E3X-NH
Precautions
WARNING
!
The E3X-NH is not a safety component for ensuring the
safety of people as defined in EC Directive 91/368/EEC, or
as covered by separate European standards or by any other
regulations or standards.
J AVOID DAMAGE TO THE E3X-NH
SENSOR
Do not impose any voltage exceeding the rated voltage on
•
the E3X-NH.
Do not impose 100 VAC or more on models that operate with
•
DC.
When supplying power to the E3X-NH, make sure that the
•
polarity of the power is correct.
Do not short-circuit the load connected to the E3X-NH.
•
The load must be connected to the E3X-NH in operation.
•
J REFLECTOR
Precautions for Using the E39-R3 Reflector
Use detergent, etc., to remove any dust or oil from the surfaces
where tape is applied. Adhesive tape will not be attached
properly if oil or dust remains on the surface.
The E39-R3 cannot be used in places where it is exposed to oil
or chemicals.
J MUTUAL INTERFERENCE PROTECTION
Perform two-point teaching if two to three Fiber Units are closely
mounted together. The mutual interference feature will guard
against false triggering.
J EEPROM WRITING ERROR
Write errors may result at the time of teaching due to power
failure or static noise. If any of these occur, re-teach the
amplifier.
NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4.

J SENSING A MINUTE OBJECT
This data sheet shows typical examples for detecting minute
objects. These typical examples are for reference use only,
because these example operations were tested on Units sampled
at random from a lot and the values described are average
values. Do not assume that all Units ensure such operations.
J WHEN THE POWER IS OFF
The moment power is turned off, the E3X-NH may output a pulse
signal which could affect the operation of the devices connected
to it. This will occur more often if power is supplied to the
E3X-NH from an external power supply, thus affecting the
connected timer or counter. We recommend using a separate
power supply to avoid a false signal.
For extending the cable, use wire with 0.3 mm
length of the cable should be a maximum of 100 m.
J POWER SUPPLY
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, or the Amplifier can malfunction due to the switching
noise of the power supply.
The supplied voltage must be within the rated voltage range.
Unregulated full- or half-wave rectifiers must not be used as
power supplies.
J WIRING
Never wire the Amplifier within the same conduit with power
lines. Doing so will cause induction between the lines, possibly
resulting in faulty operation or damage. Always wire the Amplifier
in a separate, dedicated conduit.
