Features
Pin plunger and lever types available.
Drip-proof and flexible rod types are also available.
The pin plunger is sealed from the other switch mechanisms by a resilient rubber,
and the case and cover are sealed by adhesive so that the switch is resistant to
humidity, oil and dust. The degree of protection conforms to IEC IP63.

outlet directions. When placing your order for the
molded terminal type, add the following code to the
model number.

19…a = 19 mm with VCT
Standard leads are single-core vinyl cords (VSF) with a nominal cross sectional area of 1.25 mm2.
Standard vinyl cord lengths are 1 m, 3 m, and 5 m.
Mold thickness will be 19 mm when using VCT cords.
Standard unit has three lead outlets in the same direction.
Connect the black lead to the COM terminal, white lead to the NO terminal, and red lead to the NC terminal, respectively.

Precautions
■ MOUNTING
■ OPERATION
Use M4 mounting screws with plain washers or spring washers
to mount the switch. Tighten the screws at a torque of 12 to 15
kg-cm.
High sensitivity switch (Z-15H)
Solder the lead to the terminal by applying a soldering iron
rated at 60 W max. quickly (within 5 seconds). Note that
applying a soldering iron for too long a time or using one that is
rated at more than 60 W may degrade the switch
characteristics.
Panel mount type (Z-15■
■ Q)
When mounting a panel mount type switch (the one having a
suffix “-Q” in its model number) to a panel, tighten the hexagon
nut of the actuator at a torque of 50 kg-cm or less.
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 current of the relay
coil is the load of the switch.)
Do not apply a force of 2 kg or higher to the pin plunger.
Exercise care that the environment conditions such as
temperature and humidity do not change abruptly.
When mounting a panel mount type switch on its side, remove
the hexagon nut from the actuator and carefully adjust the dog
angle and operating speed because too large a dog angle or
too high an operating speed may damage the switch. Especially
be careful not to apply an impulsive force to the actuator when
operating it. By the same token, too high an operating speed
and too long an overtravel may damage a panel mount switch
with a roller pin plunger.
Drip-proof type (Z-■
■ 55)
Do not use mounting holes of the switch body when mounting
on panel with M12 mounting nut.
Flexible rod type (Z-15■
■ NJ■
■ 55) (drip-proof type)
The switch is not perfectly oil-tight; so, do not dip it in oil or
water.
Depending on the environments, the materials of the rubber
boots must be selected. Oil-tight, cold-resistive, and heatresistive rubbers are available from OMRON.
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.
