IP64 Drip-proof Construction
The E6C2-C incorporates a rubber-seal bearing cover of
IP64 drip-proof construction thus ensuring ease of use in
places with water dripping or sprayed oil.
Shaft Withstands Heavy Loads
The bearing used by the E6C2-C is larger than that of the conven-
tional E6C-C, thus withstanding heavier loads.

Thrust
30 N
Protective Circuit for Output Short-
ing
The E6C2-C incorporates a circuit protecting the E6C2-C from dam-
age resulting from the incorrect wiring of output, thus ensuring ease
of use.
33% Smaller than E6C-C
The E6C2-C uses a high-performance LED indicator, custom-made
receiver element, high-density PCB, and seal bearing thus making
the E6C2-C 33% smaller than the conventional E6C-C.

Incorporating Cord to Be Pulled Out
Aslant Ensuring Ease of Mounting
and Wiring
To suit the mounting position, it was necessary to select a conven-
tional E6C-C model with a cord that is pulled out horizontally or a
model with a cord that is pulled out backwards. The E6C2-C incorpo-
rates a cord that is pulled out aslant, thus ensuring ease of mounting
and wiring while saving mounting space.
