The Model 755HS Encoder is ideal for applications requiring a small, high-precision, and high-performance encoder. Approximately 38.1mm in diameter and 38.1mm long, it will fit where many encoders cannot. All-metal construction and shielded ball bearings provide years of trouble-free use. A variety of blind hollow bore sizes are available with large bores allowing for shafts up to 14 mm. Attaching directly to a motor is quick and simple with the innovative flex mount, first developed by EPC. This industry standard mount eliminates couplings and increases reliability, while reducing overall length and cost. Where critical alignment is required, a Slotted Flex (SF) is available. A perfect replacement encoder where high reliability is required.
