US Digital E4P OEM Miniature Optical Kit Encoder (Rotary)
The E4P miniature reflective encoder is designed to provide digital quadrature encoder feedback for high volume applications with limited space constraints. The E4P version utilizes an innovative, patented push-on code wheel which accepts shaft diameters of 2mm to .250".
The E4P reflective encoder is the leader for high quantity OEM applications, but the E4 is the ideal choice when a set-screw code wheel encoder is required.
The E4P miniature encoder base provides mounting holes for two #3-48, length 1/4" or two M2.5x.45mm, length 6mm screws on a .586" bolt circle. When mounting holes are not available, a pre-applied transfer adhesive (with peel-off backing) is available for "stick-on" mounting.
The encoder cover is easily snapped onto the base and is embossed with the connector pin-out.
The E4P reflective series encoder can be connected by using a (high retention 4-conductor snap-in polarized 1.25mm pitch) connector.
