External Diagnostic Input Function
With this function, light projection can be stopped when desired.
The operation of the sensor can be checked with this function before
the E3X is placed into actual operation.
E3X-Ajj
Light is emitted from the projection fiber head when the self-diag-
nostic input is ON. The sensor, however, will not operate.

The following special accessories are available (order separately).
Contact your OMRON representative for the details.
Fiber Units with Special Length of Stainless
Steel Tube
Fiber with different lengths of stainless steel tubes are available.
Applicable Models
E32-TC200F (tube with 0.9 dia.)
E32-TC200B/DC200F (tube with 1.2 dia.)

Appearance
L
The length can be ordered in increments of 10 mm between
10 mm min. and 120 mm max.
Tolerance: +1.0 mm if L is 40 mm or less. and +2.0 if L is more
than 40 mm. (Note that standard Fiber Units have a 90-mm or
40-mm long stainless steel tube.)
