The PT15 carbon film potentiometer is a versatile and reliable component, featuring a 15mm diameter and a carbon element for precise resistance adjustments. Designed with a top adjustment mechanism, it allows for easy tuning, while its through hole mounting ensures secure and stable attachment to PCBs. The potentiometer offers a standard resistance range from 100Ω to 5MΩ with a tolerance of 20%, making it suitable for a wide variety of applications. With a power rating of 0.25 W at 50°C, it can handle moderate power requirements. The electrical rotation angle is 240° ± 20°, and the mechanical rotation angle is 265° ± 5°, providing smooth and accurate adjustments. Additionally, the PT15 operates efficiently in a temperature range from -25°C to +70°C, ensuring reliable performance in diverse environmental conditions.
The PT15 carbon film potentiometer offer control where frequent adjustment is required. The shaftless design allows for employment of different engagement mechanisms, such as a customized shaft, a motor control or a human interface adjustment. This potentiometer can also control variable outputs including frequency, change in motor speed or volume.
