Optical axis position of through-beam model
Unlike the conventional product, the through-beam model has
two lenses, but the one actually used is as shown below.
When fitting the slit, use it after matching the slit hole with the
used lens.
(Horizontal model) (Vertical model)
Lens in use.
The slit must be on this side.
Lens not in use.
Water Resistance
To ensure water resistance, tighten the operation panel cover
screws to 0.34 Nm to 0.54 Nm torque.

Miscellaneous
Oil resistance/chemical resistance
• Though E3S-C has a high oil resistance, it may not be able
to exhibit its performance depending on the oil type. Use oil
in compliance with the following table.
• Regarding the oil resistance of E3S-C, it has passed tests
on the oils given in the following table. Refer to the table for
examining the oil to be used.

Note: 1 . The E3S-C was immersed in the oils in the above table at 50°C for 240
hours, and passed the test of 100-M or more insulation resistance.
2 . For use in the environment where the E3S-C is exposed to the oil other
than those in the above table, use the dynamic viscosity and PH in the
above table. Pre-examine the oils since the sensor may be affected by
additives and like in the oils.
