OPB891L55Z

Introduction

The OPB891L55Z is an optical sensor from the photointerrupter family, a type of optical sensor that has been developed to detect the interruption of an optical beam using a light barrier. It is a slot-type, with a transistor output, which makes it ideal for a number of applications such as converting rotary motion into electric signals. This particular model is a high precision device with long lifetime, and benefits from the features of a compact package with a wide-angle detector.

Application Field

The OPB891L55Z is typically used in applications related to motor control as well as pulse measuring and Position sensing. It is specifically designed to measure the position of moving objects such as those performed in motor control or other precision applications. Its high precision, long lifetime and small form factor makes it ideal for applications where motion sensing accuracy, reliability and size are of crucial importance. It is also suitable for use as a feedback device in combinations with other detectors or encoders.

Working Principle

This photointerrupter uses a light barrier to detect interruption of an optical beam. It consists of an emitter and a detector. The emitter is coupled to a DC power supply, which generates a light beam that is then transmitted towards the detector. When the light beam is interrupted, for instance when an object passes through the photointerrupter, the detector produces an output signal. The output signal is then processed by the application’s control module, which interprets it and performs the desired action.

The detector of the OPB891L55Z features a small-angle, wide-angle detector, which allows its accurate detection in applications where the object cannot stay in the same position for an extended period of time. This makes the device much more accurate than traditional photointerrupters which require the object to remain in the same position for the duration of the sensing operation.

Advantages

The OPB891L55Z offers a range of advantages over traditional photointerrupters. These include:

• It provides improved resolution and accuracy over traditional photointerrupters
• It is smaller and more compact than traditional photointerrupters
• It has longer lifetime due to its improved design
• It is suitable for use in applications where motion sensing accuracy is of crucial importance.

Conclusion

The OPB891L55Z is an optical sensor from the photointerrupter family, a type of optical sensor that has been developed to detect the interruption of an optical beam using a light barrier. It is a slot-type, with a transistor output, which makes it ideal for a number of applications such as converting rotary motion into electric signals. This particular model is a high precision device with long lifetime, and benefits from the features of a compact package with a wide-angle detector. It is most suitable for applications related to motor control as well as pulse measuring and Position sensing.
