Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use the product in atmospheres or environments that exceed
product ratings.
● Wiring
M8 Metal Connector
• Be sure to connect or disconnect the metal connector after turning
OFF the Sensor.
• Hold the connector cover to connect or disconnect the metal
connector.
• Secure the connector cover by hand. Do not use any pliers,
otherwise the connector may be damaged.
• The proper tightening torque range is between 0.3 and 0.4 N·m. Be
sure to tighten the connector securely, otherwise the specified
degree of protection may not be maintained or the connector may
be disconnected due to vibration.
● Mounting
Sensor Mounting
Use M3 screws to mount the sensor and tighten each screw to a
maximum torque of 0.53 N·m.
E3Z
● Oil-resistant Models
Oil Resistance
• Although the E3Z-@@@K Sensors have oil-resistant specifications,
performance may be affected by certain types of oil. Refer to the
following table.
• E3Z-@@@K Sensors are tested for resistance to the oils given in
the following table. Refer to the information in the table when
deciding which type of oil to use.

Note: 1. The E3Z maintained a minimum insulation resistance of 100 MΩ after
it was dipped in all the above oils for 240 hours.
2. When using the Sensors in environments subject to oils other than
those listed above, use the figures for kinematic viscosity and pH from
the table as general guidelines. Additives and other substances
contained in oils may affect the E3Z. Be sure to consider this before
use.
