Safety Precautions
Refer to Safety Precautions for All Limit Switches.
CAUTION
Antenna
<Shape and Extension>
Make sure that the antenna does not come into contact
with the human body, otherwise an electric shock may
be received.
If a metal plate is used as an antenna by connecting it to the built-in
or separated antenna of the NL, the surface area of the metal plate
must be 200 cm2 maximum. The antenna can be extended, provided
that the total length of the antenna is 1 m maximum and that the
bottom of the antenna is at least 10 cm away from the ground. Refer
to the illustrations below.

Braided Shield
• Non-grounded Object
• The shield is connected to the casing of the NL. Pay the utmost
attention so that the conductor connected to the antenna will not
come into contact with the shield. Secure the shield with insulation
tape.
If the sensing object is the following non-grounded conductor, the
NL will operate if the capacitance between the sensing object and
the ground is 100 pF or more. The larger the surface area of the
sensing object is, the higher its capacitance will be. The shorter the
distance between the sensing object and the ground is, the higher
the capacitance will be. Furthermore, the capacitance greatly
varies with the ground condition (e.g., dry sand, concrete, or wet

soil).
Contact with Non-grounded Conductor
The sensing object is equivalently grounded through capacitor C.

Installation
• The detection of conductors (e.g., iron, stainless steel, aluminum,
and brass objects) poses no particular problem. A conductor
coated with paint cannot be detected, however, because there is no
electrical continuity between the antenna and the conductor.
• Non-conductive objects (e.g., plastic, ceramic, glass, and cloth
objects) can be detected by grounding them indirectly.

If more than one NL is used in parallel or side-by-side, make sure that
the distance between the antennas is at least 4 cm.
• Do not disassemble the NL, otherwise the internal wiring will be

• Make sure that the conduit opening is free of foreign materials or
cuttings.

• The sealing of the NL uses nitrile butadiene rubber (NBR), which is
highly oil resistive. If exposed to some types of oil or chemical
indoors or outdoors, however, the NBR may deteriorate. Contact
your OMRON representative for details.
• Make sure that the load is connected according to the connection
diagram. The internal circuit of the NL will break due to mistakes in

• The blue (black) lead wire of the connection cable will be connected
to the casing internally if the model is the NL1 or NL2. The NL1 or
NL2 does not operate with the service power supply of the PC
(Programmable Controller) because the negative end of the service
power supply is not grounded. The noise immunity performance of
the PC will be degraded if the negative end of the service power
supply is grounded.

• Remove the warning label on the end of the connection cable
before wiring.
• Provided that single-phase 200 V is supplied to the NL3, if one
phase is grounded, the power supply will be short-circuited and a
machinery breakdown will result. Use an isolating transformer and
ground the secondary side of the transformer instead.
• To maintain operating reliability and durability, connect the blue

• Load Switching
The NL3 switches AC loads. The maximum switching load varies
with the ambient temperature as shown in the following graph of
load characteristic curves.
