General-purpose Models
These Limit Switches are two-circuit double-break switches housed
in rugged diecast, thus making it an oil-tight, waterproof and dust-
proof construction (complies with IP67).
In addition to the standard models, microload models are also avail-
able.
Nomenclature
A wide range of actuators with a range of functions are available;
rotating lever, plunger, flexible rod etc.
The rubber material in the standard models is designed to be resist-
ant to water and most oils.
Set Position Marker Plate
After operation, set the indicator needle on the
marker plate so that is in the convex section of the
bearing. For the WLD2, insert the needle so that is
is between the two main wires on the plunger.

Head
The Head used in the roller lever type, adjustable
rod lever type, or horizontal plunger type (except
the -2N Series) can be mounted in any of the four
directions by removing the screws at the four cor-
ners of the Head.
Shaft Section Seal
By fitting an O-ring to the rotary shaft and with an
appropriate interference of the screws, high-seal-
ing properties are maintained.
Bearing
The bearing smooths the plunger movement.
Built-in Switch
The built-in switch (for all models except the micro-
load models) has an extended mechanical life of 15
million operations or more.
Conduit Opening (See note 1.)
The conduit threads are parallel threads for G1/2
tube and offer further increased sealing properties
when used in conjunction with the SC connector.
Roller
The roller is made of self-lubricating sintered stain-
less steel and boasts high resistance to wear.
Lever
The lever forged of anti-corrosive aluminium alloy
features high corrosion resistances and outstand-
ing ruggedness. With roller lever, adjustable rod
and flexible rod models, the actuator position can
be set anywhere within 360_. (The lever cannot be
mounted in the opposite direction.)
Roller Lever Setscrew
Operational Plunger (See note 2.)
Cover Seal
By using an O-ring as the cover seal, an optimum
squeeze can be obtained and high sealing proper-
ties are assured as well.
Terminal Screws
M4 screws
Cover
Insulator
The insulator has outstanding insulation proper-
ties and prevents the generation of any gases
which may corrode the internal parts.
Cover Setscrew
A Phillips screw is used to ensure ease of use.
