Optical sensing devices are used to detect changes in light in order to measure variables such as light intensity, distance and motion. The OPB607A is an optical reflective sensor, capable of providing analog output and used to measure changes in light levels in order to determine distance, speed and displacement.

The OPB607A consists of an infrared (IR) emitter and an IR receiver placed on the same axis. IR light is emitted from the emitter and reflected from the target back to the receiver. When the target is too far away, reflecting light back to the receiver is insufficient and the output signal is low, and vice versa for when the target is at a close distance.

The analog output of the OPB607A is determined by the measured reflective light. This analog output range can be adjusted via potentiometers. The type and tiny size of the package make the OPB607A an ideal solution for integration on most surfaces. The system design allows the OPB607A to be easily used with long and short working distances, depending on the conditions of the target surface.

The OPB607A is typically used in medical, industrial, consumer and automotive applications. In medical applications, the OPB607A is used to monitor the safety of surgical tools, allowing medical staff to quickly and accurately check that tools are present and safe. In industrial applications, the OPB607A is used as a distance sensor to measure the thickness of specific materials. In consumer applications, the OPB607A is used in digital cameras to accurately focus images. In automotive applications, the OPB607A is used to measure the distance between the car and obstacles or other vehicles.

The OPB607A uses an advanced optical sensing technology that is based on infrared emission and photodetection. Its infrared receiver will detect the presence of any reflective surfaces, and the integrated analog output is used to measure the position and the working distance. The emitter is a high intensity IR LED which is driven by a current between 5-30mA, and operates at a carrier frequency of 1 MHz and a duty cycle between 5-96%. The receiver is composed of an array of photodiodes, and the signal is amplified by CMOS circuits before being converted into a voltage output.

The OPB607A has an adjustable working distance range of 1-50 cm, with an accuracy of 0.1 cm and a resolution of 0.1 cm. It has a detection range of 0-255 mm and a maximum working speed of 20 cm/s. The maximum range is modified based on the strength of the reflective surface, and optimal performance can be achieved when the target is a white surface. The operating temperature range is -20 to +70 degrees Celsius.

In summary, the OPB607A is an optical reflective sensor with analog output that is capable of accurately measuring distances up to 50 cm. It is suitable for use in medical, industrial, consumer and automotive applications. Its small size and adjustable working distance make it an ideal solution for integration on most surfaces.
