OPB350W250Z

Optical sensors are devices which use light to detect the position, movement or presence of objects. Photointerrupters, a type of optical sensor, detect the presence or absence of objects or changes in a light signal by converting the light into electric signals. The OPB350W250Z is an example of a slot-type, transistor-output photointerrupter optimized for use in a wide variety of applications.

Features

The OPB350W250Z has a small profile design, combining both a detector and a surface-mounted emitter. The light receiving portion of the OPB350W250Z is a high-sensitivity NPN phototransistor type, giving it fast switching times and low power consumption. The emitter portion is a high brilliance infrared halo type LED, able to work in a wide range of environmental conditions.

The OPB350W250Z has a very small form factor of 4.5mm x 19.8mm x 5.0mm. It is designed to be highly reliable with high sensitivity and stability in harsh environments. It also offers excellent EMI performance, allowing it to be used in areas with high levels of EMI present. Its insulation is rated at 250Vrms, and it can be operated from a supply voltage of 5V DC.

Application Fields

The OPB350W250Z has a wide range of applications in areas such as industrial control, medical equipment, sensing and automation. It could be used to detect the presence or absence of an object quickly and reliably. It can also be used for a range of other measuring tasks, such as counting revolution, detecting speed, or recognizing color and patterns.

The OPB350W250Z can be used in a variety of environments, including indoor applications, as well as out of doors, where its high efficiency makes it well suited for applications like obstacle detection and material handling. It can also be used in machines with high levels of EMI, due to its excellent EMI performance.

Working Principle

The working of the OPB350W250Z can be broken down into two stages: the emission and reception of light. First, the LED emits an invisible infrared light, in a narrow beam. This beam is then disrupted by an object, such as a finger, which interrupts the flow of light. The interrupted signal is picked up by the built-in sensing circuit, which produces an electric signal indicating that an object is present.

The emitted infrared light then passes through the emitter lens and reflects off the object. The reflected light is then captured by the sensor, which converts the altered signal into an electrical signal. This signal is then sent to the control circuit, which can respond to the presence of the object.

Conclusion

The OPB350W250Z is a versatile and reliable optical sensor, which is suitable for a variety of applications. It is highly sensitive and can be operated in a wide range of environmental conditions. It also has excellent EMI performance, making it well suited for areas with high levels of electromagnetic interference. It is a compact, cost-effective solution for sensing and automation tasks.
