ICR 840 – the new 2-D code reader with a matrix sensor
Waldkirch, April 2005 – SICK is presenting the new ICR 840 2-D code reader at the Hanover Industrial Trade Fair 2005. The device is intended for applications in which directly marked stationary objects, e.g. electronic components or parts supplied to the automotive industry, require identification. The CMOS matrix sensor of the ICR 840 offers a resolution of 1.3 megapixels and an image repeat rate that can be adapted for the particular task. Integrated software assistants simplify commissioning and Ethernet connection. The ICR 840 is the efficient solution for direct part marking (DPM) identification, which is gaining in importance with increasing miniaturisation and the ever-growing demand for traceability.

Whether by ink jet, laser or needle-printing – the variety of directly marked objects in production and logistics, as well as in document handling or in pharmaceuticals and laboratory use, is growing. While the familiar ICR 850, with its scanning frequency of 15 kHz, is intended for applications in which objects must be identified while in motion, the new ICR 840 is a good technical and economical alternative for stationary tasks involving, for example, electronic components, airbag cartridges, address information or unique identification marks such as Data Matrix codes on medical products.

Large high-resolution image field thanks to CMOS

The ICR 840 operates with a modern, 1.3 megapixel CMOS matrix sensor. The image repeat rate is 25 Hz with an image field of 45 x 35 mm² and a resolution of 0.15 mm. A 2-D code detected within this field is reliably read.

If necessary, the reading field can be restricted, to allow the image repeat rate to be increased to, say, 60 Hz (with a comparable VGA resolution of 640 x 480 pixels) when the location of the bar codes on the target object is known, e.g. because of specific process conditions. The ICR 840 read information or images can also be transferred via the integrated Ethernet interface.

Simply installed – simply versatile

With its CLV setup interface, the ICR 840 offers a familiar look and feel during commissioning. Supplementary software assistants support users during mechanical adjustment, teach-in of the code to be detected, and Ethernet connection. The 2-D code reader is then capable of versatile application, e.g. for the identification of components, housings and circuit boards in the electronics industry, for automobile components of all sorts, and numerous other objects.
