MP Motion Sensor (AMN2, 3, 4)
MOTION SENSOR
(PASSIVE INFRARED TYPE)
Standard type
2. Dual lens colors (white and black)
are available
With an ultrasmall design and dual lens
colors (white and black), it is
inconspicuous, allowing the user to select
either white or black to match the
equipment color. This provides greater
flexibility in equipment design.
3. Both digital output and analog
output (with adjustable sensitivity) are
available.
4. Built-in amplifier for easy use
Has a built-in amplifier, and can be
connected directly to a microcomputer.

What is passive infrared type?
This sensor detects changes in infrared radiation which
occur when there is movement by a person (or object)
which is different in temperature from the surroundings.
Q As this sensor detects temperature differences, it is
well suited to detecting the motion of people by their
body temperature.

Slight motion detection type:
Detects movement of approximately
20cm 7.874inch.
6. Noise withstanding capability
Circuitry is contained in a TO5 metal
package, providing at least twice the
noise withstanding capability as
conventional type.

Min. 1 to 2m 3.281 to 6.562ft
Min. 1 to 2cm .394 to .787inch
7. A low current consumption type (46
µA) has also been added to the lineup.
A type that keeps current consumption to
46 µA (less than 30% compared to
predecessor) is now available.
Ideal for battery driven devices.

5. Detects even slight motion of a
person
With our sensor, even slight motions
made by people will be detected easily.
FEATURES
1. The world’s smallest* with a built-in
amplifier
Extremely compact. Ideal for use in
miniaturized devices.
• Fine motion detection capability within
approximately 2 meters of sensor.
Standard type:
Detects movement of approximately
30cm 11.811inch.
