Detailed terminology for single potentiometer sensors

　　The unit of resistance of a single potentiometer is ohms, the unit symbol is Ω, in the circuit, the resistance is expressed by R, and the unit of resistance expressed by a single potentiometer is VR: milliohm (mΩ), Ohm (Ω), thousand ohm (kΩ), megohm (MΩ), gigohm, (G Ω) taohm (TΩ). The conversion between them is in thousands: 1MΩ=1000KΩ 1 KΩ= 1000Ω. Common units are: Ω, KΩ, MΩ, other milliohm. Gio. Taio are not commonly used

　　1, the name of the terminal: for the single potentiometer drive mechanism, the shaft is reversely adjusted to the end, the electrical terminal closest to the moving contact is called the 1 end; The terminal leading end of the other end is called the 3 end; The outgoing end of the touch point is called the 2-end.

　　2, grounding terminal: electrically connected to the shaft of the terminal plays a detailed role in shielding external noise.

　　3, rotating torque (starting torque) : the torque required to make a single potentiometer shaft (or knob) rotate.

　　4, temperature characteristics: resistance value with the characteristics of temperature change.

　　5. Terminal stop torque: the maximum torque when the rotating shaft (or knob) is turned to the terminal stop position without causing stop deformation and other visible damage.

　　6, positioning device: single potentiometer drive mechanism movement, feel positioning mechanical device.

　　7. Power reduction curve: The relationship between the maximum power consumption and the ambient temperature (expressed as a percentage of the rated power consumption).

　　8, nominal resistance value: mark the resistance value on the single potentiometer (standard resistance value).

　　9, cermet: the resistance body is printed on the ceramic substrate detailed description of the metal oxide by high temperature baking, with good weather resistance.

　　10, the highest operating voltage
