RV28 28mm plastic shaft carbon potentiometer for welding machine

Description:

Carbon Potentiometer is an electronic component classified as variable resistor. Carbon Potentiometer is used as voltage divider to provide variable output voltage. Carbon Potentiometers uses carbon as resistive element. There are also different types of Potentiometers like Wire Wound type and ceramic type using different materials on resistive element. Carbon Potentiometer can be classified into logarithmic type and linear type depending on the mode of operations. Carbon Potentiometers are of many types and sizes depending on resistance value, power rating and type of mounting.

Mechanical specifications:

Total rotation angel	The angle is measured by rotating shaft from the end of terminal R1 to the end of terminal R3.	260°±10°
Rotation torque	Rotational torque when turn the shaft :without special provision,rotational speed is 60°/s in ambient temperature 5-35℃	2-20mN.m
Stop torque	The force that shaft transfer from terminal 1 to stop point or terminal 3 to stop point after 10 seconds until be break	≥5kgf.cm

Electrical specifications:

Total resistance	Measurement shall be made by the resistance between terminal R1and R3.	500Ω ~2MΩ
Resistance taper	Resistance changes	B
Total Resistance tolerance	Measurement shall be made by the resistance tolerance between terminal R1 and R3.	± 20%
Rated power	Rated power is based on continuous full load operation at the maximum voltage between terminal R1 and R3.	0.5W(50 ℃)
Residual resistance	Test residual resistance beteen terminal R1 and R2; terminal R2 and R3	R≤10KΩ R0≤20Ω 10KΩ<R≤100KΩ R0≤30Ω 100KΩ<R≤250KΩ R0≤50Ω R≥250KΩ R0≤0.1%
Rotation of noise	The murmur will appear when shaft turn from terminal 1 to terminal 3 by 30 rounds/minute equably speed.	≤47mV
Voltage proof	Input more then one minute voltage between terminals and shell.	2000VAC
Max. operation voltage	Maximal voltage which sustained by terminal R1 and R3	250VAC
Operating temperature	Potentiometer of the performance guarantee for the use ambient temperature	-30℃~70℃
Insulation resistance	Test voltage:DC 500V, Test position: Between terminal and case	200MΩ

Others:

Rotation life	After 10,000 rotation after the test, the changes impacted no more than ± (15% R +0.5 Ω) rotational noise of not more than 100 mv
Terminal strength	After welding (350℃, 3,5 seconds) after the of terminal contacts should be good, no termination loosening of
Soldering ability	Dip the terminals into tin tank at 235°C±5°C for 5±0.5 seconds, the soldering area should be more than 90%.
