INSTALLATION AND SURROUNDINGS
Do not tighten the nut with excessive force. A washer must be
used with the nut.
Shielded Model
Part B Part A
Note: The table below shows the tightening torques for part A
and part B nuts. In the above example, the nut is on the
sensor head side (part B) and hence the tightening torque
for part B applies. If this nut is in part A, the tightening
torque for part A applies instead.

EFFECTS OF SURROUNDING METAL
When mounting the E2EQ within a metal panel, ensure that the
clearances given in the following table are maintained. Failure to
maintain these distances may cause deterioration in the

SENSING OBJECT
Sensing Object Material
The sensing distance is reduced for non-magnetic metals. The
sensing distance for non-magnetic metal foils less than 0.01 mm
thick is the same as that for magnetic metals. However, if the foil
becomes so thin (e.g., from vaporization) that it loses its
conductivity, then it will become undetectable.
Metal Plating
The sensing distance will change if the sensing object is plated.
The following table shows the sensing distance of a plated object
as a percentage of the sensing distance of an un-plated object.

TURNING ON THE POWER
The proximity Sensor will begin sensing no later than 100 ms after
the power is turned on. If the load and the Proximity Sensor operate
on different power supplies, the Proximity Sensor must always be
turned on first.
J
LEAKAGE CURRENT EFFECTS
Even when the Proximity Sensor is OFF, a small current will flow in
the circuit (see Leakage Current Characteristics). If input to C-MOS
or transistor, or other circuit element is unchanged due to leakage
current, poor operation and inconsistency may result. In this case
make sure that the bleeder resistance (R
2
) is sufficient to dampen
the leakage current.

When using relay or PC loads, remember that the residual voltage
of the Proximity Sensor is 3 V (A 12-VDC relay cannot be switched)

SERIES CONNECTION (AND CIRCUIT)
When constructing AND circuits by connecting 2 or more Proximity
Sensor's in series, the voltage over the load V

will be lower than

times n, where n is the number of Proximity
Sensors connected in series.

PARALLEL CONNECTION (OR CIRCUIT)
When constructing OR circuits by connecting 2 or more Proximity
Sensors in parallel, the leakage current through the load will be 0.8
mA times n, where n is the number of Proximity Sensors connected
in parallel.

DIRECT CONNECTION TO A POWER

Never connect the Proximity Sensor directly to a power supply
without a load in the circuit.
