Reference Gauge

• Excellent vibration/shock resistance due to the design of the spindle guide. • Sliding durability improved to remain serviceable for at least 15 million cycles (inhouse testing). • Shock resistance, 100 G/11 ms (IEC 60068-2-27) Linear Gauge ลิเนียร์เกจ

• The LGF-Z series, which is equipped with a reference point mark on the linear encoder (refer to page G-9), and includes a 0.1 µm resolution type (refer to page G-8) is also available.
