Cautions in Using The Solenoids

In using the solenoid, there may be accidents of incompatibility that can not be thought on the desk, and from the aspect of reliability also please check the quality in actual use state.

  • General handling

    a)Please take care so as not to give a big shock to maintain initial characteristics.

    b)Please absolutely avoid using with voltage and current over the standard.

    c)When the rated range of use is regulated, please use within the standard.

    d)Please note the polarity of the coil (+ -) for those with polarity specification.

    e)Please avoid using the ambient temperature outside the standard.

  • Protection of contacts
    Sparks may occur at the contacts for control that operate the DC solenoid, causing wear of the contacts, noise disturbance, etc. Therefore, we recommend inserting a protection circuit suitable for each application.

    Circuit example

    Circuit example
  • Electric corrosion of the coil
    In a high temperature and high humidity atmosphere, when using the case to earth connection, depending on the connection method, it may be disconnected by electrolytic corrosion so please note the following points.

    a)Please ground the + side of the power supply.

    b)If the + side of the power supply can not be grounded, or if it is unavoidable to ground the - side of the power supply, switch on the + side of the power supply and set the coil to the - side.

    c)Please avoid ground the - side of the power supply and do not insert the switch on the - side.
