Trimmer Potentiometers

Trimmer Potentiometers, or trimmers, are variable resistors used to make fine adjustments or provide a variable voltage divider for analog circuits. They are connected in series with a voltage source and measure a fractional proportion of that voltage. They are used to calibrate, tune and adjust circuit parameters, such as gain and offset.A trimmer comes in many shapes and sizes, depending on the application. The CB10LH223M is an example of a trimmer potentiometer, designed specifically for the automotive industry. It has a high-accuracy rating of ±6%, with a temperature range of -40°C to 150°C. It features a wide-angle shaft with a three-point mounting with a set screw for further adjustment. It also features a corrosion-resistant body and a locking mechanism to prevent accidental adjustment.The CB10LH223M is a true three-terminal device, with the third terminal connected to the wiper pin of the potentiometer. This provides an exact output of the current voltage level of the potentiometer, instead of the approximate value that can be determined using a two-terminal device. This allows for more precise adjustment and faster calibration in the automotive industry.The CB10LH223M works on the principle of variable resistance. When the knob of the unit is turned, the resistance value changes. This value is determined by the three components that are connected to the potentiometer: the wiper terminal, the track terminals, and the third terminal.When the knob of the unit is turned, the wiper terminal moves across the track terminals. The resistance between the wiper terminal and the track terminals changes, while the resistance between the track terminals remains constant. This allows for a wide range of resistance values to be achievable.The third terminal of the potentiometer is connected to a current source, and the current flows through this terminal into the wiper. This current is proportional to the voltage difference between the wiper terminal and the track terminals. Thus, when the knob of the unit is turned, the current passing through the wiper changes, and the voltage potential at the wiper is proportional to this current. This voltage potential is reported at the third terminal, and this is what’s used to measure the voltage output of the unit.By providing an exact current output of the unit, the CB10LH223M provides a more precise adjustment of parameters and faster calibration in the automotive industry. The wide-angle shaft and three-point mounting with a set screw allow for further adjustment, and the corrosion-resistant body and locking mechanism keeps the unit secure from accidental changes. This makes the device an ideal choice for the automotive industry.
