Conductive plastic technology precision potentiometers

Our precision potentiometers use conductive plastic technology, are available as wirewound models with larger power dissipation and longer lifetime or use hybrid (combined advantages) technology. A wide choice of resistive outputs is offered. The contactless potentiometers (long lifetime) use Hall effect IC technology and offer DC voltage output.

Huiren Electronics standard rotary sensors

Compact and easy to design in, the potentiometer rotary position sensors provide you with a simple and cost-effective rotational sensing solution. They are ready to use and include the sensor, a back-biasing magnet and an advanced signal conditioning IC, all housed in a special multi-chip package. Besides the standard rotary sensors, we also offer you custom made solutions. Range in ohm between 1kΩ and 200kΩ. Temperature range from -40C up to 85C.

Precision Potentiometers

Our standard potentiometers are wire wound potentiometers with high accuracy (linearity up to ± 0,05 %), high reliability and a long rotational life.They are used in a wide range of industrial applications and in railway applications.Each potentiometer is supplied at the required ohmic value in the range of feasible values.Multiple-units potentiometers are achieved by combining several units.

Precision potentiometers standard requirements

Whether for standard requirements or as customised special orders - Huiren Electronics potentiometers stand out primarily due to continuous utmost precision. - From the world's smallest conductive plastic potentiometer to the contactless rotary sensor. We offer standard potentiometers and customized solutions in a plastic-, aluminum- or steel body (stainless). Variations in spindle geometry and -length, flexibility in electrical connections, robust brush- or ball bearings and a range of rotation angles make our precision potentiometers - a versatile solution for many industrial and automotive applications.

Potentiometer controls

You can potentially apply this system to an infinite variety of controls by connecting a spring potentiometer to different rotating components. For example, conventional steering wheel controllers work exactly the same way, with the wheel rotating the direct contact potentiometer arm directly. Some joysticks use an additional potentiometer for a Z-axis, activated by rotating the stick itself.

Potentiometers work status

Each spring return potentiometer is connected to one of the analog joystick potentiometer shafts so that pivoting the shaft rotates the contact arm. In other words, if you push the stick all the way forward, it will turn the potentiometer contact arm to one end of the track, and if you pull it back toward you, it will turn the contact arm the other way. Varying the resistance of the potentiometer alters the electrical current in the connected circuit. In this way, the potentiometer translates the stick's physical position into an electrical signal, which it passes on to the joystick port on the computer.

Conventional Analog: Potentiometers

Each analog joystick potentiometer consists of a resistor, in the form of a curved track, and a movable contact arm. The computer power supply conducts electricity to the input terminal, through the curved resistor, through the contact arm and back to the joystick port on the computer. By moving the contact arm along the track, you can increase or decrease the resistance acting on the current flowing through this circuit. If the contact arm is on the opposite end of the path from the input connection terminal, electricity will have to flow through a long length of resistor, so it will face maximum resistance. If the contact arm is near the input terminal, the potentiometers will have minimal resistance.
