Measuring Standard: Glass scale-grating period: 0. 02mm Optical detecting system: Wavelength 880nm Resolution: 0. 005mm & 0. 001mm Length: 50mm--5000mm (5u), 50mm--1000mm (1u) Power supply: DC5V+-5% Output signals: TTL, EIA-422-A Double seals Design, 100% laser Calibration, The proven five bearings supporting design is used in the slide carrier of GS series transducer, The spring system was carefully designed using precise mathematical modeling to ensure highstabloloty of the slide carrier and offer more forgiving to transducer installation. The slide way of glass grating are lapped and JIS standard P5 grade bearings. The reliable Honeywell Alga As infrared LED and photo transistors are used in the optical measuring system.
