Electroformed Probe Pins
XP3A
Electroplated Probe Pins for High
Reliability
• The Probe Pin that is made of only one part.
• The flat structure helps you reduce the pin pitch in comparison
with standard probe pins.
• Separating the spring and relay achieves a stable resistance and
greater durability.
■Feature
●Achieve the functions of four parts with one part.
●Separating the spring and relay achieves a stable
resistance and greater durability.
●The electroformed Probe Pins use a flat structure.
This allows you to position the pins at any angle.
In comparison with round pins, these flat Probe Pins help you
reduce the pin pitch.

■Safety Precautions
●General Environmental Conditions
(1) Use the Probe Pins at an ambient operating temperature of
–25 to 85ºC and a humidity of 30%.
(2) Use the Probe Pins in an ambient atmosphere that does not
contain dust, dirt, corrosive gas, or oil so that the Probe Pins
do not become contaminated.
●Stroke Conditions
(1) Apply a load to the Probe Pins only in the axial direction.
Never apply a lateral load.
(2) The life of the Probe Pins will be drastically reduced if the
recommended stroke is exceeded.
●Current Application Conditions
(1) Apply a current when the Probe Pins are stationary after
they have come into contact with the target at the recom-
mended stroke position.
(2) If a current is applied during the stroke, at a position other
than the recommended stroke, or when the Probe Pins are
not in contact with the target, the life of the Probe Pins will
be drastically reduced.
(3) The catalog value of the carrying capacity may not be met
due to Probe Pin deterioration or other factors.
Allow sufficient leeway when you design the actual applica-
tion.
●Voltage Application Conditions
(1) Apply a voltage when the Probe Pins are stationary after
they have come into contact with the target at the recom-
mended stroke position.
(2) Do not apply a voltage when the Probe Pins are not in con-
tact with the target. The Probe Pins will be damaged due to
discharge immediately before they come into contact.
(3) When a high voltage is applied to the contact probe, strictly
observe the current and voltage application conditions. Also,
take measures to prevent discharge or other large instanta-
neous currents.
●Carrying Capacity
(1) The rated current that is given in the catalog is the maximum
continuous current for 1 minute under the above conditions
(general environment, stroke, current application, and volt-
age application).
●Resistance
(1) If a large current is applied, the resistance may increase due
to deterioration of the contacts and internal components.
(2) As the number of strokes increases, the resistance may
increase due to deterioration of the contacts and internal
components.
●Durability
(1) The durability specification that is given in the catalog is a
guideline for the number of times that the Probe Pins can be
used without problems at 10 mA under the above conditions
(general environment, stroke, current application, and volt-
age application).
(2) Depending on the operating environment and conditions,
the Probe Pins may need to be replaced sooner than given
in the specifications due to increased resistance, reduced
contact force, or other factors. Replace the Probe Pins as
required by the actual application.
●Contact Force
(1) The contact force of the Probe Pins will be reduced at a tem-
perature of 85ºC or higher.
(2) If the current is increased, heat generated by the Probe Pins
will reduce the contact force.
●Recommended Mounting Hold Dimensions
(1) The dimensions are reference values. Actual values will
depend on the material and thickness of the resin plate.
