■Safety Precautions

●General Environmental Conditions

(1) 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 get 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 current when the Probe Pins are stationary after

they come into contact with the target at the

recommended 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

application.

●Voltage Application Conditions

(1) Apply voltage when the Probe Pins are stationary after

they come into contact with the target at the

recommended stroke position.

(2) Do not apply a voltage when the Probe Pins are not in

contact 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

instantaneous currents.

●Carrying Capacity

(1) The rated current that is given in the catalog is the maximum

continuous current for 1 minute for inspection of gold pads

under the conditions given on the left (general environment,

recommended stroke, current application, and voltage appli-

cation).

●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 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 for gold pads under the conditions given

on the left (general environment, recommended stroke, cur-

rent application, and voltage application).

(2) Depending on the operating environment and conditions,

the Probe Pins may need to be replaced sooner than the

specified limit in the datasheet due to increased resistance,

reduced

contact force, or other factors. Replace the Probe Pins as

required by the actual application.

●Contact Force

(1) If the current is increased, heat generated by the Probe Pins

will reduce the contact force.

●Recommended Mounting Dimensions

(1) The dimensions are reference values. Actual values will

depend on the material and thickness of the resin plate.

●Handling Precautions

Observe the following precautions when you are handling the

Probe Pins. Otherwise, the Probe Pins may be damaged.

• Do not apply excessive force to the contact sections of the

electroformed plungers.

• Do not apply excessive force to the coil spring section.
