Overview
SIMATIC MV340 is one of the most powerful handheld readers in
the world and is thus particularly suitable for demanding appli-
cations. It reads a wide range of direct part markings (DPM),
from linear barcodes up to 2D symbols. Different codes can be
read without having to reconfigure the device.
The device is designed for close ranges and records codes at a
distance of up to 50 mm. The optimum reading distance is 6 mm.
The special integrated lighting is ideal for a wide variety of sur-
faces and increases the contrast with stamped codes. Reading
despite fluctuating lighting conditions, low contrast, and twisted
or damaged codes are the strengths of the MV340.
The MV340 is connected via a USB or RS232 interface to the IT
system. The USB cable is included in the delivery as standard,
the RS232 cable can be ordered separately as an accessory.
■
Design
The MV340 is a fully integrated device that combines a powerful
reader unit and lighting in a rugged housing with an ergonomi-
cally shaped handle. The read process is triggered by a switch
on the handle. Feedback from the read process can be optical
via a multi-color LED, acoustic, or by means of a vibrating alarm.
The special integrated lighting unit can switch automatically be-
tween different lighting types to always provide optimal lighting
conditions for a wide range of code and surface types. Even low-
contrast codes or dot peen markings are therefore no longer a
problem.
The device is supplied with a USB cable as standard. An RS232
cable can be ordered separately as an accessory.
■
Integration
The SIMATIC MV340 is connected via USB or RS232. Free ESP
software is available for user-friendly set-up of the device. As an
alternative, the device can be installed and operated without
special software since it can also be configured by reading sup-
plied data matrix codes.
The power supply is solely via cable. If the device is connected
via USB to the host computer, the supply voltage is applied di-
rectly via the USB port. If the connection is via RS232, an addi-
tional power supply unit is required which is coupled to the
RS232 connector via Y-cable. The power supply unit is available
in three variants: EU, UK, and USA.
