Features & Benefits

The Mitutoyo LGB linear gage is ideal for general measurements and its compact size allows for installation into areas where space is limited.  High precision ball bearings in the spindle guide provides extremely smooth movements and the low measuring force delivers accurate measurements on an array of materials.

  • Photoelectric encoder offers a high precision sensor across the entire measuring range, as well as, high resistance to electrical interference
  • Resolution: 1μm (50 μin)
  • L-shaped gage range: 5mm (.2”)
  • Low measuring force gage range: 10mm (.4”)
  • IP54 rating provides coolant, oil and dust resistance
  • Compact form (ø8mm straight stem) can easily be built-into gaging
  • TTL output for ease of communication
  • Air-lift model also available
