The HEIDENHAIN RON285C is a high-precision rotary encoder designed for demanding industrial automation applications. This sophisticated measuring device features 18,000 line counts and delivers exceptional accuracy with its 1Vpp output signal. The encoder operates with a 180 kHz cutoff frequency and includes an analog reference mark with coded positioning. Built with a rectangular flange featuring an 85mm centering collar and practical drainage channels, the aluminum housing provides IP64 protection against dust and water splashes. The hollow through-shaft design, with a 20mm diameter, allows for convenient axial clamping. Operating reliably in temperatures from 14°F to 158°F, this encoder connects via a 12-pin M23 male coupling. The unit comes complete with necessary mounting hardware and connection cables. Perfect for precise motion control and positioning applications, this German-engineered encoder delivers consistent performance and reliability. The device maintains optimal functionality in industrial environments while providing accurate measurement feedback for automated systems.
