Data sheet RLBD01_04 Issue 4, 18th September 2017 RLB miniature PCB level incremental magnetic encoder sensor system RLB is a PCB level incremental encoder sensor system consisting of a PCB sensor and a magnetic scale or a ring. It has been designed for embedded motion control applications as a position control loop feedback element in space constraint applications. Position information is output in incremental quadrature format with the option of a periodic reference mark (every pole). Maximum speed depends on the chosen resolution and minimum edge separation time; eg. for linear applications to 7 m/s at 1 µm and to 75 m/s at 10 μm. For more information about maximum speed in rotary applications go to magnetic ring data sheet. ●● Miniature design; 2 × 8 × 14 mm ●● Incremental quadrature TTL output signals A, B, Z ●● Periodic, bidirectional index impulse ●● High speed operation ●● Flex cable connection ●● RoHS compliantsee Declaration of conformity The information carrier is a periodically magnetised scale with a pole length of 2 mm. Radial or axial reading of the ring is possible. State of the art position sensing assures highly repeatable position measurement under wide installation tolerances and temperature

Storage and handling for linear magnetic scales > 75 mm > 75 mm WARNING: The MS magnetic scale should not be exposed to magnetic field densities higher than 50 mT on its surface. Magnetic fields higher than 50 mT can damage the scale. Motor oil Brake fluid Benzene Toluene For radial and axial ring storage and handling refer to magnetic ring data sheet. Dimensions Dimensions and tolerances are in mm. * Use of alcohol for cleaning is considered safe, however, it is not allowed to immerse the scale in al
