• Liquid- and dust-resistance conforms to IEC IP67 standard.
• Triple-sealed construction:
Plunger section sealed via nitrile rubber packing seal and dia-
phragm; switch section sealed via nitrile rubber cap; cable en-
trance sealed via encapsulating material.
• Standard cable (S-FLEX VCTF) in 2-, 3-, or 5-meter lengths of-
fers high flexibility with outstanding oil and extreme temperature
resistance.

Note 1: The model numbers for heads are of the form D4C-00@@,
with the numbers in the squares indicating the type of actua-
tor.
2: Actuators for plunger models, plastic rod models, and center
roller lever models cannot be ordered individually. They must
be ordered together with the head.
3: Consult your OMRON representative for details on cold-re-
sistant specifications.
Mounting Plates
The WL model incorporated by equipment can be replaced with the
D4C together with the Mounting Plate without changing the position
of the dog or cam.

Roller
The roller is made of self-lubricating sintered
stainless steel and boasts high resistance to
wear.
Lever
The lever forged of anti-corrosive aluminium
alloy features high corrosion resistances
and outstanding ruggedness.
Roller Lever Setscrew
This screw is made of stainless steel and has high
corrosion resistance.
Built-in Switch
Both standard load and microload models available.
Rotary Shaft
The shaft is made of stainless steel
decreasing the likelihood of rusting.
Diaphragm
The diaphragm is made of silicone rubber
and is resistant to temperature changes
and adverse weather conditions.
Cable
Vinyl cabtire cable and is resistant
to adverse weather conditions.
Head-mounting
Screw
Shaft Section Seal
By fitting an O-ring to the rotary shaft and with
an appropriate interference of the screws,
high-sealing properties are maintained. The
O-ring is made of silicone rubber and is resis-
tant to temperature changes and adverse
weather conditions.
