UDL120

1. General

The UDL120 contains an integrated RFID antenna for contactless reading of transponders
fixed on storage racks. It has been designed for fast and faultless electronic recognition of
goods in transit (i.e. palettes) and is increasingly used within electronic inventory control
systems.

The reader can be mounted directly onto the fork carrier between the forks of a forklift.
Due to its flat mounting height (installation depth only 40 mm) any contact to the
transported goods will be avoided. Solid metal side cheeks (optionally available) prevent
the reader from being damaged by the transported goods and mounting on buffers
provides reasonable absorption of shocks and vibrations.

An ultrasonic sensor in the middle of the housing (optional) detects loading of the forks
and reports it to the control unit (terminal) of the forklift. This will initiate a reading process,
in which the transponder fixed to the storage rack is being read.
The reading result contains the defined storage position of the rack using the specific
transponder ident number and is instantly being reported to the terminal.
The communication between antenna and terminal can either be carried out via cable
using RS485 or wireless via Bluetooth™.
For power supply the reader requires a power connection directly at the fork carrier of the

lift mast (12...24 V/DC).

As this document is solely intended for application of the UDL120 on forklifts, the metal steel sides
(Protection Set 1) are included into all image presentations for reasons of clarity.
