s 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-A❏❏
Light is emitted from the projection fiber head when the self-
diagnostic inputs is ON. The sensor, however, will not operate.
E3X-F❏❏/-VG❏❏
No light is emitted from the projection fiber head when self-
diagnostic input is ON.

s SPECIAL FIBER UNITS
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.)
E32-DC200B (tube with 2.5 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.)
