Rotary Potentiometers, Rheostats

PTM902-020K-204A2 is an electrical device that transforms rotational motion into a change in electrical resistance, or a so-called rotary potentiometer or rheostat. In its simplest form the device is constructed of a resistive element mounted inside a rotatable shaft. As the shaft is turned, the orientation of the resistive element to the electrical contacts is changed. This causes the resistance between the contacts to vary.The PTM902-020K-204A2 device utilizes a long-life, low-drift silicon strain gauge resistor element which is driven by a shaft. As the shaft is turned, the shaft wheel drives a gear wheel which in turn moves a tautly drawn conductor over the resistor element. The motion of the conductor over the fixed strain gauge element causes a proportionate change in the electrical resistance as the conductor is moved through an arc of 40° approximately from full clockwise (CW) to full anti-clockwise (ACW).Due to a perfectly symmetrical torque output, the potentiometer is also known as an equal angular rotary rheostat. This type of device is simple in design and able to absorb short-term over-currents or polarity reversals.The PTM902-020K-204A2 has a wide range of applications that involves movement sensing, angle measurement and some control systems. It can be used in different industries such as Chemicals, Papers & Paints, Heavy Engineering, and Household & Automotive. In industrial applications, this device can be used as a standard feedback input for proportional and integral controllers. It is widely used in material handling machines such as conveyors, elevators, mixers, and other automated systems. As a result, the sensing device translates a rotational movement into electrical signals. The timing gradients can be adjusted accordingly to increase or decrease the speed accordingly.The PTM902-020K-204A2 is mainly used to measure angles precisely. Its application is found in robotic research and robotics-driven tasks, such as object-oriented categorization and object-holding operations. In the automotive industry, it is used as a position sensor. It can detect the angular motion of the linkages connected to the steering column and the acceleration or deceleration of the car. This potentiometer is also capable of detecting differential wheel speed for traction and stability control of vehicles.In household appliances, the PTM902-020K-204A2 can be used to detect the angular displacement of a robotic arm for precise navigation. It is also capable of detecting the location of the tines within the grille section of a washing machine.In conclusion, the PTM902-020K-204A2 rotation sensor is a device that proves to be essential in many industries due to its rotational feedback. Since it is able to detect mechanical motion and convert it into electrical signals, it provides a great deal of accuracy and reliability in various systems. Therefore, it is a vital component and plays an essential role in the transitioning of mechanical motion into electrical signals.
