Data sheet RE22D01_10 Issue 10, 12th September 2023 RE22 rotary magnetic shaft encoder The RE22 is a compact, high-speed rotary magnetic encoder designed for use in harsh environments. The traditional design allows for easy integration to existing machines. The RE22 can be used in a wide range of applications including marine, medical, print, converting, industrial automation, metal working and instrumentation. Product range RE22AC Analogue with a single sin e/cosine A magnet is mounted to the shaft within the encoder body. Rotation of cycle per revolution RE22BC this magnet is sensed by a custom Complementary analogue outputs encoder chip within the body, and with a single sine/cosine cycle per processed to give the required revolution output format. The encoder chip processes the signals received to provide resolutions of up to 13 bit (8,192 positions per revolution) with high operational speeds. Output signals are provided in industry standard absolute, incremental, analogue or linear formats. RE22DC BiSS C interface with up to 8,192 positions per revolution and optional revolution counter The compact encoder body is just 22 mm in diameter and provides dirt immunity up to IP53. RE22SC Synchro serial interface (SSI) with 320 to 8,192 positions per revolution RE22I C Incremental with 80 to 2,048 pulses per revolution (320 to 8,192 counts per revolution with x 4 evaluation) RE22Vx Linear voltage output in a range of variants ● High speed operation to 30,000 rpm ● Compact - 22 mm diameter body ● Absolute - to 13 bit (8,192 ppr) ● Industry standard absolute, incremental, analogue and linear output formats ● Accuracy to ±0.3° ● Simple

Storage and handling IMPORTANT: Power to RE22 encoders must be supplied from a DC SELV supply complying with the essential requirements of EN (IEC) 60950 or similar specification. The RE22 series encoders have been designed to the relevant EMC standards, but must be correctly integrated to achieve EMC compliance. In particular, attention to shielding arrangements is critical.
