*1. The NL3 has a capacitor and resistor for the protection of the built-in SCR. Therefore, the NL3 has leakage current.
*2. The NL3 requires a current of 30 mA for circuit protection.
        If the load current is less than 30 mA, connect the bleeder resistance R in parallel with the load as shown below so
        that the total current of the load circuit will be 30 to 300 mA.
        Obtain R from the following formula.

Make sure that the permissible power of the resistor is sufficient.

*3. Between current-carrying and non-current-carrying metal parts

Built-in Antenna Models

Coil Spring
NL1-C
NL2-C
NL3-C

*1. The coil spring antenna is movable in any direction. Make sure that the angle of the antenna is within 30° to the FP
       (free position) after the antenna comes into contact with the object.
*2. Use after removing the caution label.
Note: 1. The force that pushes the actuator must not exceed 1.96 N.
           2. The antenna is replaceable. Contact your OMRON representative for details.

Plunger
NL1-P
NL2-P
NL3-P

*1. The stainless-steel plunger antenna allows a maximum OT (overtravel) of 5 mm.
*2. This position is the FP (free position) of the plunger.
*3. Use after removing the caution label.
Note: Do not apply a force greater than 9.8 N to the plunger.

Separated Antenna Models

The dimensions provided for the NL1-SP, NL2-SP, NL1-SC, and NL2-SC are the external dimensions for the antennas. The casing dimensions of these models are all the same as those for the coil spring or plunger models.

No Antenna
NL1-S
NL2-S

*1. A standard 3-m high-frequency coaxial cable is provided.
*2. Use after removing the caution label.
Note: 1. Make sure that the shape of the antenna is suitable to the application.
              Use the plunger antenna or coil spring antenna as shown right for the NL1-S or NL2-S.
           2. Do not cut or extend the connecting cable.

Plunger Antenna
NL1-SP
NL2-SP

*1. The stainless-steel plunger antenna allows a maximum OT (overtravel) of 5 mm.
*2. This position is the FP (free position) of the plunger.
*3. A standard 3-m high-frequency coaxial cable is provided.
Note: 1. Do not apply a force greater than 9.8 N to the plunger.
           2. Do not cut or extend the connecting cable.

Coil Spring Antenna
NL1-SC
NL2-SC

*1. The coil spring antenna is movable in any direction. Make sure that the angle of the antenna is within 30° to the FP
       (free position) after the antenna comes into contact with the object.
*2. A standard 3-m high-frequency coaxial cable is provided.
Note: 1. Do not cut or extend the connecting cable.
           2. The antenna is replaceable. Contact your OMRON representative for details.

Note: Unless otherwise specified, a tolerance of ±0.4 mm applies to all dimensions.
