Precautions
This product is not designed or rated for ensuring
safety of persons. Do not use it for such purpose.
Never use this product with an AC power supply.
Otherwise, explosion may result.
Safety precautions
Load short-circuit
Do not short-circuit the load, or the E2B may be damaged.
The E2B’s short-circuit protection function will be valid if the polarity
of the supply voltage imposed is correct and within the rated voltage
range.
Wiring
Be sure to wire the E2B and load correctly, otherwise it may be dam-
aged.
Connection with no load
Be sure to insert loads when wiring. Make sure to connect a proper
load to the E2B in operation, otherwise it may damage internal ele-
ments.
Do not expose the product to flammable or explosive gases.
Do not disassemble, repair, or modify the product.
Correct use
Designing
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.
Effects of surrounding metal
When mounting the proximity sensor within a metal panel, ensure
that the clearances given in the Table1 are maintained. Failure to
maintain these distance may cause deterioration in the performance
of the sensor.
