The Model GIS-MINI Series incremental encoder is ideal for applications requiring a small, high precision, high performance encoder. Approximately 25mm/30mm in diameter, it will fit where many encoders cannot. Designed with all-metal construction and shielded ball bearings, it will provide years of trouble-free use. The optional flange mounting is ideal for applications requiring a bolt-on, high precision encoder. With its high reliability and quick delivery, the Model GIS-MINI encoder is the perfect replacement encoder in this size category.
