Panasonic MA Motion Sensor Series - Manual (Page 11)

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, connect a capacitor
(minimum 33 µF) across its power input
terminals.
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 body. The sensor will
not detect objects consisting 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) 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.
7) To protect the inner circuit, wiring
should be max. 3 m
9.843 ft. .
4. Recommended installation
procedure
Install the photoelectric sensor so that it
is orientated correctly in relation to the
pass directions of the target objects as
shown in the figure below.
For the general precautions, refer to the
Notes for Motion Sensors on next page.
