RM36 series non-contact rotary encoders - 1

The RM36 is a high-speed magnetic rotary encoder designed for use in harsh industrial environments. The non-contact two-part design removes the need for seals or bearings ensuring longterm reliability and simple installation. The encoder comprises a magnetic actuator and a separate encoder body. Rotation of the magnetic actuator is sensed by a custom encoder chip within the body, and processed to the required output. The encoder chip processes the signals received to provide resolutions to 13 bit (8,192 positions per revolution) with high operational speeds. Resolution options include binary and decimal. Output signals are provided in industry standard absolute, incremental or linear formats. The compact encoder body is 36 mm in diameter and provides dirt immunity up to IP68. The RM36 can be used in a wide range of applications including marine, medical, print, converting, industrial automation, metal working, motor control and instrumentation. Product range 5 V power supply version RM36I-incremental with 80 to 2,048 pulses per revolution (320 to 8,192 counts per revolution with x 4 evaluation) RM36S-synchro serial interface (SSI) with 320 to 8,192 positions per revolution 24 V power supply version RM36I-incremental with 80 to 2,048 pulses per revolution (320 to 8,192 counts per revolution with x 4 evaluation) RM36V-linear voltage output in a range of variants RM36C-linear current output in a range of variants • Excellent immunity to IP68 • Non-contact, frictionless design • High speed operation to 30,000 rpm • 36 mm diameter body • Accuracy ± 0.5° • Simple installation • Low inertia • Stainless steel body option • CE compliant, including RoHS - see Declaration of conformity

IMPORTANT: Power to RM36 encoders must be supplied from a DC SELV supply complying with the essential requirements of EN (IEC) 60950 or similar specification. The RM36 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.
