Mitutoyo Linear Gages LGF 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.
