ER28C-P series are reflective optical encoders. These encoders are designed with two or three channels output, and
also with resolution from 500 pulse per revolution (PPR) to 20000 PPR. Because of the bear-less and split-type design, ER28C-P has very smaller size：28mm (Cylinder). The low profile design can save assembly space and system weight, and the bear-less structure can reduce some potential failure risks, such as motion wear and grease volatilization. ER28C-P series encoders can be widely used onto stepping motor ,DC motor and BLDC motor with 28mm frange size.
