The Model 755HS is ideal for applications requiring a small, high precision, high performance encoder. Approximately 38.1 mm in diameter and 38.1 mm 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. Large bores allow for shafts up to 14 mm. Attaching directly to a motor is quick and simple with the innovative flex mount. This industry standard mount eliminates couplings and increases reliability, while reducing overall length and cost. Where critical alignment is required, a Slotted Flex Mount (SF) is available. A perfect replacement encoder where high reliability is required.
