupter with a transistor output, and it has a low on resistance, high saturation voltage, and high-speed response time.

The slot type photointerrupter consists of a phototransistor and a slot in a common cathode package. An infrared light emitted from the phototransistor is concentrated in the slot and it is intercepted by a metal object passing through the slot. When the metal object blocks the light, the phototransistor circuit is opened, which causes the transistor output to switch on. When the metal object passes, the light is no longer blocked and the phototransistor circuit is then closed, which causes the transistor output to switch off again.

The OPB390L11 has a low on resistance of 4.5 Ohms or less that contributes to increased yield in small current circuit applications. It also has a high saturation voltage of 2V (minimum) and 1.4V (maximum) ensuring that it can produce stable and reliable signals. Furthermore, the chip has a high-speed response time of 60µs (maximum) that makes it ideal for fast motion detection applications.

The OPB390L11 can be applied, for example, in auto-feeders where high accuracy is essential. In an auto-feeder, the chip can be mounted on the machine’s frame and a metal object is inserted in the slot in order to trigger the phototransistor circuit. When the metal object passes through the slot, the transistor output is switched on and off. This is useful for functions such as detecting when the metal object has reached the end of its travel, or when it has reached a certain position.

Another application for the OPB390L11 is in conveyor belt systems. In this case, the slot is mounted on the belt and a passing metal object triggers the phototransistor. This can be used to detect changes in the movement of the belt, such as when it is overloaded or when it needs to be stopped and restarted. Additionally, the chip can also be used to detect the presence of non-metallic objects on the belt, or the direction in which the belt is moving.

In summary, the OPB390L11 is a slot type photointerrupter with a transistor output, and it is suitable for applications such as detecting metal objects on a conveyor belt or in an auto-feeder. It has a low on resistance, high saturation voltage and high-speed response time, making it an ideal choice for precision machinery or industrial processes.
