Data sheet RLCD03_03 Issue 3, 18th September 2017 RLC2HD miniature PCB level incremental magnetic encoder sensor system RLC2HD 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). The information carrier is a periodically magnetised scale with a pole length of 2 mm. Radial or axial reading of the ring is possible. The RLC2HD is a moisture sensitive device. It should be soldered immediately after the transportation packaging has been opened. If not, baking procedure should be performed. State of the art position sensing assures highly repeatable position measurement under wide installation tolerances and temperature ranges. 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 × 12 mm ●● Incremental quadrature TTL output signals A, B, Z ●● Periodic, bidirectional index impulse ●● High speed operation ●● RoHS compliantsee Declaration of con

Storage and handling for linear magnetic scales > 60 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 * Use of alcohol for cleaning is considered safe, however, it is not allowed to immerse the scale in alcohol. For radial and axial ring storage and handling refer to magnetic ring data sheet. Dimensions Dimensions and tolerances are in mm. Sensing area Frame Sensing area

RLC2HD – Incremental, no line driver Power supply Power consumption Output signals Rise and fall time (cC = 50 pF) Timing diagram – Incremental, periodic reference mark Edge separation (µs) Resolution (µm) Reference mark Periodic reference mark, every 2 mm (as per scale pitch). The RLC2HD readhead should be ordered with reference mark option C. Magnetic scale or ring should be ordered with no reference mark. Position information is output in incremental quadrature format with periodic reference signals. Reference periods correspond to pole length of magnetisation.
