The Model GIH-40 Series 40mm housing 6mm or 8mm hole is ideal for applications requiring a compact, high-precision, high-performance encoder. Approximately 40mm in diameter, available in two distinct formats – a blind hollow bore and a complete thru-bore. All-metal construction and shielded ball bearings provide years of trouble-free use. 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 (SF) mount is available.
