Rotary encoder : ENHP Series

Portable incremental type of Rotary encoder with handle

Portable incremental type of Rotary encoder with handle

Incremental manual handle type rotary encoders ENHP Series is designed for manual pulse input required applications such as Milling machines and NC lathe. Also, The Series implements various switch functions including emergency stop switch and realize superior portability in order to improve user’s convenience. In addition, ENHP Series newly adds Totem Pole output type for more diverse applications and working environments.
