WARNING
It indicates a hazardous situation which, if not
avoided, could result in death or serious injury.
NOTICE
It indicates a situation which, if not avoided, could
result in product damage as well as property damage.
WARNING
• This product is designed to detect the target object.
Do not use this product to protect human bodies or
a part of a human body.
• This product is not intended for use as an explosionproof
product. Do not use this product in hazardous locations
and/or potentially explosive atmospheres.
NOTICE
 Warming up
The circuit is not stable immediately after the power
turns ON, which sometimes causes the indicated
value to gradually fluctuate. Wait for about 5 minutes
after the power turns on before using.
 Handling of the sensor head
• This device is a precision machine. Do not drop, or
cause any other impact to this device. Doing so may
cause damage or malfunction.
• Do not apply weight greater than what is listed
below to the spindle. Do not apply rotational torque.
Otherwise the spindle may break.
• The spindle can rotate a maximum of 4.5°. When
using an offset contact (OP-77683) or similar, if
pressure in the rotational direction is applied to the
contact, the measurement position may change.
• When attaching and removing contacts, make sure
that the sensor head is detached from any metallic
plates, etc. Apply a tightening torque of 0.2 N•m or
less when attaching the contact.
• If dust, metal powder, or similar becomes attached
to the sliding part of the sensor head, mechanical
responses may become slow. If this happens,
replace the end of the sensor head with a
replacement dust seal (OP-87932). Refer to the
instruction manual included with the replacement
dust seal (OP-87932) for instructions on how to
replace the dust seal.
• Although the GT2-PA12K/PA12 has a protection
rating of IP67, avoid using it immersed in water or in
places where liquid such as oil may come into
contact with it.
