When two or more sensors are installed in parallel or face
to face, keep the minimum separation distance specified
below to avoid mutual interference.
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 plated.
Do not use during the initial transient time [10 ms (DC
2-wire type: 50 ms)] after the power supply is switched on.
The output does not incorporate a short-circuit protection
circuit. Do not connect it directly to a power supply or a
capacitive load (excluding the DC 2-wire type).
To solder the terminals of the sensor and connector CN-13,
observe the following conditions.

Wiring
Series connection (AND circuit)
Note: The output is generated normally
2-color indicator (Normally open type only)
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 inop-
erable. (The output stays in the OFF state and the indica-
tor 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.
The residual voltage of the sensor is 3 V. Before connect-
ing a relay at 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 red.
While the LED lights up in green, the sensing is performed
stably without being affected by temperature drifts or
voltage fluctuations.

even if the indicator does not light
up properly.
