■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.
