Internal Circuits - Omron WLM Datasheet

Models/Ratings
Operating Maximum
characteristics rated voltage
LED 10 to Approx. 1 mA WL@-LD
115 VAC, DC
Note: 1. In the model number, @ indicates the actuator number. For
example, MCA2, etc.
2. The default setting is "light-ON when not operating." Turn the
lamp holder by 180 to change the setting to "light-ON when
operating."
Nomenclature
Release Plunger
Hardening method changed for greater abrasion resistance.
Standard Model Long-life Model
Sintered
alloy
Head
The Head can be mounted in any of the
four directions by removing the screws at
the four corners of the Head.
Shaft Section Seal
By fitting a double seal consisting of an oil seal
and an X-ring to the rotary shaft, even greater
sealing properties are achieved.
Standard Model Long-life Model
O-ring
Oil seal
Smoother Movement
A grease holder is provided on the shaft to
prevent the grease from running out.
Standard Model
Long-life Model
Grease holder
Smooth movement is achieved using
olefin grease. (Standard models use
molybdenum disulfide grease.)
Bearing
The bearing smooths the plunger movement.
Built-in Switch
Built-in switch with SPST-NO+NC contact form.
Note: By changing the direction of the operational plunger, any one of the three operational directions (both sides, left, or right) can be selected.
(Only applicable to the WLMGCA2-@.)

Contact spring
Set Position Marker Plate
The set position is easy to view. The stroke is
indicated in fluorescent color that is visible from
the slit in the rubber cap.
Roller
The roller is made of self-lubricating stainless sintered
and boasts high resistance to wear.
Conduit Opening
In addition to level screws which use G 1 / 2 tube, direct-
wired and pre-wired connectors have been added.

Lever
The lever forged of anti-corrosive aluminium alloy
features high corrosion resistance and outstanding
ruggedness. With roller lever models, the actuator
position can be set anywhere within 360°. (The lever
cannot be mounted in the opposite direction.)
Operational Plunger (See note.)
Cover Seal
By using a packing seal as the cover seal, an
optimum squeeze can be obtained and high sealing
properties are assured as well.
Terminal Screws
Four, M4 screws
Cover
Separator
The separator has outstanding insulation
properties and prevents the generation of any
gases which may corrode the internal parts.
Cover Mounting Screw
A Phillips screw is used to ensure ease of use.
