Two-circuit Limit Switch
WL
Wide Selection of Two-circuit Limit
Switches
A wide selection of models are available, including
the overtravel models with greater OT, lamp-
equipped models for checking operation, low-tem-
perature and heat-resistant models, and micro-
load models.
Microload models are added to the product lineup.
Meets EN/IEC standards (only Switches with
ground terminals).
Switches with ground terminals have the CE
marking.

General-purpose Models
These Limit Switches are two-circuit double-break switches
housed in rugged diecast, thus making it an oil-tight, waterproof
and dustproof construction (complies with IP67).
In addition to the standard models, microload models are also
available.
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
resistant to water and most oils.
Set Position Marker Plate
After operation, set the indicator needle on the Head-mounting
marker plate so that is in the convex section of the Screws
bearing. For the WLD2, insert the needle so that is
is between the two main wires on the plunger.
Roller
The roller is made of self-lubricating sintered stain-
less steel and boasts high resistance to wear.
Requires maintenance (excessive overtravel)

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.
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.
Built-in Switch
Cover Setscrew
A Phillips screw is used to ensure ease of use.
The built-in switch (for all models except the micro-
Conduit Opening (See note 1.)
load models) has an extended mechanical life of 15
The conduit threads are parallel threads for G 1/2
million operations or more.
www.DataSheet4U.comtube and offer further increased sealing properties
when used in conjunction with the SC connector.
Note: 1. The display for conduit threads has changed from PF1/2 to G1/2, according to revisions of JIS B 0202. This is only a change in
the display, so the thread size and pitch have not changed. (Conduit threads Pg 13.5 and 1/2-14NPT are also available.)
2. By changing the orientation of the operational plunger, three operational directions can be selected electrically. (This is only pos-
sible with general-purpose roller lever, adjustable roller lever, and adjustable rod lever models. For the overtravel models, only
-2N Series models have this function.)
