Micro Load Models
Contact failure may occur is a General-purpose Switch is used to
switch a microload circuit. Use Switches within the areas shown in the
following chart. Even when using Microload Switches within the area
shown below, contact wear will become more extreme with loads that
generate surge current when switching and durability will be
adversely affected. If necessary, insert a contact protective circuit.
Microloads are indicated by N standard reference values. This value
represents the failure rate at a 60% (λ60) reliability level. (JIS C5003)
The equation λ60 = 0.5 × 10
of 1/2,000,000 operations can be expected at a reliability level of 60%.
Mounting
Appropriate Tightening Torque
A loose screw may result in a malfunction. Be sure to tighten each
screw to the proper tightening torque as shown below.
Operation
With the ZC-Q22(21)55, an
appropriate OT line is marked on
the plunger. Set the OT so that it is
between the two X-surface lines.
