Proper Auto Switch Mounting Position for Stroke End Detection (ø6, ø8, ø10 common)

When Using Cylinders Adjacently

Auto Switch Mounting

• When detecting extended stroke end

• When detecting retracted stroke end

1. When cylinders with auto switches are adjacent to one another

as shown in the figure below, provide at least the amount of
space shown in the tables below between them.

If the space is not sufficient, the magnets in adjacent cylinders may

cause auto switches to malfunction.

∗

The space can be reduced by

attaching shielding plates (steel
plates 0.2 to 0.3mm thick) to the
sides of the cylinders facing each
other. In the case of bore size ø6,
be sure to attach a plate on
Cylinder A (on the surface opposite
to the switch groove).

2. In the case of bore size ø6 cylinders with auto switches,

keep the switch groove side surface at least 2.5mm away
from a magnetic substance.

If a magnetic substance is closer than 2.5mm, auto switches
may malfunction due to a drop in magnetic force.

∗

If this surface is to be used for mounting, a spacer composed of a non-

magnetic substance (aluminum, etc.) is required as shown in the figure
below.

Note 1) Solid state switch: D-F9

includes one auto switch.

Note 2) To prevent interference caused by the lead wire, provide a clearance of 10mm

or more in addition to the dimensions stated above. Negative numbers indicate
recess, positive numbers indicate protrusion.

• When tightening an auto switch mounting screw, use a watchmakers

screw driver with a handle of approximately 5 to 6mm in diameter.

• Use a tightening torque of approximately 0.10 to 0.20N
