Overview

The stationary code reading systems read various two-dimen-

sional (2D) codes and one-dimensional (1D) barcodes. Some

readers also feature functions for measuring the marking quality

(verification) for process control purposes, and for text recogni-

tion (optical character recognition, OCR). All devices can be

easily and flexibly integrated into the automation system thanks

to standardized, industry-compatible interfaces and function

blocks.

SIMATIC MV420

The SIMATIC MV420 series is particularly suitable for close-up to

mid-range reading distances (approx. 10 mm to 400 mm).

SIMATIC MV420 is an optical code reading system that has been

specially designed for detecting and evaluating a variety of ma-

chine readable codes in the packaging industry (e.g. F&B, phar-

maceuticals and tobacco) and industrial production (e.g. auto-

motive, electronics and solar). The list of readable codes

includes all standard matrix and bar codes which can be reliably

detected - mostly independent of the printing technology and

carrier medium used. One key feature of the unit is its ability to

read data matrix codes (DMC). The SIMATIC MV420 device fam-

ily is flexible, reliable and easy to use.

Besides this, two different lenses are available for the SIMATIC

MV420 which can be adjusted to the required reading distances.

In addition, various powerful integrated illumination systems are

available. The models can be ordered as preconfigured or freely

combinable. The particularly compact enclosures have a high

IP67 degree of protection.

SIMATIC MV440

SIMATIC MV440 is an optical code reading system that has been

specially designed for detecting and evaluating a number of ma-

chine readable codes in industrial production. The SIMATIC

MV440 device family is characterized by very high reading reli-

ability, high-speed reading and flexible process interfacing. The

product is also rugged, has a high degree of protection and is

easy to use. The professional decoding software is suitable for

almost all types of marking, especially for sophisticated "direct

part marking", on a wide range of different carrier materials.

With the "Veri-Genius" verification license, MV440 code readers

are able to verify the marking quality of codes in accordance

with the applicable standards. The device determines the quality

of the applied code and helps you ensure the readability using

the following process steps. Verification can be performed

simultaneously with the other functions, e.g. 1D and 2D code

reading.

With the "Text-Genius" text recognition license, MV440 code

readers can be used for text recognition (optical character rec-

ognition, OCR). Text recognition can be performed simultane-

ously with the other functions, e.g. 1D and 2D code reading.

The "Pat-Genius" object recognition licence lets you perform ob-

ject recognition (classification), position detection, presence

check, completeness check and text recognition (based on the

contour of any character or symbol). The object recognition can

also be combined with the other functions.
