2. If the switching speed is extremely fast, switching shock may
damage the Switch prematurely. If the switching frequency is too
high, the contacts may not be able to keep up with the speed.
The rated permissible switching speed and frequency indicate the
switching reliability of the Switch.
The life of a Switch is determined at the specified switching speed.
The life varies with the switching speed and frequency even when
they are within the permissible ranges. Always conduct appropriate
durability tests under actual conditions before using a Switch.
•
Make sure that the actuator travel does not exceed the permissible OT
position. The operating stroke must be set to 70% to 100% of the rated OT.
Models with Drip-proof Terminal Cover (Z-@A55-B5V)
Wiring
•
To attach the Protective Cover to the case, hold the cover in almost
parallel to the case and then push it to the case. If the cover is
pushed diagonally, the rubber packing may slip off, degrading the
sealability of the Switch.

Panel Mount Switch (Z-15@Q@, Z-01@Q@)
•
When mounting the panel mount plunger model with screws on a
side surface, be careful of the dog angle and operation speed.
Excessive dog angle or operation speed may damage the Switch.
•
When using the panel mount plunger model mounted with screws
on a side surface, be careful not to apply a large shock. Applying a
shock exceeding 1,000 m/s

may damage the Switch.
•
When using the panel mount plunger model mounted with screws
on a side surface, remove the hexagonal nuts from the actuator.

High-sensitivity Switch (Z-15H)/
Extra-high-sensitivity Switch (Z-15H2)
•
When using the Switch in a DC circuit, be sure to provide an arc
suppressor as well because the small contact gap of the Switch
may result in contact troubles.
•
In an application where a high repeat accuracy is required, limit the
current that flows through the Switch to within 0.1 A. Also, use a
relay to control a high-capacity load if the Switch is connected to
such a load. (In this case, the exciting current of the relay coil is the
load of the Switch.)
•
Do not apply a force of 19.6 N or higher to the pin plunger.
•
Exercise care that the environment conditions such as temperature
and humidity do not change abruptly.
•
Use round solderless terminals having the
4.3 dia.

terminals. Tighten the screws of terminals to

terminal shown below.
•
A cable 8.5 to 10.5 mm in diameter can be
applicable to the sealing rubber of the lead outlet of the Switch. A
two-core or three-core VCT cable having a cross-sectional area of
1.25 mm

is especially suitable for this.
•
Use M4 small screws with spring toothed washer are used as the
terminal screws.
Drip-proof Switch (Z-@55)
•
The Switch is not perfectly oil-tight; so do not dip it in oil or water.
•
The rubber boots are made from weather-resistive chloroprene
rubber.
•
Do not use Basic Switches in places with radical changes in
temperature.
•
Rubber boots and rubber caps will tend to harden at lower ambient
temperatures. If an Actuator is used in a pressed state for an
extended period of time at low temperatures, it may return slowly or
it may not return at all. OMRON can provide special Actuators for
use at low temperature with rubber boots or rubber caps made of
silicon rubber, which has superior resistance to cold. Ask your
OMRON representative for details.
Micro Load Applicable Range
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 here, 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%.

Split-contact Switch (Z-10F@Y)
The applicable current varies depending on how the contacts are
used. If the Switch is connected in series, the Switch can endure a
current 1.5 to 2 times higher than the current that can be applied in
parallel connection.
Flexible Rod Switch (Z-15@NJ@55, Drip-proof)
•
When the rod is fully swung, the Switch may operate when the lever
returns, causing chattering. Use a circuit that compensates for
chattering wherever possible.
•
Do not switch the rod to the fullest extent when the Switch is to
break a power circuit because such a practice may cause metal
deposition to occur between the mating contacts of the Switch.
