Optical Sensors are devices that detect changes in optical signals in order to measure or detect physical conditions. Photointerrupters are a type of optical sensor that measures physical conditions by the interruption of a light beam. Slot Type is a type of photointerrupter that signals the interruption/resumption of a light beam when a slotted wheel passes in between the light source and detector. Transistor Output is a type of photointerrupter with transistor output, which uses a light-blocking plate to turn the transistor circuit ON and OFF.

OPB680 is a specific type of transistor output photointerrupter and a popular choice for applications requiring high speed signal sensing. It has a common package size of 5.1 x4.5 x1.5 mm and is built with a plastic housing to ensure long-term dependability and durability in harsh environments. The OPB680 has a maximum input voltage of 5V and a maximum operating power of 100mW. It is compatible with most integrated circuits and has a maximum switching frequency of 2 KHz.

The working principle of the OPB680 is quite simple. When the signal input is ON, the light is emitted from an infrared LED and passes on to a phototransistor. As the light is blocked, the signal from the phototransistor is turned off. This turns off the transistor output circuit, making the OPB 680 close. Conversely, when the signal input is off, the light beam is unblocked and the transistor output circuit is turned on, making the OPB 680 open.

The applications of the OPB680 are wide and varied. It can be used in proximity sensors, position-sensing switches, smoke detector alarms, and door locks. It can be used to detect the presence of objects in an automated assembly line. It can also be used to detect presence and absence in an optical fiber communication system. It is also used in challenging industrial applications, including oil and gas installations, where it can be deployed to detect the presence of oil and gas pipelines.

The OPB680 is an ideal choice for deployments requiring reliable operation and high-speed response. This low-cost solution is cost-effective and its short response time makes it suitable for applications requiring high-speed signal sensing. It is also easy to install and can be used in both new and existing applications, making it a great choice for industrial applications where precise and reliable operation is a must.
