Table Displacement
Table Displacement due to Pitch Moment
Table displacement (arrow) when a load acts upon the section marked
with the arrow at the full stroke of the compact slide
Table Displacement due toYaw Moment
Table displacement (arrow) when a load acts upon the section marked
with the arrow at the full stroke of the compact slide
1. Selection of a bore size cannot be made only with above graphs.Select a bore size in accordance with “Model Selection” on page 5 to 6.
2. Displacement may increase after an impact load has been applied.When the table is subjected to an impact load, there may be permanent distortion
of the guide unit and increased displacement.

Selection Example
1. Selection conditions Mounting:Vertical
Max. speed: 500 mm/s
Overhang: 40 mm
Load weight: 0.1 kg
2. Selection conditions Mounting: Horizontal
Max. speed: 500 mm/s
Load eccentricity: 50 mm
Overhang: 30 mm
Load weight: 0.1 kg
Refer to Graph (3)based on vertical mounting and a speed of 500
mm/s.
In Graph (3), find the intersection of a 40 mm overhang and load
weight of 0.1 kg, which results in a determination of ø20.
Refer to Graph (10)based on horizontal mounting, a speed of 500
mm/s and load eccentricity of 50 mm.
In Graph (10), find the intersection of a 30 mm overhang and load
weight of 0.1 kg, which results in a determination of ø16.

Note 2) In the case of models with 5 and 10 strokes, the switch may not turn off due to operating range or two switches may turn on
simultaneously. Fix switches outside 1 to 4 mm further than the values in the above table. (if 1 switch is used, make sure
that it turns ON and OFF properly; if 2 switches are used, make sure that both switches turn ON.)

The auto switches above do not have a built-in contact protection circuit.
Therefore, please use a contact protection box with the switch for any of
the following cases:
 Where the operation load is an inductive load.
 Where the wiring length to load is greater than 5 m.
 Where the load voltage is 100 VAC.
The contact life may be shortened. (Due to permanent energising conditions.)

The indicator lights will illuminate
when both switches are turned ON.
(Solid state) (Reed switch)
When two switches are con-
nected in series, a load may
malfunction because the
load voltage will decrease
when in the ON state.
The indicator lights will illu-
minate if both of the switches
are in the ON state.
When two switches
are connected in par-
allel, a malfunction
may occur because
the load voltage will
increase when in the
OFF state.
Because there is no
current leakage, the
load voltage will not in-
crease when turned
OFF. However, depend-
ing on the number of
switches in the ON
state, the indicator lights
may sometimes dim or
not light because of the
dispersion and reduc-
tion of the current flow-
ing to the switches.
