Zebra SE4750MR – Mid-Range 2D Scan Engine

The Zebra SE4750MR is designed for applications where operators need a greater scanning distance than a standard 2D scan engine.

It provides additional flexibility when scanning cartons, warehouse shelving, pallets, and barcodes that are not always positioned directly in front of the operator.

Key Advantages

• Supports common 1D and 2D barcodes
• Mid-range barcode scanning
• Suitable for warehouse shelves
• Greater flexibility in scanning distance
• Zebra decoding performance

Recommended for: Warehouses, logistics centers, distribution centers, inventory management, and applications requiring medium-distance barcode scanning.

Zebra SE55 / SE5500 – Long-Range 2D Scan Engine

The Zebra SE55 / SE5500 long-range scan engine is designed for demanding warehouse applications where operators need to capture barcodes from significantly greater distances.
