E3S-C
● Adjusting
Optical Axis of Through-beam Sensor
The E3S-C Through-beam Models incorporates two lenses, one of
which will be used as shown in the following illustration. When using
a Slit, the Slit must be on the side where the lens to be used is located.

Water Resistance
To ensure the water resistance of the E3S-C, tighten the screws of the
operation panel cover to a torque of 0.34 N·m to 0.54 N·m.
● Others
Oil and Chemical Resistance
• Although the E3S-C is oil-resistance, refer to the following table
before using the E3S-C in places where oil may be sprayed on the
E3S-C.
• Tests were carried out with the following oils and it was certified that
the E3S-C resists these oils.

Lubricating oil
Water insoluble
machining oil

Note: 1. The E3S-C maintained a minimum insulation resistance of 100 MΩ
after the E3S-C was dipped in all the above oils at a temperature of
50°C for 240 hours.
2. When using the E3S-C in a place where an oil other than the ones
listed above is sprayed on the E3S-C, refer to the above kinematic
viscosity and ph values. The location may be suitable for the E3S-C if
the kinematic viscosity and pH values of the oil are close to the above
kinematic viscosity and pH values, but make sure that the oil does not
contain any additive that may have a negative influence on the E3S-C.
