Solder Terminals PCB Terminals


●Degree of Protection

·Do not use the Switch under the environment where it is exposed to water.
The degree of protection is IP6X and the protection against water is not defined.
·Prevent the Switch from coming into contact with oil and chemicals. Otherwise, damage to or deterioration of Switch
materials may result.
·Do not use the Switch in areas where it is exposed to silicon adhesives, oil, or grease, otherwise faulty contact may result due to the generation of silicon oxide.
·The environment-resistant performance of the switch differs depending on operating loads, ambient atmospheres, and installation conditions, etc. Please perform an operating test of the switch in advance under actual usage conditions.

●Terminal Connection

·When soldering a lead wire to the terminal, first insert the lead wire conductor into the terminal hole and then perform soldering. Make sure that the capacity of the soldering iron is 30 W maximum and that the temperature of the soldering iron tip is approximately 300°C. (350°C maximum.) Complete the soldering within 3 s.
Using a switch with improper soldering may result in abnormal heating, possibly resulting in burn. Applying a soldering iron for more than 3 s or using one that is rated at more than 30 W may deteriorate the switch characteristics.
When using automatic soldering baths, we recommend soldering at 260 ± 5°C within 5 seconds. Make sure that the liquid surface of the solder does not flow over the edge of the board.

Crrect Use


· Turn OFF the power supply before mounting or removing the Switch, wiring, or performing maintenance or inspection. Fail-ure to do so may result in electric shock or burning.
·Use M2.3 mounting screws with plane washers or spring wash- ers to securely mount the Switch. Tighten the screws to a torque of 0.20 to 0.29 Nm {2.0 to 2.9 kgfcm}. Exceeding the specified torque may result in deterioration of the sealing or damage. Mount the Switch onto a flat surface. Mounting on an uneven surface may cause deformation of the Switch, resulting in faulty operation or damage.

●Operating Body

·Use an operating body with low frictional resistance and of a shape that will not interfere with the sealing rubber, otherwise
the plunger may be damaged or the sealing may deteriorate. With the pin plunger models, set the Switch so that the plunger can
be pushed in from directly above. Since the plunger is covered with a rubber cap, applying a force from lateral directions may cause damage to the plunger or reduction in the sealing capability.


·Do not handle the Switch in a way that may cause damage to the sealing rubber.
·When handling the Switch, ensure that uneven pressure or, as shown in the following diagram, pressure in a direction other than
the operating direction is not applied to the Actuator, otherwise the Actuator or Switch may be damaged, or durability may be decreased.

●Using Micro Loads

·Using a model for ordinary loads to open or close the contact of a micro load circuit may result in faulty contact. Use models that operate in the following range. However, even when using micro load models within the operating range shown below, if inrush current occurs when the contact is opened or closed, it may increase contact wear and so decrease durability. Therefore, insert a contact protection circuit where necessary.
The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% (λ 60). The equation, λ 60 = 0.5 × 10-6/operations indicates that the estimated malfunction rate is less than 1/ 2,000,000 operations with a reliability level of 60%.
