Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

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.

● 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 M

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.
