EFFECTS OF
SURROUNDING METALS
When mounting a proximity sensor flush
with a metallic panel, provide the
minimum distance shown. This prevents
the sensor from being affected by
metallic objects other than the target.

MUTUAL INTERFERENCE
To prevent mutual interference between
two sensors mounted opposite or parallel
to each other, be sure to space the two
sensors at a distance greater than that
shown here.

IMMUNITY AGAINST METAL
CHIPS
Even if aluminum or iron chips collect on
the sensing head, no signal is produced
indicating the detection of metal chips.
However, the detection signal may be
produced under either of the following two
conditions. If a signal is produced from
metal chips on the sensing head, remove
the chips from the sensing head.
Large Chips
If the size (d) of the chips collected on the
sensing head is greater than or equal to
2/3 of the size (D) of the sensing surface.

CONNECTION TO AC
POWER SOURCE
Be sure to connect the proximity sensor to
the power source through a load. Direct
connection may damage the sensor.
