A warning notice indicates real or potential danger. This should protect you against
The RFH620 RFID device is an intelligent sensor for the automatic recognition and
decoding of 13.56 MHz, ISO 15693 compliant RFID transponder signals e.g. placed on
objects in a conveyor system.
The RFID device enable the bi-directional communication with a host for, e.g., further
processing.
The intended use of the RFID device results from the following description of the
function:
¾ In a reading station/situation the RFH620 could be installed in a holder, either on
the side of a conveyor system (side reading) or under it (reading from below)
¾ In a writing station/situation the RFH620 gets the date to be written from the host
system
¾ The LED’s in the front antenna panel could be switch by either the system
depending on the reading result or by the host via command language.
¾ The RFID device transfers the reading data via the host interface to a superordinate
host computer for further processing.
¾ The RFH620 could be configured/operated using the SOPAS-ET configuration
software that runs on a standard client PC provided by the customer or via
command language. Communication takes place using RS-232 or Ethernet.
Any warranty claims against SICK AG shall be deemed invalid in the case changes to
the RFH620, such as opening the housing, this includes modifications during
installation and electrical installation or changes to the SICK software.

When the RFH620 is switched off, the following data is lost:
¾ Application-specific parameter sets in the bar code scanner that were only saved
temporarily in the device
¾ The last reading result of the bar code scanner
¾ Daily operating hours counter of the RFH620
3.1.2 2.3.2 Switching the RFH620 back on
¾ Switch on the power supply to the RFH620 (the connection module) back on
- or -
¾ Connect the 15-pole D-Sub-HD connector of the RFH620
The RFH620 starts up using the most recent permanently saved configuration. The
daily operating hours counter is reset.

2.4Environmental Conditions
The RFI341 is designed to cause minimum impact to the environment.
The RFH620 consumes typically < 4,5W with 24V DC ± 10%.
3.1.4 2.4.2 Disposal of the device after decommissioning
SICK AG will not currently accept the return of any devices which can no longer be
operated or repaired.
-Inoperable or irreparable devices must be disposed of in an environmentally
friendly manner and in accordance with valid country-specific waste disposal
guidelines.
The design of the RFID device allows for its separation as recyclable secondary raw
materials and hazardous waste (electronic scrap).

3Product Description
This chapter describes the design, the features and the functions of the RFH620 RFID
device. The RFID works at a frequency of 13.56 MHz and reads passive ISO/IEC
15693 tags.
¾ For installation, electrical installation and startup assistance as well as for the
application specific configuration of the RFH620 using the SOPAS-ET
configuration software, please read this chapter prior to carrying out any of the
tasks.
3.1Setting up the RFH620
The RFH620 consists of an integrated antenna and an electronic unit with an integrated
decoder. The RFID field enters via the black top plastic part of the housing. The
RFH620 (depending on the version) is electrically connected by a revolving connector
unit with two connections.

3.5 RFH620 method of operation
The RFH620 is an intelligent sensor system for automatic and non-contact detection and
decoding of SISO/IEC15693 compliant transponders. In principle, the transponders can
be detected on any side of still or moving objects in a conveyor system. Several RFID
devices can be combined to allow detection of several sides in one passage (multi-side
reading).
The RFH620 creates a high frequency field to recognise transponders. The transponder
itself generate out of the field the power for operation and the data send from the RFID
device and respond data to the interrogator using field load modulation. The size of the
reading field depends mainly on the used transponder (size and Q-factor) and the
environment (metal objects).
Figure 3-6: HF Technology – principle overview
To control a process, external sensors could deliver information via the reading pulse,
the object distance and the conveyor speed (increment). The reading/writing results are
output to the RFH620 data interfaces and forwarded to a host/PC.
