Optical sensors are devices that detect the presence of a target or a pattern of a target based on the scattering of light from a light source. Photointerrupters, a type of optical sensor, are specifically designed to detect the interruption of light within a specified area. The OPB960P55 is an example of a photointerrupter. This device is designed to detect the interruption of light in a slot-type area with a logic output.

The OPB960P55 optical sensor is a 3-pin device. It consists of an emitter, a receiver, and an output. The emitter is an infrared LED, which emits light when a positive voltage is applied. The receiver is composed of a PIN photo-diode which detects the amount of light that is scattered in the sensing area. The output of the device is a digital logic signal that is high when a light is detected and low when no light is detected.

The OPB960P55 is designed to detect a specific slot-type area. It is a through-beam type photointerrupter, meaning that a light beam is transmitted through a sensing area and the interruption in the light beam indicates the presence or absence of a target. The device has a sensing range of 8mm and operates over a range of 10 to 30V. It has a response speed of 6μs and an emitter output power of up to 100mW. The device is available in either a DIP-4 or a surface-mount package.

The OPB960P55 is used primarily in industrial sensing applications. Examples of application fields include the sensing of moving parts in automated machines, detection of paper or other objects in printing or packaging machines, and communication systems. It is also used in motion control and pick-and-place systems.

The working principle behind the OPB960P55 is very simple. When the infrared light is emitted from the emitter, it travels through the slot-type sensing area and is detected by the receiver. If an object is in the sensing area, it will block the light, resulting in an interruption, which allows the output to be detected. If no object is present, the light will pass through the sensing area, and the output will remain low.

In summary, the OPB960P55 is a slot-type photointerrupter with a logic output. It is primarily used in industrial sensing applications and operates by detecting the interruption of light. The device consists of an emitter, a receiver, and an output, and has a sensing range of 8mm and a response speed of 6μs. With its small size and low power consumption, the OPB960P55 is simple, cost effective, and reliable.
