Mounting method
Mount the switch horizontally. After locking the mounting
plate in position, insert the switch body onto the mount
-
ing plate and fix it by tilting down the locking clasp of the
switch.
●
Screw fastening
Remove the knock-out holes of the mounting base,
and insert two (2) 4 mm dia. screws and fasten the
switch with two (2) 4 mm dia. nuts.

Handling Precautions
•
The recommended tightening torque is 0.5 N•m
max.
•
Verify that the amount of thread protruding
from the mounting face doesn’t exceed 13 mm.
Otherwise, the thread will interfere with the
locking clasp and could affect locking the switch
body into position.
•
Application of spring washer or adhesives is rec-
ommended to protect the switch from loosening
when used in high temperature environment.
●
Attachment using adhesives
Use an appropriate adhesive and glue the mounting base.
Handling Precautions
•
Apply a thin coating of the adhesive uniformly.
Too much adhesive will cause the detecting face
to float.
•
Make sure no adhesive seeps from the edges.
•
If any adhesive seeps from the switch body,
there may be difficulty mounting or removing
the switch. In addition, such a condition may
interfere with the detecting capabilities of the
device.

Handling Precautions
●
Precautions on installation and wiring
• Turn off the power supply before mounting or re
-
moving the switch.
• Never use this switch for applications being constant
-
ly exposed to a liquid.
• The presence of air bubbles on the sensing area of the
switch may result in unstable detection.
• If an extension of cord is necessary, use a 0.3 mm
2
(minimum) cable of a length of 100 m maximum.
• When using a commercially bought switching regu
-
lator, ground the flame ground terminal. Otherwise,
the switching noise may result in detection errors.
• Approximately 50 ms is required to reach to stable
operation after the power is turned on.
• Route the wires of the switch separately from
power lines or through an exclusive conduit.
Otherwise, an electrical surge may result in the mal
-
function of the switch or cause damage to the device.
• Errors may occur if any liquid is on the sensing face
or if the sensing face is scratched.
• If the cord is strongly pulled out by pulling around, etc.,
after mounting the switch body, it may be dislocated
from the mounting base. Make sure to check once again
if the switch is firmly attached after cord wiring.
●
Maintenance
• When the HPQ Series becomes dirty, wipe clean with
the soft and dried cloth.
• Mounting base and locking clasp are made of PVC.
Do not apply any organic solvents such as benzene,
acetone and thinner to avoid affecting the device’s
color change or to avoid any possible damage.
●
Disposal
• Absolutely don’t incinerate this product. It is made of
PFA and PVC substances that expel poisonous gases
when burnt.
• When the HPQ Series is to be scrapped, follow all
applicable local industrial waste codes.
