Rotary Potentiometers, Rheostats are typically composed of a resistive track with a slider or wiper that is used to vary the resistance between two points of the track. The 3590P-291-501L is a non-contact type Rotary Potentiometer and Rheostat consisting of a resistor element, rotor, and stator, all housed together within a watertight housing. Particulary suited for industrial and automation applications, this product\'s resistance model is modeled after a light dependent resistor aka LDR.

The 3590P-291-501L is designed for use as a multi turn or single turn trimmer, non-contact potentiometer. The resistance element is constructed of a low resistance carbon composition track. A carbon vanes mounted on a solid rotor provide torque control and physical contactless position sensing, allowing for precise position control. The unit is designed for fast and easy installation and removal without requiring tools.

The 3590P-291-501L works on the principle of light variation. As the rotor turns, light decreases in the clefts in between the rotor and stator, resulting in a decrease in resistance. Conversely, resistance increases as the rotor drives the light-sensitive vanes closer together, increasing the levels of light reaching the elements inside each cleft. This results in reduced resistance when the rotor is turning in the opposite direction. By utilising this effect of light variation, the 3590P-291-501L provides an accurate way to measure position and angle without the use of physical contact.

The 3590P-291-501L possesses various applications. It is primarily used for industrial automation, robotics, motor control, and any other application requiring precise position control with no mechanical contact. It is also used in the fields of hydraulic, pneumatic and optical systems as a sensing or control device.

The main advantages of the 3590P-291-501L are its high degree of accuracy and repeatability. It is less prone to dust and water contamination when compared with contact-type devices. The unit has an exceptional power range from 0.5W-3W, and its long life expectancy makes it suitable for long-term industrial applications. The unit can be used with any type of analog sensing such as analog-to-digital converters. The 3590P-291-501L is also RoHS compliant, making it environmentally responsible.

In conclusion, the 3590P-291-501L is a light dependent non-contact rotary potentiometer and rheostat, ideal for use in industrial and automation applications. It offers advantages such as high accuracy and repeatability, resistance to dust and water contamination, and a long lifespan. It is also RoHS compliant, making it an environmentally responsible choice.
