Slide Potentiometers are resistive devices which measure the position of a sliding contact, in relation to a fixed contact resistance. This motion is usually of linear nature, however rotary technology exists too. This electrical construct is often overlooked in favor of more advanced solutions, however, combined with a simple mechanical action, it can be used to accomplish a variety of tasks.

The PS45M-0MC2AR5K is a single turn slide potentiometer that is 20mm in length. Its main features include a rated power of 0.05 Watts, an operating temperature ratio of -55°C to 105°C and a resistance value of 500Ω. The contact material is solid silver, and the maximum sliding force is 30 gram-force (gf).

Application Field

The PS45M-0MC2AR5K slide potentiometer is suitable for use in a variety of applications. It is mainly used in industrial, commercial, and automotive applications. Its rugged construction ensures it can withstand adverse conditions, such as high temperatures, high vibration, and dust. In addition, its long-term stability maximizes the life of the product. The slide potentiometer is ideal for applications such as position sensing, motor speed control, motor temperature control, volume control, and lighting control.

Working Principle

Slide potentiometers work by measuring the relative value of electrical resistance between two fixed points. This is done by using the resistance of the sliding element moving through a track of resistive material. As the slider is pushed or pulled from one side to the other, the resistance in between the two fixed points will change, providing the input that is required to calculate the slider\'s position.

The PS45M-0MC2AR5K has a single turn track resistance, which means the slider can only move around the resistance track once. This single turn track resistance is rated at 500Ω and has a maximum sliding force of 30grams. This means that the slider will move along the resistance track with no more than 30 grams of force. As the slider moves on the track, the resistance between the fixed points varies, providing the electronic signal that is necessary for the application involved.

The PS45M-0MC2AR5K also has a resistance value rate of 10%. This value increases as the slider is moved along the resistance track, providing a higher resolution for the signal. This rate indicates the accuracy of the device, and the 10% value provides a highly sensitive and reliable output.

In summary, the PS45M-0MC2AR5K works on the principle of a variable resistor that is moved by physical means. Its rated power is 0.05W and its operating temperature range is -55°C to 105°C. It has a resistance track rated at 500Ω with a change in resistance value rate of 10%. This slide potentiometer is suitable for various industrial, commercial, and automotive applications, and its rugged construction ensures it can withstand adverse conditions such as high temperatures, vibration, and dust.
