20mm Size Metal Shaft Type RK203/EC20A Series 1. All the potentiometer types can be customized. Contact us with the detailed specifications if you have such requirements. 2. The same size of the non-switch type can be used as an encoder type. The switch type is an incremental encoder type only. Notes Heavy rotation torque and good operational feel, available in potentiometer and encoder type.
