1 About this document

The purpose of this Quickstart is to allow you to commission the RFU62 x RFID
read/write device (UHF) quickly and easily and to achieve initial read results with
transponders.

The Quickstart is valid for the regional variants listed in the “Device overview” sec‐
tion: see Device overview, page 7.

For simplicity in this document, the RFU620-10xxx read/write device is referred to
as the RFU620, unless a clear distinction needs to be made between variants.

The Quickstart describes the commissioning process for an application with an
RFU620 in ambient temperature range 0 °C to +50 °C.

Device variant RFU620-10100 (Ethernet variant, regional assignment: Europe/
South Africa) is used as the basis for the examples given, based on its default.
The optional CDB620 connection module is used as an example for the industrial­standard signal distribution of the RFU620. Other connection modules are avail‐
able. With the exception of the electrical connection, other device variants of the
RFU620 are commissioned in the same way.

2.1 Intended use

The RFU620 read/write device is an intelligent SICK-4 Dpro sensor from the
RFU62 x product family. The device is used for the automated, fixed identification
of wireless-based data cards on moving or stationary objects and their manage‐
ment.

As a compact read/write device, the RFU620-10xxx has an internal antenna that
is integrated into the housing. It processes all standard passive transponders in
accordance with ISO/IEC 18000-6C and EPCglobalUHF C1G2 in the regional UHF
carrier frequency range. Thanks to its intelligent process logic, it can be used
either as a stand-alone solution or as part of a group in a network. The
RFU620 uses its host interface to transmit the read results to an overriding com‐
puter for further processing or it can receive corresponding commands for manag‐
ing the data card (read, write, etc.) via the interface.

Intended use also includes compliance with all information in this Quickstart and
the supplementary RFU62x RFID read/write device (UHF) operating instructions.

The RFU62 x-101 xx product family consists of 3 variant series which are distin‐
guished by the data interface and the designs of the electrical connection,
for example:

•

2 or 4 screws. Screw the M6 screws max. 6 mm, M5 max. 9 mm into
the blind tapped holes. see Device description, page 5.

Mount the RFU620 on the SICK mounting accessories ordered sepa‐
rately.

3. Align the surface of the internal antenna of the RFU620 (front face) to the
data card on the object. While doing so, take into account the shape, align‐
ment, and dimensions of the antenna fields. Avoid as far as possible any
large metal surfaces positioned to the front. If this is not possible, do not
mount the antenna plane parallel with the surface.

Metal surface

4. Ensure there is no electrically conductive material (e.g., liquids) or persons
between the RFU620 and the transponder during the write or read process.
This will absorb or reflect the generated UHF field and thereby reduce the
sensing range.

Sensing range of the reading and writing field

The UHF field of the internal antenna is influenced by its environment, making it
impossible to provide a “clear” demarcation of the sensing range. Application-spe‐
cific reflections can result in both overreaches and “holes”. In addition to the read
results, the RFU620 can also output diagnostic data that provide an indication of
the write and read quality. This data can be used to achieve optimum read results
when setting up the system.

The quality of the transponder and the material of the object also determine the
sensing range. The quality of the transponder is determined by the antenna gain,
the integrated transponder chip and the related sensitivity, and the reflected
energy.

The radiation pattern shown here for the internal antenna of the RFU620 was
obtained in a reproducible environment (absorber chamber) for illustrative pur‐
poses. It may therefore only have limited applicability to your specific application.

•

Wire cross-sections in the supply cable from the user’s power system must
be designed in accordance with the applicable national standards.

•

Only connect the device to the permitted supply voltage, see Technical data

(excerpt), page 6.

•

If the supply voltage is not supplied via the optional CDB620 connection
module, the RFU620 must be protected by a separate 0.8 A slow-blow fuse
at the start of the supply circuit.

•

All circuits connected to the device must be designed as SELV circuits. The
voltage supply or power supply unit must satisfy SELV requirements in accor‐
dance with the currently applicable EN 60950-1. (SELV = Safety Extra Low
Voltage).

WARNING

Risk of injury and damage caused by electrical current!

The device is designed for operation in a system with proficient grounding of
all connected devices and mounting surfaces to the same ground potential.

Due to equipotential bonding currents between the device and other
grounded devices in the system, incorrect grounding of the RFU620 can
charge the metal housing to a dangerous voltage, cause malfunction and
destruction of devices as well as damage to the cable shielding through heat‐
ing, and thus cause cable fires.

•

Ensure that the ground potential is the same at all grounding points.

•

If the cable insulation is damaged, disconnect the voltage supply imme‐
diately and have the damage repaired.

•

For measures for eliminating hazards, see the “Electrical installation”
chapter in the RFU62x RFID read/write device (UHF) operating instruc‐
tions on the product page on the Internet at www.sick.com/RFU62x

NOTICE

Risk of damage to the device due to possible short-circuit!

The supply voltage input for the device is designed with internal circuit protec‐
tion to provide reverse polarity protection. The internal functional earth, which
also corresponds to the negative pole of the supply voltage for the device, is
connected directly to the metal housing of the device due to reasons relating
to high frequency.

If the supply voltage is polarity-reversed, this will not cause any damage pro‐
vided that the following conditions are met for the device:

The device is not connected in an electrically conductive manner, either via
other cables or via its housing, to other peripheral devices which use the
same reference potential.

4.1 Connecting the RFU620

NOTE

The USB interface of the device is used in industrial environments only as a
service interface for temporary use (e.g. for configuration, troubleshooting).
Permanent use in real operation of the system as a host interface is not
intended.

3.5 Mounting the CDB620 connection module

Mount the CDB620 connection module in the vicinity of the RFU620. When
using the serial data interfaces (RS-232), the recommended length of cable
between the devices is max. 5 m. Mount the CDB620 in such a way that the
device can be accessed at all times, see the CDB620 connection module
operating instructions.

4 Electrical installation

•

•

•

•

The electrical installation must only be performed by electrically qualified persons.
Standard safety requirements must be met when working on electrical systems.

Electrical connections between the RFU620 and other devices may only be
made or separated when there is no power to the system. Otherwise, there is
a risk of damaging the devices.

When using connecting or extension cables with an open end, make sure
that bare wire ends are not touching (risk of short-circuit when the supply
voltage is switched on). Wires must be appropriately insulated from each
other.
