Load short-circuit
Do not short-circuit the load, or the E2E/E2E2
may explode or burn.
The E2E/E2E2’s short-circuit protection
function is valid if the polarity of the supply
voltage imposed is correct and within the
rated voltage range.

The following diagram shows that the load is
short-circuited while the polarity of the supply
voltage imposed on the E2E/E2E2 is wrong,
in which case the E2E/E2E2 may explode or
burn.

■ Precautions for Correct Use
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
Sensor 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
supply 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.
