Safety Precautions
Application Precautions
• Do not use the product in locations subject to explosive or
flammable gases.
• Do not use load currents exceeding the rated value.
• Be sure to wire each conductor correctly.
• Be sure to confirm correct operation after completing mounting and
adjustment.
• Do not drop or attempt to disassemble the product.
• Be sure to use the correct combination of switch and actuator.
• Use a power supply of the specified voltage. Do not use power
supplies with large ripples or power supplies that intermittently
generate incorrect voltages.
• Capacitors are consumable and require regular maintenance and
inspection.
Precautions for Safe Use
Mounting Direction of Switch and Actuator
The Sensor will not operate properly if the switch and actuator come
towards each other diagonally. The Sensor will, however, operate
properly if the switch and actuator come towards each other head-
on, horizontally or vertically (as long as the faces have the same
orientation).
Mutual Interference
If the switch and actuator are mounted in parallel, be sure to
separate them by at least 25 mm, as shown below.
Using for Hinged Doors
On hinged doors, install the Sensor at an opening edge as shown
below.
Solvents
Ensure that solvents, such as alcohol, thinner, trichloroethane, or
gasoline do not adhere to the product. Solvents may cause markings
to fade and components to deteriorate.
Installation Location
Do not install the product in the following locations. Doing so may
result in product failure or malfunction.
• Locations subject to direct sunlight
• Locations subject to humidity levels outside the range 35% to 85%
or subject to condensation due to extreme temperature changes
• Locations subject to corrosive or flammable gases
• Locations subject to shocks or vibration in excess of the product
ratings
• Locations subject to dust (including iron dust) or salts
Take appropiate and sufficient countermeasures when using the
product in the following locations.
• Locations subject to static electricity or other forms of noise
• Locations subject to possible exposure to radioactivity
• Locations subject to power supply lines
• It is advisable to mount the switches on non ferrous materials.
The presence of ferrous material can effect switching sensitivity.
Wiring
Perform wiring using wire with the following dimensions.
Stranded wire: 2.5 mm
2
Solid wire:
4.0 mm
2
Tighten the terminal screws with the specified torque. Not doing so
may result in malfunction or abnormal heat generation.
Terminal screw tightening torque: 1 Nm for NLPC and NSMC
0,8 Nm for NMPC
Be sure to turn OFF the power before performing wiring.
Do not touch charge parts (e.g., terminals) while power is
ON. Doing so may result in electric shock.
Do not allow the actuator to come close to the switch with
the door open. Doing so may cause machinery to start
operating and may result in injury.
Keep actuators (magnets) away from magnetically
sensitive equipment like PC harddisks, floppy disks etc.
The magnetic field of the magnet will damage existing
data.
Use guard stops in the way shown below to ensure that
the switch and actuator do not make contact when the
guard door is closed.
