COMPONENT
The E4P is US Digital's OEM miniature optical kit encoder, 40% smaller than the S4T with higher resolution: 100-360 CPR (400-1,440 PPR in quadrature) with optional index channel on a single +5 V supply (4.5-5.5 V) at 21-29 mA no-load, -20 to +100°C operation; its modular base/code-wheel/cover design snaps onto motor shaft ends, making it the go-to low-cost feedback for robot drive wheels, small joint motors and education/service robots.
