Reading of 1D barcodes and 2D Data Matrix ECC200 codes for product traceability and identification is available under hazardous-area conditions with the SICK ICR840-2 Atex Image Code Readers.

The readers bring efficient manufacturing data control to Zone 1 and 2 processes.

Two Atex-certificated models are available: the SICK IP65 rated ICR840-2 Atex reader for Zone 2 operation; and, for Zone 1 operation, the Iscan300 1D/2D reader, which incorporates an ICR840-2 series reader in a bespoke Extronics Atex II 2GD EEx d IIC T6 IP66 housing.

In both models, the ICR840-2 code readers deliver high-reliability data reading to overcome weak contrasts, misaligned, dirty and poor markings, whether on labels, cartons or directly marked on the product.

The ICR840-2 Atex Series extends 1D and 2D barcode-data availability to Zone 1 and Zone 2 manufacturing processes such as paints, chemicals, pharmaceuticals, flammable gases and solvent processes, and high-dust and fine-powder conditions.

Identification, coding and traceability can now be extended throughout these operations.

The choice of ICR840-2 Atex Series models in Zone 1 or Zone 2 formats includes long-range and high-speed options with reading and decoding rates to 60 images a second.

Popular 1D and 2D codes can be read in any orientation.

The image-code readers can be easily selected to meet specific application needs with side- or front-mounted reading windows and the integrated, controllable LED illumination ensures optimum reading even of curved objects.

Live picture output from the image-code readers is available through a choice of interfaces or Ethernet to integrate the ICR840-2 Atex series with existing data environments.

The Autosetup feature in the ICR840-2 series’ firmware enables the scanner to be configured and optimised in seconds and for Ethernet with File Transfer Protocol to be established automatically without any specialist operator knowledge.

To complement the ICR840-2 Atex series, SICK has also published a guide to direct part marking (DPM), which offers users an unbiased view of the whole extent of techniques, from marking to illumination and scanning.
