Linear Scales
Linear Scales ST36 SERIES 579 — High Accuracy Type
• Outputs 2-phase sinusoidal wave signals at 4 μm pitch. • The maximum effective measuring length is 3000 mm when the resolution is 0.01/0.02/0.05/0.1 μm (2-phase square- wave is output). • Compact detector head enables space saving design. • Along with the output specifications of 2-phase sinusoidal wave and 2-phase square-wave, the output specification of 1 Vp-p wave is also available. • Equipped with the function to display signal errors on the LED.
