Rotary potentiometers and rheostats are electrical devices used to measure position, rate of change, and electrical current or voltage. The PDA241-SRT02-253B0 is a type of rotary potentiometer which provides position sensing and control for many applications. In this article, we will discuss the application field and the working principle of the PDA241-SRT02-253B0.

The PDA241-SRT02-253B0 is a single turn, 14 mm (0.55 inch) diameter rotary potentiometer with a conductive plastic element. It is suitable for volume control in audio and video equipment and can be used for motor position control, as well as for controlling the speed of motors or pumps. It is resistant to dust and water and has excellent durability, so it is suitable for industrial applications as well. Its resistance range is 10K Ohm to 100K Ohm.

The working principle of the PDA241-SRT02-253B0 is relatively simple. The device consists of a movable arm that is connected to a conductive plastic element. As the arm is turned by an external source, the element slides along a circular track, changing its resistance value. This resistance value is sensed by a semiconductor photosensor which in turn converts the resistance value into an electric signal. This signal can be used to control the speed or position of a motor, or to adjust the volume of an audio or video device.

In summary, the PDA241-SRT02-253B0 is a single turn rotary potentiometer which provides position sensing and control for many applications. Its resistance range is 10K Ohm to 100K Ohm and is suitable for volume control in audio and video equipment, motor control, and pump speed control. The working principle of the device involves a movable arm connected to a conductive plastic element which changes its resistance value as the arm is turned, resulting in a signal which can be used to control the speed or position of a motor or adjust the volume of audio or video equipment.
