5. Measuring unit output signals
h
e signals output from the measuring unit are AB quadrature signals, reference point
output signals in the form of di
f erential line driver output compliant with EIA-422.
Signal A
Signal B
Reference point
output
h
e reference point is the synchronized reference point that is at Hi level when the signal
A and signal B are at the Hi level.
Output signals at maximum response speed (at approx. 80 m/min)
200 ns (5 MHz)
Signal A
Signal B
50 ns
h
is measuring unit outputs AB quadrature signal with a maximum frequency of 5 MHz and
minimum phase dif erence of 50 ns. Use a counter or controller that can process these signals.

h
e minimum phase dif erence can be modii ed under special specii cations. (See “5-1.
Output signal phase dif erence”)
5-1. Output Signal Phase Dif erence
h
e travel length of the measuring unit is detected every 50 ns, and the phase dif erence
proportional to the length traveled is output. h
e phase dif erence changes in integer
multiples of 50 ns.
Also, the minimum phase dif erence for the signal A and signal B is 50 ns.
Signal A
Signal B
Integer multiples of 50 ns
