• A load must be used when power is applied to the switch.
• A combination of short circuit and wrong wiring will cause per-
manent damage, regardless of short-circuit protection.

Mutual Interference
Erroneous operation due to mutual interference is caused when
switches are installed in parallel or facing each other.
Separate the switches by at least the distance specified in the table
below.
A (mm) B (mm)
FL7M-1P5_6_ 15 20
FL7M-2_6_ 20 30
FL7M-5_6_ 35 50
FL7M-10_6_ 70 100
Influence from Nearby Metal Objects
If a metal object other than the work piece is located nearby, this
switch’s sensing distance characteristics will change.
Keep the minimum distances between the switch and metal objects
shown in the table below.
A (mm) B (mm)

A : Distance from the sensing surface of the proximity switch to an
iron plate in front of the switch.
B : Distance from the axis of the proximity switch to an iron plate in
front of the switch.
Tightening Torque
zWhen a nut is used
e permissible torque is dierent depending upon the distance
from the top of the switch head. Tighten the body at less than the
maximum permissible torque shown below, and always with the
enclosed nuts and washers.
e tightening torque varies depending on the mounting plate or
housing, the nut and washer material, and the condition of the
mounting surface. Check that the torque is suitable for the actual
combination of items before use.

Handling Precautions
• Do not tighten the body by applying torque to the indicator
unit (plastic unit).
• Do not mount the body using a set screw. Doing so might
damage the switch.
AND Connection (Serial Connection)
When connecting two switches in series, please pay attention to the
following:
• Maximum output current (100 mA) ≥ load current + current
consumption (16 mA)
• Supply voltage ≥ operation voltage
of a load + 2 x voltage drop (2 V)
• If target moves too quickly,
switch may operate incorrectly.
• In series, switch A may operate incorrectly on startup, because
switch A is supplied power from switch B’s output.
Handling Precautions
• With serial connections the switch may be briey unusable due
to power uctuation. Check the system before use.
OR Connection (Parallel Connection)
Up to three of these switches may
be connected in parallel.
Points to be Aware of When Handling
• Do not swing the switch by the cable.
• Do not pull the cable with excessive force.
• Do not use the switch outdoors, or where it is surrounded by chem-
icals (solvents, acids, alkalies, etc.).
• If bending the cable, keep R (the radius of the bend) ≥ (the cable
diameter) x 3 at least.
• Do not bend the cable within 30 mm from the cable outlet as this
may cause wire breakage.
• Do not use the switch in a place where the cable would receive re-
peated bending stress. Doing so may break the cable.
• When disposing of an FL7M Series switch, dispose of it appropri-
ately as industrial waste in accordance with applicable bylaws and
regulations.
• Up to 100 ms power-on to ready-to-use time is.
Wiring cautions
• Route the wires of the switch separately from power lines or
through an exclusive conduit. Otherwise, electrical noise or a surge
may cause faulty operation or damage.
• If an extension of the cable is necessary, use at least a 0.3 mm2 wire
of 100 m maximum length.
• When using a commercial switching regulator, ground the FG
(Frame Ground) and G (Ground) terminals. Otherwise, switching
noise may cause faulty operation.
• When using a load to generate a transient current, connect a
current limit resistor between the load and the output terminal.
(Otherwise, the short-circuit protection may be activated.)
