The Model 755A Size 15 Accu-Coder™ is ideal for applications requiring a small, high-precision, high-performance encoder. Approximately 1.5" in diameter and 1.5" 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 0.750" (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.
