Here's what each part of the name signifies:

RM-065: This is the model or series designation for the trimpot variable resistor, providing certain specifications or features.

1M OHM: This indicates the resistance value of the trimpot, which is 1 megohm (1,000,000 ohms). The unit of resistance is ohms.

Trimpot Variable Resistor: This describes the type of component. A trimpot is a type of potentiometer (variable resistor) that can be adjusted or trimmed for specific applications.

6mm: This refers to the size of the trimpot, typically indicating the diameter of the shaft or the physical size of the component.

PRINT CODE 105: This indicates the printed code used to represent the resistance value. In this case, "105" represents a resistance value of 1 megohm. The printed code helps in identifying the component's resistance value easily.
