Rotary Potentiometers, Rheostats and the 3310Y-011-502L

Potentiometers are variable resistors that are used to measure an electric voltage or current, usually in other electronic components such as amplifiers. They are usually made up of three terminals or contacts, two of which are used to measure the voltage while the third is typically used as a reference point. Rotary potentiometers, also known as shaft-type or spindle-type potentiometers, are perhaps the most common type available and typically feature a shaft that can be rotated to increase or decrease the resistance. Rheostats, on the other hand, are designed to be wired differently and instead of one reference terminal like a potentiometer, they have two and the resistance is adjusted by changing the current over the two terminals.

The 3310Y-011-502L rotary potentiometer is a commercially available component designed for use in a variety of applications. It has a basic construction consisting of a housing, a precision resistance element and a shaft that is rotated to adjust the resistance. The 3310Y-011-502L has a resistance range of up to 2k ohms with a tolerance of ±20%, meaning that the resistance can be adjusted between 1600 to 2400 ohms. The contact resistance is rated at 10m ohms while the rotational life is around 1000 cycles. The shaft type of this model is a standard 6mm spindle with a D-shaped knob.

The 3310Y-011-502L is primarily designed for applications that need precise adjustment of resistances for voltage or signal conditioning, such as impedance matching. It is a good choice for many electronic components due to its excellent tolerance and the fact that it can provide a wide range of resistances. Additionally, the 3310Y-011-502L can be used in applications that require precise control, such as trackball and remote control systems.

The 3310Y-011-502L works on the principle of a variable resistor. As the knob is rotated, a wiper arm attempts to maintain contact with the variable resistance element at all times. This movement across the element causes a change in the resistive value, which in turn results in a change of the voltage or signal at the terminals. The resistance can be adjusted with precision thanks to the inclusion of a precision mechanism that controls the contact between the wiper and the variable resistance element.

In conclusion, the 3310Y-011-502L rotary potentiometer is a compact and reliable commercial component that can be used in a variety of applications, from impedance matching to control systems. It features a wide range of resistance values and excellent tolerance, and works on the principle of a variable resistor in order to adjust the resistance with precision. As such, the 3310Y-011-502L is a great choice for any application that requires precise control.
