Safety Precautions
Precautions for Safe Use
This product is not designed or rated for ensuring safety of
persons. Do not use it for such purposes.
Power Supply
Do not impose an excessive voltage on the E2A, otherwise it
maybe damaged. Do not impose AC current (100 to 240 VAC)
on any DC-model, otherwise it may be damaged.
Load Short-circuit
Do not short-circuit the load, or the E2A may be damaged.
The E2A’s short-circuit protection function will be valid if the
polarity of the supply voltage is correct and within the rated
voltage range.
Wiring
Be sure to wire the E2A and load correctly, otherwise it may
be damaged.
Connection with No Load
Be sure to insert a load when wiring. Make sure to connect a
proper load to the E2A during operation, otherwise it may
damage internal elements.
Do not expose the product to flammable or explosive
gases.
Do not disassemble, repair, or modify the product.
Precautions for Correct Use
Designing
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms after
power is supplied. If separate power supplies are connected
to the Proximity Sensor and load, be sure to supply power to
the Proximity Sensor before supplying power to the load.
Effects of Surrounding Metal
When mounting the E2A within a metal panel, ensure that the
clearances given in the following tables are maintained.
Power OFF
The Proximity Sensor may output a pulse signal when it is
turned OFF. Therefore, it is recommended that the load is
turned OFF before turning OFF the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power
supply has an insulated transformer. Do not use a DC power
supply with an auto-transformer.
Mutual Interference
When installing two or more Sensors face-to-face or side-by-
side, ensure that the minimum distances are maintained.
Wiring
High-tension Lines
Wiring through Metal Conduit:
If there is a power or high-tension line near the cable of the
Proximity Sensor, wire the cable through an independent
metal conduit to prevent against Proximity Sensor damage or
malfunctioning.
Cable Extension
The standard cable length is less than 200 m.
The tractive force is 50 N.
