Sensing range
• The sensing range is specified for the standard sensing
object. With a non-ferrous metal, the sensing range is
obtained by multiplying with the correction coefficient
specified below. Further, the sensing range also changes
if the sensing object is smaller than the standard sensing
object or if the sensing object is plated.

Note: Mount the protection cover so that there is no gap between it and the
sensing surface.
Others
• Do not use during the initial transient time (50 ms) after
the power supply is switched on.
• Make sure that stress by forcible bend or pulling is not
applied directly to the sensor cable joint.
Refer to General precautions.

DC 2-wire type
Wiring
• The sensor must be connected to a power supply via a load.
If the sensor is connected to a power supply without a load,
the short-circuit protection makes the sensor inoperable.
(The output stays in the OFF state and the indicator does
not light up.) In this case, rectify by connecting the power
supply via a load. Now, the sensor becomes operable.
Further, take care that if the power supply is connected with
reverse polarity without a load, the sensor will get damaged.

• For series connection (AND circuit) or parallel connection
(OR circuit) of sensors, take care of the following.
Series connection (AND circuit)
When all sensors are in the ON state,
the load voltage VRL is given by:
VRL = VCC – n × 3 (V)
Vcc: s upply voltage
(24 V DC max.)
n: number of sensors
Make sure that the load can
work properly at this voltage.
Note: T he output is generated
normally even if the indicator
does not light up properly.

Parallel connection (OR circuit)
When all sensors are in the OFF state,
the load leakage current lcc is given by:
lcc = n × 0.8 (mA) ( n: number of sensors)
Make sure that the load can work properly.
Note: T he load current in the ON state
is given by:
IL =
Vcc – 3V
Load resistance
(mA)
The load current must be
3 mA × n ≤ IL ≤ 70 mA
(n: number of sensors turned ON)

• The residual voltage of the sensor is 3 V. Before connecting
a relay as the load, take care of its actuation voltage.
(Some 12 V relays may not be usable.)

• When the sensing object is in the stable sensing range,
the LED lights up in green, and when the sensing object
is in the unstable sensing range, the LED lights up in
orange. While the LED lights up in green, the sensing is
performed stably without being affected by temperature
drifts or voltage fluctuations.
