Introduction to OPB741WZ

The OPB741WZ is an optical sensor manufactured by Honeywell of the Reflective ˜ Analog Output type. It consists of through-beam and retro-reflective configurations, a phototransistor receiver, support circuitry, and a lead frame package. This reflective optical sensor uses a special coating to provide an invisible return beam when a light source is reflected back to the sender. The OPB741WZ sensing system is composed of an emitter, lens and receiver. The emitter emits an infrared beam, and the lens projects it on to the object whose presence is to be detected. The return beam is detected by a receiver and converted into a proportionally current or voltage output.

Application Area

The OPB741WZ optical sensors are used in a variety of applications, ranging from industrial machines and motion control devices to automotive systems. The OPB741WZ is suitable for use in portable and fixed type automation machines, where it can be used to detect the presence or absence of objects, like boxes, bins, containers, etc. At the same time, it is also suitable for use in automated production lines and various automotive systems. Moreover, the sensor also finds application in different motion control applications, like robots, conveyors, and various machines used in industries like food & beverage, pharmaceutical, automotive, etc.

working principle

The OPB741WZ sensor consists of an emitter led and a photodiode receiver. It works based on the strength of the reflected light detected at the receiver when an object is close to the sensor. When the light is not reflected back, it is considered that the object is not present. Thus, it is mainly used to detect the presence of moving or stationary objects. The OPB741WZ is capable of detecting small objects, due to its high resolution. The sensed signal is amplified by the support circuitry and is outputted either as a current or a voltage signal depending upon the configuration.
