Linear Gage LGF-Standard Dimensions, Robust Series 542

Series 542
Resolutions: 0.5μm, 1μm, 5μm

Features

Excellent vibration/shock resistance due to the design of the spindle guide section.
Sliding durability improved to remain serviceable for at least 15 million cycles (in house testing).
Shock resistance, 100g/11ms (IEC 60068-2-27)

*1: When the spindle speed exceeds 1500mm/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 inquire separately for the alarm signals. For the models using 50mm stroke gage, note over-speed 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.
