The OPB855, a type of photointerrupter sensor, belongs to the slot-type with transistor output category of optical sensors. It detects the presence or absence of an object in a gap of such a size that the optical signal is interrupted or allowed to pass through. When the object blocks the gap, the photointerrupter will detect this and produce a voltage, allowing the engineer to control, interpret, and execute commands accordingly.
This photointerrupter’s slot width is 0.8mm, with an operating voltage range of between 4.5 and 10.5V. The optical-axis emitter uses an IGBT output circuit, and a current transfer ratio of 0.7, with an output voltage of 2.5V. It also has a dark-ON operation, which means the output is "on" when the gap is blocked.
The OPB855 is used in various fields due to its slim profile and high operation precision. It has been used for years in industrial automation, such as conveyor belt control, factory-floor quality inspection, printing presses, and vending machines. Paper media sorting machines use photoelectric sensors for their detection, and the OPB855 is popular in this field. It is also used for multi-purpose systems, such as machinery output control, PLC inspection, and failure detection systems.
On top of the industrial applications, innovation is now bringing the OPB855 to the consumer side, with potential uses in self-driving cars, obstacle avoidance navigation systems, and automated garbage sorting machines.
The OPB855 works by producing pulses when the gap is blocked, thus allowing a current to pass, and by using this alternating current, engineers can determine the presence of an IR emitter. This allows the OPB855 to act as both a pass-through detector and a switch system when the optical signal is blocked. The IGBT circuit then amplifies the signal and ensures the output voltage is maintained at an optimum level.
As for installation, the OPB855 is designed to fit into tight spaces and can even be mounted directly to the equipment without the need for additional hardware. It is simple to operate and requires minimal maintenance, and is also a reliable, inexpensive, and cost-effective choice for many applications.
Overall, the OPB855 is a reliable photointerrupter with a wide range of applications. Its slim profile and high operation precision make it an excellent choice for industrial and commercial uses. Its easy installation and maintenance requirements make it a cost-effective solution, ensuring engineers can get the most out of their device.
