The Mitutoyo LG-100 linear gage is designed to be used inline or in measurement cells, enabling real-time measurement and data management in any type of work environment.

The compact, high-speed Mitutoyo LG-100 linear gage delivers production site visualization, improved productivity, and information feedback. The LG-100 has an IP67G rating for excellent coolant, oil and dust resistance, making it ideal for in-line measurements or use in measurement cells on the shop floor. Reference point signal output functions are featured throughout this series. When incorporating into a device the master setting value is easy to set and is retained after shutdown. The ability to recall the origin ensures excellent reliability. Up to 8 compact EJ counters counters can be linked providing the capacity to connect up to 16 gages.
