Features & Benefits

With an IP66 rating for excellent resistance to coolant, oil and dust, the Mitutoyo LGK gage is ideal for integration into automation applications and harsh environments. Its compact size allows for installation into areas where space is limited. 

  • Photoelectric encoder gives the sensor high precision across the entire measuring range as well as higher resistance to electrical interference
  • Compact model offers the vibration/shock resistance of the proven LGF series at 1/5 the size
  • Excellent shock resistance: 100g/11ms (IEC 60068-2-27)
  • Linear ball bearing in spindle unit provides improved durability for at least 15 million cycles
  • Resolution of each model can be selected from 0.1μm (5 μin), 0.5μm (20 μin), or 1μm (50 μin)
  • Range: 10mm (.4”)
  • TTL output for ease of communication
