DATA SHEET RDD01_01 Issue 01, 28th September 2023 OnAxis™ Redundant Incremental Encoders The RM44 and RMF44 redundant are non-contact magnetic encoders with two independent outputs and no common connections between two devices. Redundancy is implemented only on the sensor and driver side. The encoders are suitable for demanding applications that require a higher level of safety. EASY INSTALLATION Redundancy for safety apllications Dual outputs inside one encoder 5 V power supply versions Excellent degree of protection up to IP68 High speed INDUSTRIAL AUTOMATION MOTOR CONTROL

General information The encoder consists of a diametrically polarised magnet and a separate sensor body (RM) or a sensor on a flange (RMF). The redundancy is realized in the sensor and driver side only. The encoder uses only one magnet (Ø7 x 4 mm). Designed for direct integration into high-volume OEM applications, the RM/RMF44 encoders can be used in a wide range of applications, including motor control and industrial automation.

Storage and handling Operating and storage temperature RMF44: –40 °C to +105 °C (limited by connector) –40 °C to +125 °C (soldering pads) The RM44/RMF44 encoders must be powered from a DC SELV supply that meets the basic requirements of EN (IEC) 60950 or similar specification. Packed individually in antistatic bags. Less than 20 products are packed individually in an antistatic box. If more than 20 systems are ordered, the parts are packed in antistatic plastic trays. Magnets and readheads are pack
