Copal M Series, A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.
Copal potentiometers are used in various industrial equipment (industrial robots, injection molding machines, bank’s automatic teller machine), transportation equipment, computer peripheral devices, measuring instruments, and others for positioning and angle sensors, as well as for manual setting in communications equipment and measuring instruments.
Feature
- Line-up includes products ranging from 3 to 10 turns
- Cost-effective (M-22E10) in house comparison
- Dial can be attached (M-22 series only)
- RoHS compliant
