This feedback is compatible with Programmable Controllers, Numerical Controllers, Motion Controllers, and other positioning systems. The 845F provides code disk resolution up to 5000 pulses per revolution, frequency response of 210 kHz, and high immunity to electromagnetic interference. Housed in a rugged, size 25, NEMA Type 4 and 13, IP66 (IEC 529), aluminum enclosure, the 845F has a flange mount with integral coupling for ease of installation in harsh industrial environments.
