Optical Sensors are devices that are used to detect light or other forms of energy. Photointerrupters are type of optical sensor that is used to detect the presence of an object or detect changes in light. Slot Type photointerrupters use a slot sensor to detect the presence of an object and are commonly used in safety and counting applications. Transistor Output photointerrupters use a transistor output to indicate the presence of an object and are most commonly used in control and automation applications.The OPB821TX is a slot type photointerrupter with a transistor output. It is used for applications where an object must be detected and a signal output is required. The OPB821TX is a contactless device that incorporates a slot shaped light sensor and a transistor output driver. The detector consists of a slot mounted inside a small plastic housing. An infrared LED is placed inside the slot and is used to generate a light beam across the slot. When an object passes through the slot the light beam is interrupted, resulting in a change in the signal output of the transmitter. The signal output is indicated by a voltage level on the emitter.The OPB821TX is designed for applications where a contactless object detection is required. Examples include safety sensor applications such as those used in industrial machinery, automated door openers, and automatic shutters, as well as control applications such as those used for motors, conveyors and other automated equipment.The OPB821TX is designed to be used in situations where a non-invasive object detection is required. The photointerrupter is able to detect a variety of objects including opaque, reflective and non-reflective objects. The device also has a wide field of view so that it can detect objects from a variety of angles and distances.The OPB821TX is designed to be used in a variety of environments including indoor and outdoor, damp and wet, rugged and industrial. The device operates in a temperature range from -25°C to + 85°C and is rated for up to 20 million operations.The OPB821TX has a fast response time of 7ms which is suitable for applications that require a quick response. The device also has a low power consumption and is designed to be energy efficient.The OPB821TX is a durable optical sensor with excellent performance and reliability. The device is also easy to install and is compatible with a wide range of equipment and applications. The OPB821TX is a reliable and cost-effective choice for applications requiring a non-invasive object detection.
