Generates A/B phase output signal with a resolution of 0.5 µm for feedback to an NC unit and up/down output signal for a display unit.
Selectable resolution and output pulse width
Compact design of 32 x 171 x 144 mm / 1.3"x 6.7"x 5.7" (W x H x D) permits the detector to be located in tight spaces as in a switchboard.
Operable from 5 V power supply. With the optional PU20 power supply unit, power for up to 3 axes can be supplied.
2-axis addition available with the analog addition unit MW10.
A/B phase signal, up/down signal, zero point signal and alarm signal output by differential line driver.
