Position sensors are used to provide feedback on the actions and position of mechanical components. They can be used to detect the motion of a system whether in terms of linear, rotational, angular, or angular velocity and acceleration. One type of such sensor is the A1334LLETR-60-T which is an angular displacement transducer intended for applications where precise angular measurement is required. This article provides insight into its field of application and explains its working principle.

Application Field

The A1334LLETR-60-T was designed for use in feedback control and other closed-loop systems which require the measurement of small angles with high accuracy. It can be used to measure angular displacement in applications including machine tool axes, robotics, biomass harvesters, 3D printers, and robotic arms. The sensor can measure angles between -60 and +60 degrees with a resolution of 10 amplitude and 0.2 degree per bit. This makes it highly suitable for high-accuracy control operations, such as those mentioned earlier.

Working Principle

The A1334LLETR-60-T utilizes light encoding technology, known as Time of Flight (TOF), to measure angular displacement. The TOF system works by using two light sources and two light-sensitive detectors. The two light sources are set at opposing angles such that when light strikes one of the detectors, it reflects back to the other. This reflection time is proportional to the angular displacement, which is then converted into digital values by the sensor for further processing.

Each of the two light sources in the TOF system modulates the light at different frequencies so as to avoid interference from their respective reflections. The light modulation also helps ensure consistency in the data acquired. The output from the sensor is a Pulse Width Modulated (PWM) signal that varies with the angular displacement. This signal can then be used to control further operations in the system.

Conclusion

The A1334LLETR-60-T is an angular displacement transducer designed for applications requiring high-accuracy measurements of small angles. It utilizes Time of Flight (TOF) technology which uses light sources and light-sensitive detectors to measure the angular displacement of a system. This data is then converted into a Pulse Width Modulated (PWM) signal which can be used to control further operations in the system. The sensor is highly suitable for robotic, machine tool axis, 3D printer, and biomass harvester applications.
