Rotary Potentiometers and Rheostats are electrical devices that are used to adjust the voltage or electric current in a circuit. PTD902-2015F-B103 is a kind of Rotary Potentiometers and Rheostats which has a wide application field and working principle.

Application Field

PTD902-2015F-B103 is one kind of multi-turn Rotary Potentiometers which can be widely used as components in many kinds of instrument/equipment/machinery on different industial and commercial occasions such as automobile, motor, electric appliance, electronic appliance, measuring instrument, automation control system, industry robot, etc.

For example, in automobile industry, this kind of rotary potentiometers can be used to adjust the speed and the voltage of motor, and also can be used as components for signal control, location detection, and voltage regulating. In electronic appliance, PTD902-2015F-B103 can be used to adjust the capacity of capacitor, switch the signal, regulate the heat or detect humidity.

Working Principle

The working principle of PTD902-2015F-B103 as a kind of Rotary Potentiometers and Rheostats is based on the varying resistance principle. This device is made of a resistance element, a wiper and a rotating contact. When the rotary contact is turned, the length of the resistance element it contacts changes which leads to the change of the resistance value. The resistance value will become higher if the rotary contact moves in a clockwise direction, and vice versa.

The resistance value of the PTD902-2015F-B103 potentiometer ranges from 0 to 1K, and each turns of the rotary contact changes the resistance value for 20 units. Its withstand voltage is 5W ~ 9W while its working voltage is DC3V ~ DC24V. Furthermore, this potentiometer has 1pole 2wheels, 6 terminal pins and temperature range of -10°C ~ 55°C. Its insulation and penetration have also met the UL1053 standard.

With the help of PTD902-2015F-B103’s wide voltage range, very small rotational angle turn (20 units per turn of the rotary contact) and temperature range, engineers can use them in different instrument, equipment and machinery with high accuracy and broad temperature range.

Conclusion

The application field and working principle of PTD902-2015F-B103 has been discussed in this article. This kind of Rotary Potentiometers and Rheostats is widely used in automobile, motor, electric appliance, electronic appliance, measuring instrument, automation control system and industry robot. Compared to other rotary potentiometers, PTD902-2015F-B103 has wider voltage range, smaller rotary angle turn and wider temperature range. With all these features combined, it is a great choice for those need precise adjustment for respective instruments and equipment.
