Product Details
The GOS30C is a φ30mm incremental rotary encoder designed for accurate position and speed feedback in compact industrial automation systems. It converts shaft rotation into stable electrical pulse signals for motion control, counting, speed monitoring, and synchronized machine operation. This model is suitable for SMT machines, shoe machinery, automated assembly lines, and other equipment that requires reliable encoder performance in limited installation space.
Built for industrial users, commercial buyers, electrical contractors, and distributors, the GOS30C offers 4mm and 5mm shaft options, resolutions up to 4096 P/R, and multiple output types including open collector, complementary, and 5V line driver. It also supports A, AB, ABZ, and differential signal formats, with a default 0.7m cable and a durable anti-shock structure for long-term use. This makes it a practical choice for manufacturers, wholesalers, OEM/ODM projects, and buyers seeking customizable rotary encoder solutions.
