The 2755-L7RB model from Allen Bradley functions as a reliable medium to high-speed barcode laser scanner. Enclosed in cast aluminum with a NEMA Type 4 rating, it ensures protection against significant environmental factors. This scanner has a manageable weight of 7.5 pounds and operates using a focused helium-neon laser. The laser features a wavelength of 632.8 nanometers, ensuring effective scanning capabilities in various settings.
In terms of power specifications, the scanner has a maximum power consumption of 1.5 milliwatts, with a minimum OFF-state voltage requirement of 11 volts DC. For indication purposes, it includes two LED indicators that display the "Power On" and "Valid Read" statuses.
The 2755-L7RB scanner supports two scanning speeds based on the scan head in use. The medium-speed L7 scan head offers a fixed scan rate of 350 scans per second, while the high-speed L9 scan head increases that to 800 scans per second. The scan sweep angle differs as well; the L7 head provides a sweep angle of 47 degrees, compared to the 27 degrees of the L9 head.
The scanning range extends from 3.5 to 50 inches for the L7 scan head, while the L9 scan head covers a range of 5 to 30 inches from the scan window. Depth of field specifications are identical to the scan range for both scan heads. This scanner is rated to operate at temperatures from 32°F to 131°F, ensuring consistent performance across a wide range of conditions.
