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. 6 ●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 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 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, current 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.
