The MR316 ZapFREE heavy-duty fiber-optic rotary encoder from Micronor is designed for harsh environments and hazardous locations. Features include a passive and intrinsically safe design for use in all ATEX Type Group I/II hazardous locations, certified as "simple apparatus." The encoder has a standard size 90-mm encoder housing, large 12-mm shaft, and heavy-duty bearings and shaft seals (IP66). Remote encoder link up to 1000 m is possible. Together with the MR310 interface module, the fiber-optic encoder system offers a combination of incremental encoder, multiturn absolute position sensor, and tachometer.
