Rotary Potentiometers, Rheostats

PDB241-GNL11-504A2 Rotary Potentiometers and Rheostats are used extensively in the sensing, control, and signal conditioning circuits in both Digital and Analogue systems. They are frequently used as position/angle sensors, voltage dividers and current controllers.

Application Field

The application field of the PDB241-GNL11-504A2 can be broadened within a wide range, such as appliances, communication equipment, medical devices, automotive, industrial controls and motion control systems. This rotary device has the capability to be specially designed and used in various application circuits with different functions.

Working Principle

The PDB241-GNL11-504A2 consist of three layers of overlapping tin-plated copper films. The contact element is created by a continuously varying resistance track that couples the two outer layers through the dielectric layer. The contact element contains an array of slotted intervals which control the contact area of the device.

When the adjustable element rotates, it creates a varying resistance between the two outer layers or ends of the sliding contact element. This varying resistance is similar to that of a rheostat. Also, by means of a 3rd layer acting as a terminal, a voltage divider is created, which is similar to a potentiometer.

The PDB241-GNL11-504A2 is commonly used with low-voltage and low power applications including the circuitry of instruments, adjustable outputs of amplifiers, sound transmission, dynamic signals, and sound level indicator circuits.

Advantages

The PDB241-GNL11-504A2 offers a few clear advantages over its counterparts including its small size, shape flexibility, variety of resistance value range and a range of output signal sensitivity and linearity. The similar resistance tracks between two layers make it possible to use this device in complex configurations with multiple galvanically isolated inputs which allows for flexibility in design.

The resistance range of the PDB241-GNL11-504A2 varies from 10K ohms to 10M ohms while its output signal is adjustable with the use of a single potentiometer. It can also be designed to produce a linear or non-linear output and its signal sensitivity is adjustable by adjusting the thickness of the resistive track.

Conclusion

In conclusion, the PDB241-GNL11-504A2 is a flexible and versatile rotary potentiometers and rheostats product. It is used in a wide range of applications due to its high accuracy, low power consumption, and a variety of resistance value ranges. Its 3-layer design and interchangeable elements make it perfect for complex applications with multiple galvanically isolated inputs and outputs.
