Slide Potentiometers are variable resistors used to measure motion in real-time applications. They are used extensively in industrial, medical and consumer control applications. The PDV20-21M-202B is a general-purpose, sliding potentiometer that is used for many applications, including linear motion measurement, position sensing, pressure measurement, rotation/angle measurement etc.

The PDV20-21M-202B is a dual potentiometer, meaning it can control two separate variables at once. It is constructed from two parts: a base and a potentiometer head. The base contains a linear track with a recessed groove. The head is a stationary contact block that slides along the track. It contains two metal strips which make contact with the grooves and act as a variable resistor. As the contact block moves along the track, the resistance between the two strips changes and this change is measured by the potentiometer.

The PDV20-21M-202B has a continuous resistance range of 1KΩ to 10KΩ. It can be used to measure linear displacement up to 2.5mm with a linearity accuracy of ±15%. It is also rated for temperatures ranging from −40°C to +85°C. The contact block is made from a durable polymer material while the track is made of nickel plated steel.

The PDV20-21M-202B has many advantages over mechanical linear motion sensors. First, it is maintenance-free and does not require repair or calibration. Additionally, it has very low power consumption and is highly accurate and repeatable. It is easy to install and requires no special tools. Finally, it is a cost-effective solution for many linear motion sensing requirements.

The PDV20-21M-202B is used in a variety of applications, ranging from robotics and medical equipment to automotive and industrial automation. It is often used in robotics to measure linear displacement, such as in robotic arms or legs. In medical equipment, it is used to measure human vascular pressure. In automotive applications, it is used to measure acceleration or speed. In industrial automation, it is used to detect position, torque and pressure in machinery and other machines.

The PDV20-21M-202B is an ideal choice for a variety of linear motion sensing needs. With its low power consumption, easy installation and high accuracy, it is a cost-effective choice for many applications.
