Allen-Bradley 2755-LD4B1/A is a fixed-mount laser barcode scanner head in Rockwell Automation's 2755 High-Performance family, designed to read barcode symbols when paired with a compatible 2755 decoder in industrial automation systems. This scanner head uses a laser diode scanning mechanism and terminates with a NEMA Type 1 connector, aligning with rugged factory environments. The unit is discontinued by the manufacturer and is typically used as part of legacy Rockwell 2755 decoding setups. Read range and decode performance depend on barcode symbol size and print quality as well as the connected decoder.
