Incremental rotary encoder LM13 series

magnetic13-bitnon-contact

The LM13 is a contactless high-speed linear magnetic system designed for linear or rotary motion sensing in harsh environments. The system consists of a compact readhead and a separate selfadhesive magnetic scale or ring. Features Resolutions from 1,280 to 327,680 counts per revolution High speed operation to 20,000 revolutions per minute Integral set-up LED Benefits Compact readhead Excellent dirt immunity High reliability from proven non-contact sensing technology Industry standard digital and analogue outputs Product data Accuracy ±10 µm Accuracy grade for MS scales ±10 µm (available for lengths up to 20 m only), ±20 µm and ±40 µm Repeatability Better than unit of resolution for movement in the same direction Hysteresis < 4 µm up to 0.5 mm ride height Alarm High impedance on output lines A, B, A-, B-, Special option 02: Alarm is not signalled by high impedance state, Special option 07: Alarm signal is output parallel as line driver signal Linear expansion coefficient for MS scale ~ 17 × 10-6/K Pole length 2 mm Max. interpolation factor 8,192 Maximum length for MS scale 100 m Electrical Supply voltage 4.7 V to 7 V Set-up time 10 ms (first data ready after switch-on) Current consumption < 50 mA Connection 15 pin D type plug, 15 pin HD type plug, 9 pin CPC connector, 9 pin D type plug Mechanical Cable PUR high flexible cable, drag-chain compatible, double-shielded Mass Magnetic scale (1 m) 60 g, Cover foil (1 m) 3.5 g, Readhead (1 m cable, no connector) 80 g, Cable (1 m) 34 g
