on page 3.
Features
Detects glass plates without being
influenced by the processing condition of its
edges.
Stably detects on-tray glass plates even if
the glass plates are offset.

The stable detection of glass plates is possible without being
influenced by the processing condition of its glass edges (e.g.,
rounded or chamfered edges) or warps due to the weight of
the glass plates.
Note: Be sure to confirm operation before use.
The E3C-L11M ensures stable detection in a sensing range of
±10
mm or
±10°
from the center distance of glass substrates
set in cassettes or trays.

Safety Precautions
WARNING
This product is not designed or rated for
ensuring safety of persons. Do not use it for
such purpose.
Precautions for Correct Use
Do not use the product in atmospheres or environments that
exceed product ratings.
●
Mounting
The torque required to tighten each screw must be 0.71 N·m
maximum. Excessive tightening torque may damage the
Sensor and Amplifier.
●
Wiring
A maximum of 24 VDC±10% can be imposed on the E3C-
L11M. Check that the voltage of the power supply is within the
permissible range before turning on the E3C-L11M.
