● 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 following operating range, if
inrush current occurs when the contact is opened or closed, it
may increase the contact wear and so decrease durability.
Therefore, insert a contact protection circuit where necessary.
The N-level reference value applies for the minimum
applicable load.This value indicates the malfunction reference
level for the reliability level of 60% ( λ 60 ). (JIS C5003)
The equation λ 60 =0.5×10 -6 /operations indicates that the
