OPB890T51Z

Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The OPB890T51Z is a transistor output photointerrupter, which belongs to the slot type photointerrupters. It is composed of an infrared emitting diode and a photosensor in a single package with an insulation distance of 2.5mm. It is widely used in various applications due to its low cost and fast response time.

Application Field

• The OPB890T51Z is mainly used for pulse signal generation in various equipment such as camera shutters, hard disk drives, CD players, paper feeders, motors, transmitters, television/VCR remote controllers, etc.
• It can also be used in industrial and commercial applications such as robotics, transportation system, fire detection, etc.
• It can also be used to detect the presence or absence of objects in a specific area.

Working Principle

The working principle of OPB890T51Z is simple and straightforward. It consists of a phototransistor and an infrared LED, which are mounted on a printed circuit board. When an object passes through this gap between the LED and the phototransistor, the LED will emit a light beam which will be detected by the phototransistor and the output will be driven to a low voltage level. This change in voltage will act as a signal that the object has been detected. The response time of the OPB890T51Z is fast and can be used for applications where reliable and quick response is needed.

Advantage

• The OPB890T51Z is easy to use with its simple design and easy installation.
• It is highly reliable due to its long life span.
• The detection range can be adjusted to different application requirements.
• Its fast response time makes it suitable for industrial and commercial applications with a high speed.
• It is also very cost effective.
