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.

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.

Nomenclature

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.

Roller

The roller is made of self-lubricating sintered stain-

less steel and boasts high resistance to wear.

Requires maintenance (excessive overtravel)

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.

Conduit Opening (See note 1.)

tube and offer further increased sealing properties

when used in conjunction with the SC connector.

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.

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.

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.

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.)

Note:

1. The above figures are for standard currents.

2. Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).

3. Lamp load has an inrush current of 10 times the steady-state current.
