Product Details
The GOS25C rotary encoder is a compact incremental encoder designed for automation and semi-automatic equipment installed in narrow spaces. With a 25 mm outer diameter and 4 mm solid shaft, it is a practical OEM replacement for the Japanese Omron E6A2 series in machinery that requires precise rotational feedback. It is used to convert shaft motion into pulse signals for speed, position, and direction control in processing machinery, packaging machinery, and other industrial automation systems. This model offers flexible resolution options up to 4096 pulses, 5V drive differential output, and reliable operation in anti-shock and dust-heavy environments, making it suitable for industrial users, electrical contractors, distributors, and OEM/ODM buyers seeking custom supply and wholesale sourcing.
