In operating the feeler with a vacuum pump, use such an air-pass system as shown in Fig. 1 to enable air driving. The optimum vacuum rate is 0.04 to 0.067MPa. Further, put
such an orifice as shown in Fig. 2 on a tube from the air lifter connector to control the air suction and discharge speed. The feeler is lifted at the air discharge to the vacuum pump.

Direct connected to A/B quadrature counter
Reduced measurement error
Precision dual spindle support allows for a smooth spindle motion and virtually error free measurements.
Reduced measuring force
The measuring force can be reduced to a minimum of 0.3 N in three selectable steps using the measuring
balancer (option). The force is maintained constant regardless of spindle movement direction.
Soft spindle return. A braking mechanism reduces spindle return speed,
therby eliminating the danger of damaging either the surface plate or the workpiece.

DK Series measuring unit output signals
The signals output from this measuring unit are A/B quadrature signal, Z signal in the
form of voltage-differential line driver output compliant with EIA-422.
When connecting with MG40 series measuring system,
output signal have to change to the serial output
from A/B output by a switch on interpolation box.

The travel amount of the measuring unit is detected every 50 ns, and the phase
difference proportional to the amount traveled is output. The phase difference
changes in integer multiples of 50 ns. Also, the minimum phase difference for the
