Note: The maximum load
current varies depending on the ambient
temperature.
Conditions for the load
(1)
The load should not be actuated by the leakage current (0.8mA)
in the OFF state.
(2)
The load should be actuated by (supply voltage - 3V) in the ON state.
(3)
The current in the ON state should be between 3 to 70mA DC.
In case the current is less than 3mA, connect a bleeder resistance
in parallel to the load so that a current of 3mA, or more, flows.
CAUTIONS
2
٨
If power is supplied from a commercial switching regulator,
ensure that the frame ground (F.G.) terminal of the power
supply is connected to an actual ground.
٨
Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
٨
Do not use during the initial transient time (50ms) after the
power supply is switched on.
٨
Extension up to total 50m is possible with a 0.3mm2, or more, cable.
However, in order to reduce noise, make the wiring as short as possible.
SENSING RANGE
3
٨ Please use it by 1.8mm or less.
However, this value is a value over
a standard detection object (iron
1515t1mm). With a non-ferrous metal, the sensing range is
obtained by multiplying with the
correction coefficient specified on
the right.
This bag is a product made from polyethylene. Even if it burns, harmful gas is not generated.

٨٨Keep in mind that detection distance becomes short when a
detection object is small.
Further, the sensing range also changes if the sensing object
is plated.
MOUNTING
4
٨
Do not use a washer between
the sensor and the mounting
screw.
The tightening torque should
٨
be 0.5N㨯m or less.
To mount the sensor with a
٨
nut, the thru-hole diameter
should be Ǿ3.4mm. With the
attached mounting screw and
nut, take care that the thickness of the mounting plate
should be 2.3mm or less.
٨
If a screw other than the attached screw to use a M3
truss head screw.
Do not use a flat head screw
or a pan head screw.
٨Influence of surrounding metal
When there is a metal near the sensor, keep the minimum
separation distance specified below.
Refer to the figures shown on the reverse side.

٨Mutual interference prevention
When two or more sensors are installed in parallel or face to
face, keep the minimum separation distance specified below
to avoid mutual interference.
Refer to the figures shown on the reverse side.
Between 'I' type and non 'I' type
Between two 'I' types or two non 'I' types
Note: Close mounting is possible for up to two sensors. When mount-
ing three sensors or more, at an equal spacing, in a row, the
minimum value of dimension 'H' should be 2mm.
