Proximity Sensors Technical Guide
Design
Sensing Object Material
The sensing distance varies greatly depending on the material of the
sensing object. Study the engineering data for the influence of
sensing object material and size and select a distance with sufficient
leeway.
In general, if the
Example: E2-X10D@
sensing object is a non- 14
magnetic metal (for
X t=1mm
example, aluminum),
12
d
the sensing distance
decreases.

Side length (one side) of sensing object: d (mm)
Size of Sensing Object
In general, if the object is smaller
than the standard sensing
object, the sensing distance
decreases.
Design the setup for an object
size that is the same or greater
than the standard sensing
object size from the graphs
showing the sensing object
size and sensing distance.
When the size of the standard
sensing object is the same or
less than the size of the
standard sensing object,
select a sensing distance with
sufficient leeway.

Thickness of Sensing Object
The thickness of ferrous metals
(iron, nickel, etc.) must be 1 mm
or greater.
For non-magnetic metal, a
sensing distance equivalent to a
magnetic body can be obtained
when the coating thickness is
0.01 mm or less. With pulse-
response models (e.g., E2V),
however, the characteristics may
vary. Be sure to check the
catalog information for the
relevant model.
When the coating is extremely
thin and is not conductive, such
as a vacuum deposited film,
detection is not possible.

Influence of Plating If the sensing object is plated, the sensing
distance will change (see the table below).

Mutual Interference
Mutual interference refers to a state where a Sensor is affected by
magnetism (or static capacitance) from an adjacent Sensor and the
output is unstable.
One means of avoiding interference when mounting Proximity
Sensors close together is to alternate Sensors with different
frequencies. The model tables indicate whether different
frequencies are available. Please refer to the tables.
When Proximity Sensors with the same frequency are mounted
together in a line or face-to-face, they must be separated by a
minimum distance. For details, refer to Mutual Interference in the
Safety Precautions for individual Sensors.
Power Reset Time
A Sensor is ready for detection within 100 ms after turning ON the
power. If the load and Sensor are connected to separate power
supplies, design the system so that the Sensor power turns ON first.
