ø22mm XW Series Emergency Stop Switches
Operating Instructions
Removing the Contact Block
First unlock the operator button. Grab the bayonet ring ➀
and pull back the bayonet ring until the latch pin clicks ➁,
then turn the contact block counterclockwise and pull out ➂.

Notes for removing the contact block
1.When the contact block is removed, the monitor contact
(NO contact) is closed.
2.While removing the contact block, do not exert excessive
force, otherwise the switch may be damaged.
3.An LED lamp is built into the contact block for illuminated
pushbuttons. When removing the contact block, pull the
contact block straight to prevent damage to the LED lamp.
If excessive force is exerted, the LED lamp may be dam-
aged and fail to light.
Panel Mounting
Remove the locking ring from the operator and check that
the rubber gasket is in place. Insert the operator from panel
front into the panel hole. Face the side without thread on the
operator with TOP marking upward, and tighten the locking
ring using ring wrench MW9Z-T1 to a torque of 2.0 N·m
maximum.

Notes for Panel Mounting
To prevent the XW emergency stop switch from rotating
when resetting from the latched position, use of an anti-rota-
tion ring (HW9Z-RL) or a nameplate is recommended.
Installing the Contact Block
First unlock the operator button. Align the small ▼ marking
on the edge of the operator with the small ▲ marking on the
yellow bayonet ring. Hold the contact block, not the bayonet
ring. Press the contact block onto the operator and turn the
contact block clockwise until the bayonet ring clicks.
Notes for installing the contact block
Make sure that the bayonet ring is in the locked position. Check
that the two projections on the bayonet ring are securely in
place.
Wiring
1. The applicable wire size is 1.25 mm
2
maximum.
2. Solder the terminals using a 20W soldering iron within 5 sec-
onds, or at 260°C within 3 seconds. Do not apply external
force. Make sure that the soldering iron touches the termi-
nals only. When wiring, do not apply tensile force on the ter-
minals.
3. Use a non-corrosive rosin flux.
4. Because the terminal spacing is narrow, use protective tubes
or heat shrinkable tubes to avoid burning of wire coating or
short circuit.

PC Board Terminal Type
1. When mounting a contact block on a PC board, provide suffi-
cient rotating space for the PC board when installing and
removing the contact block.
2. When mounting an XW emergency stop switch on a PC
board, make sure that the operator is securely installed.

About PC Board and Circuit Design
1. Use PC boards made of glass epoxy copper-clad laminated
sheets of 1.6 mm in thickness, with double-sided through
hole.
2. PC boards and circuits must withstand rated voltage and cur-
rent, including the instantaneous current and voltage at
switching.
3. The minimum applicable load is 5V AC/DC, 1 mA. This value
may vary according to the operating environment and load.
4. Within the 2.8∗ mm areas shown in the figure below, termi-
nals touch the PC board, resulting in possible short circuit on
the printed circuit. When designing a PC board pattern, take
this possibility into consideration.

Screw Terminal Type
1. Wire thickness: 0.75 to 1.25 mm
2
(AWG18 to 16)
• Be sure to install an insulating tube on the crimping terminal.
2. Tighten the M3 terminal screw to a tightening torque of 0.6 to
1.0 N·m.
