JEF500
Intended use
The JEF500 is a non-contact proximity measurement sensor
in standalone mode. As an industry-standard line camera for
measuring distance, it calculates radial distances relative to
its measurement origin. The JEF500 outputs the continuously
generated raw data as an event on demand (subscription) in
real time via one of its two Ethernet ports. An object trigger
(internal or external) controls the beginning and end of
the measurements. The user can process the data on his/
her PC for 3D representation or analysis. For this purpose,
a corresponding driver must be developed for the detected
objects.
The JEF500 is designed for inside use with a scanning range
of 0.4 to 2 m (1.31 to 6.56 ft) at a constant depth of focus.
These operating instructions serve to quickly and easily
commission the JEF500. They allow the user to obtain initial
output of measured values with the default setting.
Detailed information about the mechanical and electrical
installation, as well as the data output format of the measured
values are available in JEF300/500 Technical Information.
In-depth information about the conguration is available in
the online help of the SOPAS ET conguration software.
The information can be accessed on the enclosed data
carrier (DVD) or on the JEF500 product site on the web
(www.mysick.com/en/jef500)
Safety information
• Read these instructions before commissioning the JEF500
in order to familiarize yourself with the device and its
functions.
• The JEF500 corresponds to laser class 2. The human eye
is not at risk when accidentally exposed to the laser radia-
tion for short periods of time (up to 0.25 s).
When intentionally exposed to the laser beam for longer
periods of time, the retina of the eye may be damaged
( see „Laser radiation danger!, page 4“).
• Electrical connections between the JEF500 and other
devices may only be made when there is no power to the
system. Otherwise, the devices may be damaged.
• Turn the swivel connector unit with the electrical connec-
tions max 180° from end position to end position.
• Conducting cross sections of the supply cable from the
customer's power system should be designed in accor-
dance with the applicable standards.
If the supply voltage for the JEF500 is not supplied via the
optional CDB620 connection module, the JEF500 must be
protected by a 0.8 A slow-blow external fuse at the begin-
ning of the supply cable.
• The electrical circuits connected to the JEF500 must
be implemented as SELV or PELV electrical circuits
(SELV = Safety Extra Low Voltage; PELV = Protective Extra
Low Voltage).
• Only use the device under reliable environmental conditions
( see „Technical specications (excerpt), page 6“ and
„Danger of potential equalization currents, page 6“).
• Opening the screws of the JEF500 housing will invalidate
any warranty claims against SICK AG.
• The JEF500 does not constitute personal protection equip-
ment in accordance with the respective applicable safety
standards for machines.
Commissioning and conguration
Operating principle of the JEF500
The JEF500 deects a laser beam repeatedly in a circular
scan on a plane at a high rotary frequency. If the laser beam
scans an object, it produces a red scan line as an active line
(for the human eye).
The scanned object reects a portion of the light back.
From the entire process, the JEF500 calculates the distance to
the object on evaluated, dened angular positions of the beam
deection. In its eld of view (sector, scanning angle 45°),
the JEF500 captures the contour it "sees" in the line of the
object in two dimensions. The data generated per scan in the
form of length and reectivity values refer to advancing angular
positions. The JEF500 outputs this data volume (default) to its
polar coordinate system unltered.
The JEF500 is available in two versions for the application
solution normally implemented for measurement from above.
The line scanner (2D) detects moving objects that pass
through the scan line oriented rectangulary to the transport
direction. By advancing, an image is taken bit by bit so as
it were.
The device outputs the measured value in combination with
speed information. At a constant feedrate > 0, the congured
device generates internal ticks. If the feedrate is irregular,
for example, an attached incremental encoder continuously
feeds movement information to the device as a reference
base.
The line scanner with oscillating mirror (3D) automatically
scans the object with the laser beam at rest or minimal
feedrate. It also deects the laser beam rectangulary to the
scanning direction with a dened angular speed in a range of
max 40° asymmetrically around the zero position.

JEF500 line scanner with oscillating mirror: Measurement of stationary
objects from above
The user can locate the measurement origin of the JEF500
as required in its coordinate system of the application.
The JEF500 itself provides no position information except the
deection angle of the oscillating mirror depending on type.
A mark on the housing identies the measurement origin of
the line scanner ( see in „Description of the device, page
3“). The measurement origin of the line scanner with oscillat-
ing mirror â is transferred to that of the line scanner.
Moved
35.24 mm (1.39 in), it lies virtually outside the housing based
on the point at which the light impacts the oscillating mirror.
For absolute measurements, these measurement results are
adjusted if necessary (see measurements in the "Measured
value output" chapter in the Technical Information).
Step 1: Electrical installation
1. Connect the PC to the communication interface of the
JEF500 (recommendation: Ethernet, 4-pin M12 socket).
2. Turn on and start the PC.
3. Provide power to the JEF500 (17-pin M12 plug).
After successful initialization and self-test, the "Ready" LED
illuminates green.

Step 2: Mounting and alignment
1. Depending on the country of use, cover the US-English
laser warning label with one of the provided language
versions (German or French).
2. Optional: Mount the JEF500 to a mounting accessory
ordered separately (mounting kit 1, 2 or 3), see the
"Mounting" chapter in the Technical Information. The kits
allow for ne adjustment in 2 or 3 axes.
3. Otherwise, when measuring from above, use at least
two M5 screws to mount the JEF500 at the place of use
above the measuring point to a prepared bracket. Use the
threaded mounting hole in the housing in pairs (top or
bottom next to the connections, see „Description of
the device, page 3“). Insert the screws into the threaded
mounting holes max 5 mm (0.19 in).
4. Observe the following conditions for the JEF500:
• Mount as shock and vibration-free as possible
• Clear view of the object to be measured
