The OPB490L11Z is an optically coupled slot type logic output photointerrupter. This device utilizes a compact slot type package with an IR LED light, a photo detector, and output circuit in a single package. The device is designed to detect the presence of an object in its detection slot.

The OPB490L11Z was designed with an Infrared LED light and a photodetector. The IR LED is an effective source of illumination for the photodetector due to its small size and low power consumption. This allows the device to operate at high operating temperatures. The photo detector within the device utilizes a photo-resistive transducer to detect a change in the light when an object passes through it. The output circuit is designed to output either a logic high or low signal when an object passes through the detection slot.

The OPB490L11Z application field is most often as a switch in industrial and commercial applications. This could be in applications like the detection of mail items passing through an automated sorting system. OPB490L11Z is suitable for indoor or narrow indoor places. This device is often used in conveyor systems as an optical touch sensor when a specific item needs to be detected. It can also be used in vending machine monitoring systems and factory automation.

The typical operating principle of the OPB490L11Z uses a strand of Infrared emitting diodes called the light source and a light-sensitive semiconductor detector with a narrow slot between them. When an object passes through the detection slot, the light from the source is blocked and the detector generates an electrical signal based on the change in light intensity. This change in light intensity causes the output of the device to switch from high to low or vice versa. If the object is of sufficient length, the detector will remain in the blocking state until the object is removed.

The OPB490L11Z is a quick and reliable optically coupled slot type logic output photointerrupter that can be used in a wide variety of applications. Its small size and low power consumption make it ideal for applications where a small sensor is needed and energy efficiency is important. Additionally, the high operating temperatures allow it to be used in harsher environments than traditional mechanical switches. As a result, this photointerrupter is a great choice for industrial and commercial applications that require reliable sensing of objects passing through a detection slot.
