Active inflared (area reflective) human detection sensor

Panasonic Corporation 

MA Motion Sensor (AMA1, AMB1, 2, 3)

NOTES

1. Environment

1) Avoid using the sensor in

environments containing excessive

amounts of steam, dust, corrosive gas, or

where organic solvents are present.

2) When the sensor is used in noisy

environments, implement a

countermeasure such as connecting a

capacitor (Min. 33 µF) across the power

input terminals. Only use the sensor after

verifying actual operation.

2. Wiring

1) Check all wiring before applying

power. Incorrect wiring may damage the

internal circuit (in particular, check that

the connection to the power supply is not

reversed.)

2) Avoid excessive removing and

replacing of the connector.

3. Detector surface (Optical surface)

1) Keep the detector surface clean.

Excessive dust or dirt on the detector

surface will deteriorate the sensing

performance.

2) Do not allow condensation or freezing

to occur on the surface of the sensor. If

condensation or freezing does occur at

low temperatures, the sensor may not

detect objects correctly.

3) This product is designed to detect the

existence of human bodies. The sensor

may not detect properly or the detection

distance may become unstable if the

objects consist of a low reflective material

(e.g., an object coated with black rubber,

etc.) or of a highly reflective material

(e.g., mirror, glass, coated paper, etc.).

4) The front surface of the lens and case

are made of polycarbonate resin and can

withstand water, alcohol, oils, salts and

weak acids. Other fluids such as

alkalines, aromatic hydrocarbons and

halogenated hydrocarbons may melt or

swell the lens and case, please do not

have such fluids touch the lens and case.

5) If you use the sensor with a cover or

filter connected to the front of the sensor,

the sensor may detect the cover itself, the

detection distance can change, and

unstable operation can result.

6) If this sensor is used in a position

where it will be facing another sensor,

light will be received from the other

sensor which can cause mutual

interference and malfunction. Therefore,

please verify the installation conditions

before use.

7) When multiple sensors are to be used

side by side, please verify that there will

be no mutual interference by installing

them with the proper spacing, depending

on the type as shown below.
