Features

Compact, reflective rotary Laserscale featuring high accuracy, high resolution, and high-speed response, Ideal for high-resolution angle measuring in HDD manufacturing equipment and precision measuring instruments

  • High resolution and high response speed(signal wavelength : 250nm)
  • Clock generator from 10 to 200 MHz
  • 907,200 pulses/Rotation (r=36mm)
  • Completely non-contact remote head
  • Available with reference point (BH200-RE) and without reference point (BH200-NE)

Specifications

Specifications
  • ※1 Reference point signal is asynchronous to CLK, 1/2CLK and 1/4CLK signals. Detection is unidirectional.
  • ※2 1/2 or 1/4 signals to CLK signal frequency. No output with input frequency of 50MHz or less. 1/2 CLK and 1/4 CLK signals cannot be used simultaneously with CLK signal.
  • ※3 Jitter of CLK signal: Pulse duration variation at 1000 pulses(3 p-p). Measured by inspection equipment at Magnescale Corporation.
