Optical sensors are devices that detect light and convert it into a signal that can be used for various applications. Photointerrupters are one type of optical sensor that is used to detect the presence of or change in the intensity of light. The OPB490P11 is a type of photointerrupter that is specifically designed for applications requiring a slot-type logic output. This section will discuss the typical application field and working principle of the OPB490P11.

The OPB490P11 is a logic output-type photointerrupter, consisting of a GaAs infrared emitting diode optically coupled to a phototransistor. The OPB490P11 has a detection range of 0.5 mm to 0.6 mm and a response time of 1 µs. It is suitable for a variety of applications such as sensing of roller or disk encoders, presence/absence of components in automated machines, and analysis of paper documents.

In terms of the working principle, photointerrupters are optical switches that switch from an on-state to off-state when the optical path is interrupted by an object or light source. The OPB490P11 is designed to be slot-type, meaning that it consists of two parts – an optical source such as a LED (Light Emitting Diode) and a receiver such as a phototransistor. The LED emits infrared light that isreceived by the phototransistor when an object passes between them, and this interruption of the light causes an output switch.

When an object passes through the slot, the optical path is interrupted and the output from the phototransistor to the LED is cut off. This change in the optical path causes a change in the electrical current which then causes an output switch. In other words, if the output switch is active (in the absence of an object in the slot) then the output switch will be switched off when an object is present in the slot. This is the basis of the OPB490P11’s operation.

Essentially, the OPB490P11 is designed for applications that require a logic output type photointerrupter. Its wide detection range, fast response time, and low power consumption make it an ideal solution for a variety of industrial and commercial uses. Its normal operating voltage range is between 5V and 24V, making it suitable for direct use with microcontrollers. Additionally, its high-sensitivity phototransistorsensor ensures reliable and accurate sensing over a wide range of distances.

Overall, the OPB490P11 is a slot-type photointerrupter with a logic output that is designed for applications requiring accurate and fast sensing of a wide range of distances. It is suitable for usage in industrial and commercial applications such as sensing of roller or disk encoders, presence/absence of components in automated machines, and analysis of paper documents. Its wide operating voltage range, fast response time, and high-sensitivity phototransistor sensor make it an ideal option for many applications.
