OPB697C

Optical Sensors are devices which detect light and generate an electrical signal in response to a change in light intensity. Among them, Photointerrupters are a specific type of optical sensor which emits an electric potential when interrupted by a beam of light, which can then be used to detect objects or cues. These sensors can be used in automated machinery, video game systems, and laser printers. Among Photointerrupters, Slot type sensors are the type which have a slot that when a beam of light passing through the slot is broken, it will generate an electric potential. The OPB697C is a Photointerrupter and slot type sensor with a logic output, designed to quickly, easily, and reliably detect the presence of an object passing through the slot.

The OPB697C is a slot-type photo-interrupter and is available with either a normally open or normally closed transistor output. It consists of an opaque slot with an LED on one side and a phototransistor on the other, housed in a 12-pin plastic package with heat-dissipating mounting brackets. Both the LED and the phototransistor are encapsulated in the housing, so they are shielded from the environment yet still separated by the stone slot. The unit is also designed to be durable, being able to withstand shocks and vibrations.

When an object passes through the slot, the LED emits a beam of light that is then cut by the object, and the transistor quickly releases the corresponding signal. As the LED and phototransistor are separate, there is no worry about any overlap in the light spectrum from either part. This type of sensor is widely used for automated machinery in industrial applications, laser printers, and other video game systems. In industrial applications, most of these interrupters are integrated into various types of machinery, such as conveyors, textile machines, and printing machines, to ensure reliable detection of objects. In laser printers, the interrupters detect the presence of paper, toner, or other objects in the printer and generate a logic signal to control the printer.

The working principle of the OPB697C is based on the fact that the LED emits a beam of light that is then cut by the object. This results in the transistor quickly releasing the corresponding signal that is used to generate a logic signal. The logic signal can then be used to control the respective device, such as a conveyor belt or a printer. The setup of the OPB697C makes it very easy to mount, as it only requires a 12-pin plastic package and heat-dissipating mounting brackets. This makes it a great choice for various industrial applications, as well as other video game systems and laser printers.

In conclusion, the OPB697C is a slot sentry with a logic output and is used to quickly and easily detect the presence of an object passing through the slot. This type of sensor is used in various industrial applications such as conveyors, textile machines, and printing machines. It is also commonly used in laser printers and other video game systems. Its easy setup with a 12-pin plastic package and heat-dissipating mounting brackets makes it a great choice for many different applications.
