Thumbwheel Potentiometers

Thumbwheel potentiometers are customizable, knob-operated, multi-turn variable resistors that measure rotation angle and can produce analog linear or logarithmic output signals. They can also output digital codes representing angular position or fixed resistances. Thumbwheel potentiometers are a subtype of variable resistors and are usually placed in the environment where temperature or vibration cannot easily affect the performance.The 3352T-1-205LF is a thumbwheel potentiometer with an 8-pin single-in-line (SIL) package. It is a military single-turn, multi-position, electrically-variable potentiometer that uses a rugged mechanical device. It is designed to provide a variety of control tasks and utilizes a thumbwheel to provide control accuracy and ease of use. It consists of three terminal pins and the thumbwheel turn-counter with imprinted index control markings.The 3352T-1-205LF has a variety of application fields such as in temperature controllers, audio leveling controls, audio volume control, radio frequency amplifiers, light dimmer, industrial automation, and medical equipment. It is also suitable for applications in harsh environments where temperature or vibration cannot easily affect its performance. The working principle of the 3352T-1-205LF is based on two parameters: resistance and current. The resistance of the potentiometer is adjustable depending on the rotation of the thumbwheel. As the wheel is turned, the resistance between the resistor\'s ends changes, causing current to pass through a circuit. The current is measured by an analog-to-digital converter, which is then used to calculate the angular position of the wheel.The 3352T-1-205LF has a rotation angle within 12 turns and offers an adjustable resistance range from 0.250 Ohm to 50K Ohm. The resistance value is printed on the top of the package and varies depending on the application. The performance of the 3352T-1-205LF is measured at temperatures between -55°C to +125°C and a humidity range of 40% to 85%. It offers excellent linearity of 2%, signal strength of 2V drop and a resolution of 10%. Apart from its applications, the 3352T-1-205LF is also durable and reliable. It is manufactured from robust materials and has a cycle life of 50K under life life conditions. It offers a low power dissipation of 0.2 watts at 7.5V and 0.4 watts at 12V. The tolerance of the device is within 1% and the maximum input voltage rating is 25V.In conclusion, the 3352T-1-205LF thumbwheel potentiometer provides numerous features that make it suitable for demanding applications. It has a wide range of application fields including temperature controllers, audio and light controls, industrial automation and medical equipment. It has a rotation angle of 12 turns and adjustable resistance range of 0.250 Ohm to 50K Ohm. Moreover, it has a cycle life of 50K and excellent linearity of 2%. It is a reliable device that can be used in a variety of applications in harsh environments.
