2. Functional Principle, Technical Data
2.1 Short Description
The Eltrotec Endolight FOT LED is an ideal light source for a variety of applications in industrial image pro-
cessing and automation technology as and also for endoscopy.
Eltrotec Endolight FOT LED offers a very high light intensity, a simple operating concept, and versatile remote
control options.
The light source is available with wight light color (typ. 6500 K) and compatible with fiber-optic lighting
components from Micro-Epsilon Eltrotec (light guides with a connection diameter of 15 mm). Fiber-optic light
guides with an active diameter of 4 mm can be used in conjunction with Eltrotec Endolight FOT LED.
2.2 Functions
- 800 luminous flux
(measured at the outlet of a 1800 mm light guide with an active diameter of 4 mm).
- Max. 50,000 hour LED lifetime (intensity declines to 50 %).
- Serial interface, digital-, analog- and trigger input.
- Storage of current settings if the power supply is interrupted
- Compact housing and simple system integration (M4 threaded rails on 4 sides).
Thanks to their characteristics, Eltrotec Endolight FOT LED is an intelligent and powerful LED light source for
flexible use in individual applications and larger inspection facilities.

5.3 Operation
After the initial start-up and operating mode selection, the light source can be operated via the selected
source for the intensity setting.
Mode selection On
(basic setting):
The light intensity can be adjusted using the potentiometer from no light
to 100 %.
Mode selection MP
(basic setting):
The light intensity can be adjusted using the analog input on the Multiport
from no light to 100 %.
Mode selection Off: No light is emitted. Communication via the COM port is active.
