Item
Power supply
Do not impose an excessive voltage on the
E2E, otherwise it may explode or burn. Do
not impose 100 VAC on any E2E DC
model, otherwise it may explode or burn.
Load short-circuit
Do not short-circuit the load, or the E2E
may explode or burn.
The E2E’s short-circuit protection function
is valid if the polarity of the supply voltage
imposed is correct and within the rated
voltage range.

Connection with no load
Make sure to connect a proper load to the
E2E in operation, otherwise it may explode
or burn.

Incorrect
The following diagram shows that the load
is short-circuited while the polarity of the
supply voltage imposed on the E2E is
wrong, in which case the E2E may explode
or burn.

Installation
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms after power
is supplied. If power supplies are connected to the Proximity Sensor
and load respectively, be sure to supply power to the Proximity Sen-
sor before supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned off.
Therefore, it is recommended to turn off the load before turning off
the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power sup-
ply has an insulated transformer. Do not use a DC power supply with
an auto-transformer.
Sensing Object
Metal Coating:
The sensing distances of the Proximity Sensor vary with the metal
coating on sensing objects.
Wiring
High-tension Lines
Wiring through Metal Conduit
If there is a power or high-tension line near the cord of the Proximity
Sensor, wire the cord through an independent metal conduit to pre-
vent against Proximity Sensor damage or malfunctioning.
Cord Tractive Force
Do not pull cords with the tractive forces exceeding the following.
Diameter
4 dia. max.
4 dia. min.
Tractive force
30 N max.
50 N max.
Mounting
The Proximity Sensor must not be subjected to excessive shock
with a hammer when it is installed, otherwise the Proximity Sensor
may be damaged or lose its water-resistivity.
