What is a Motion Sensor?
The motion sensor is an infrared
human detection sensor, which, as
opposed to factory automation sen-
sors that are used with factory
equipment, is designed to be incor-
porated into various devices that
exist around us in daily life.
Motion sensors are not for use in
factory automation.
Types of motion sensor
Motion sensors are divided into two types.
Passive infrared type
Designed to cover a wide area, this sensor detects
human presence. The sensor, rather than emitting light
such as from LEDs, detects the amount of change in
infrared rays that occurs when a person (object),
whose temperature is different from the surroundings,
moves.

1. As this sensor
detects temperature
differences, it is well
suited to detecting
the motion of people
by their body tem-
perature.
2. Wide sensing area.
3. Detection

be set.
Spot type
10m detection type
Standard type
Slight motion
detection type
Area reflective type
As the name implies this sensor emits infrared rays
from an LED. Using the reflection of those rays the
sensor measures the distance to the person (object)
and detects whether or not it is exists within a spe-
cific distance.
(1) Suitable for detection within specific ranges.
(2) Possible to select the detection distance.
• Selection possible in 1 cm increments between 5 cm and 10
cm.
• Selection possible in 10 cm increments between 20 cm and
200 cm.
Sensor
A compact distance-type sensor that is not easily
influenced by reflection ratio.
MA Motion Sensor
Short type
(5 cm to 10 cm)
Long type
(Horizontal
installation)
(30 cm to
200 cm)
Middle type
(20 cm to 80 cm)
Long type
(Vertical
installation)
(30 cm to
200 cm)
1.What is a Motion Sensor?
Application of MP Motion Sensor ‘
Automatically turn indoor lighting on and off
’
Method of use
Use as a human detection sensor to automatically
turn lights on when a person is present in a room
and to turn them off when nobody is there.
Points to consider when selecting
a sensor
1. The presence of a person must be detected
over a side area (room).
2. Even slight human motion must be detected.
MP Motion Sensor
Other application examples
Recommended conditions of use
1. Detection over a wide area (see note).
2. When the detection range extends to the wall or floor.
Note: If you wish to limit the range of detection, we recommended a spot type sensor.

Application of MA Motion Sensor
Running machine in athletic club
Sensing area
Sensor
Method of use
To prevent the runner from falling when he or she
tires and becomes unable to keep up with the
belt, the sensor slows the belt when the runner
falls back out of the detection area of the sensor.
Points to consider when selecting a sensor
1. The detection area must be limited so that only
the person using the running machine is
detected.
2. The detection distance must be limited.
MA Motion Sensor
Other application examples
Recommended conditions of use
1. Non-moving people (objects) and objects without a temperature difference are to be detected.
2. The detection distance and area must be limited (see note).
Note: With the aim of widening the detection range, the external trigger type, which prevents reciprocal interfer-
ence, is recommended when using multiple sensors.

Application example
Select a sensor that suits the objective.
Examples of automatic advertising and automatic verbal guidance
(ticket machines, vending machines, ATMs, illuminated photographs, etc.)
1.Advertising when a person walks
past the device.
2.When a person is close to
the device:
•The
device is turned on
•Instructions
for using the
machine are heard
Detection is necessary over a
wide area, therefore we recom-
mended the passive infrared type
‘
’ MP Motion Sensor.
The presence of a person in a very
limited range must be detected, there-
fore the detection area is small. We
recommend the area reflective type
MA Motion Sensor, which enables the
detection range to be select.
The current situation:
Techniques for reducing device power
consumption will increase dramatically.
To preserve the global environment
At the Kyoto conference for the prevention of global warming held in 1997, it was
agreed that “by 2008–2012, Japan will attempt to reduce the output of green-
house gases by 6% with respect to 1990 levels.”
Efforts in various fields to reduce greenhouse gases
Environmental action:
The beginning of “energy-saving” competition
Government
From the latter half of 1998 to the former half of 1999, the Ministry of International
Trade and Industry began enforcement of the Energy Saving Act, which requires
manufacturers to conserve energy.
The focal point of this act is the “Top Runner Method”, whereby “Excellent products” having the
highest energy efficiency are selected. This energy efficiency becomes a standard that other
products are required to meet within a certain period. Manufacturers unable to meet this stan-
dard are subject to punishment. A total of ten products are scheduled for implementation,
including automobiles and electrical appliances such as air conditioners, refrigerators, televi-
sions, VCRs, and personal computers.
Manufacturers
“Energy saving” is becoming an increasingly important factor in consumer selec-
tion of products. Manufacturers are therefore promoting their technical prowess
and aggressive stance with respect 10 environmental problems.
