Magnescale MJ100/MJ110 Ribbon Type Scale (Digiruler)
Made in Japan
Manufacturer: Magnescale Co., Ltd.
Model: MJ100/MJ110
Features
- Capable of 40 to 1000 divisions
- Produces AB quadrature signals with a resolution from 2 μm to 125 μm, when used in combination with the optionally available
Use the DigirulerR PL25 head unit with the SL110/130 scale unit (signal wavelength: 5 mm), or the PL60 with the SL331 scale unit (signal wavelength: 2 mm). - Supply voltage 5 V input, Line driver (EIA-422 compliance) output
- Voltage 12 to 30 V input, Open collector (lOL=50 mA maximum) output
- MJ100 also generates U/ V/ W phase output with a period of reproduced DigirulerR signal (5 mm with PL25; 2 mm with PL60)
