OPB695C is an optical sensor of the slot type which uses two selective optical components: an emitter opto-coupler and a receiver opto-coupler. This type of opto-coupler works by using the transmission of a light beam from an emitter through a separation slot to the receiver.

Operating principles of the OPB695C comprise two stages of manufacture: the first being the emitter and receiver being housed in a single package, and the second is the production of a light assist slot in the package. During operation, the transmission of the emitted light beam between the emitter and receiver is blocked by the slot. When an object breaks this slot, the direct line of transmission is open and the output state indicator will be switched ON.

The OPB695C optical slot sensor provides superior reliability and offers immense flexibility for a range of applications. This device operates with high switching frequency and low power consumption as a result of its extremely low fan-out capability. Furthermore, the OPB695C has a superior signal-to-noise ratio and therefore outstanding immunity to noise compared to other optical slot sensors.

The most suitable and common application for the OPB695C is a short-range proximity sensing application. With its low power consumption, high switching frequency and compact design, the device is capable of detecting objects accurately and reliably in close proximity. In this way, the OPB695C is widely used in short-distance sensing applications such as switch actuation, surveillance systems, remote door access, and collision avoidance systems.

In addition to short-range proximity sensing applications, the OPB695C can be used in more complex applications such as the detection of small objects using background suppression like in industrial counting systems. This application requires the use of the slot to be temporarily filled with a suitable material before the object can be detected. This may include the use of paper, fabric, card, or any other material that is capable of being detected by the OPB695C. Once the material is positioned in front of the OPB695C, the device will detect the presence of the object and will switch its output accordingly.

The OPB695C is also commonly used for edge and corner detection in automated processing systems. This type of application requires the device to detect the shape of an object as well as its position in order to avoiding collisions and possible hazards. The slot created by the OPB695C will detect the edges and the corners of objects where it will then generate the appropriate response.

Finally, the OPB695C is capable of directional detection as well. This is achieved with the use of a light beam reflector on the object in order to return the light to the sensors output. This application makes it possible to detect objects in a directional manner combined with the same high precision as it would be in a non-directional operation.

In conclusion, the OPB695C is a logical output optical sensor of the slot type. It combines low power consumption, high switching frequency and excellent signal-to-noise ratio. The device is capable of detecting objects in a wide range of applications such as switch actuation, industrial counting systems, corner and edge detection, remote door access, and directional detection.
