Mitutoyo Linear Gages LGF, High Resolution, Robust Series 542
- LGF Linear Gauges are low cost electronic measuring probes, especially designed for very restricted measuring situations. Due to the advanced construction of the plunger guidance assembly the LGF is very resistant to external shocks and vibration.
- Outstanding protection against dust and splashing water for operation under severe conditions.
- Differential, square-wave signal for a wide range of applications. Excellent longevity due to linear ball bearings employed in the plunger unit.
- Wide range of application: due to its slim design the LGB can easily be integrated into measuring systems and automated machines.
- Long service life due to the linear ball bearing in the plunger assembly.

*1: When the spindle speed exceeds 400mm/s, an alarm signal will be output. Also, if using a Mitutoyo counter, an error message will be displayed. If using counters made by other companies, please consult your local Mitutoyo office. Note that over-speed error may occur depending on the impact amount when releasing the contact point freely.
*2: IP Code is a standard which classifies and rates the degree of protection provided against the intrusion of solid objects and water. This may not be applicable depending on the kind of liquid.
