CAUTIONS WHEN USING
This product is mainly designed for use
indoors with general electronic devices.
If it is to be used outdoors, take suitable
precautions to protect it from water, dust,
dew condensation, and freezing.

control equipment for trains,
1. Operation environment
1) Shown below are ambient tempera-
ture, humidity and air pressure condi-
tions for operation, transportation, and
storage of the sensor.
ቢ Usable ambient temperature:
–20 to 55°C –4 to +131°F
ቢ Storage temperature:
–30 to 80°C –22 to +176°F
ባ Humidity: 15 to 85% R.H.
(with no freezing and condensation)
ቤ Air pressure: 86 to 106 kPa
Condensation may occur if the relay
is exposed to sudden temperature
change in a high-temperature, high-
humidity environment. This may
result in problems such as sensing
performance deterioration, non-
operation or insulation failure.
At temperature below 0°C 32°F, con-
densation and moisture may freeze
onto the sensor and cause problems
such as sensing performance
deterioration, non-operation or insula-
Motion-Detecting Sensor (AMP)
• Low-temperature, low-humidity
If the relay is exposed to a low-
temperature, low-humidity environ-
ment for an extended period of time,
the plastic components may become
brittle and fragile.
2) Be sure to use a stable power source
for the sensor. The sensor may operate
incorrectly if it receives voltage ripples of
more than 40 mV P-P.
3) Be sure to employ an absorber ele-
ment to prevent the internal circuit from
being destroyed if an external voltage
surge of more than 500 V occurs (mono-
polarized all-wave voltage of ±1.2×50
4) Static electricity or lightning may
cause the sensor to operate incorrectly.
5) Avoid using the sensor in the following
ቢ Locations exposed to direct sunlight
or other bright light sources.
ባ Locations where a heater lies within
the detection range.
ቤ Locations subject to direct air from an
ብ Locations with high humidity (e.g.,
ቦ Locations subject to sudden, extreme
ቧ LocaDtiaotnasSshuebejetc4tUto.csotrmong vibrations
ቨ Locations containing objects that
block infra-red rays such as glass.
ቩ Locations where blinds or curtains are
located near the detection range.
ቪ Locations near to a heat source or
ቫ Locations containing dust or corrosive
2. Detection characteristics
1) Since this sensor works by detecting
fluctuations in infrared rays, it will also
detect non-human heat sources (e.g.,
small animals, etc.) if they enter the
2) Since this sensor works by detecting
fluctuations in infra-red rays, it will not
detect a person that is motionless, even
if within the detection range.
3. Drop damage
If the sensor is dropped, damage can
occur resulting in incorrect operation. If
dropped, be sure to do a visual check of
the exterior for noticeable damage and
check the operation characteristics for
4. Other handling cautions
1) When installing the sensor, be sure
not to apply stress to the printed circuit
2) Be careful not to allow dust or dirt to
accumulate on the lens as this will adver-
sely affect the detection sensitivity.
3) When soldering the lead wire, perform
the operation within 3 seconds at 350°C
4) In order to avoid adverse effects from
noise, we recommend the use of
shielded wire when wiring.
5) In order to protect the internal cir-
cuitry, keep wire to a length of 1 m 3.3 ft
maximum from the sphere.
