The Datalogic TD1120-BK-90K1 ships as a three-unit kit, each scanner connecting to a USB host via cable for straightforward, battery-free operation. At the heart of each unit is a linear imager capable of 4 mil maximum scan resolution with an omni-directional scan pattern, autodiscriminating all standard 1D codes plus GS1 DataBar Expanded Stacked, GS1 DataBar Stacked, and GS1 DataBar Stacked Omnidirectional. Depth of field reaches 3.2 in at 7.5 mil on Code 39, extending to 6 in at 13 mil on EAN-13, with a maximum scanning distance of 5.91 in. Reading angles of 70 degrees skew, 65 degrees pitch, and 45 degrees roll accommodate varied presentation, while a 25% minimum print contrast enables reliable reads on lower-quality labels. The scanner tolerates ambient light up to 20000 lux and withstands repeated drops from 1.5 m onto concrete, backed by an IP30 rating. At 5.40 oz and measuring 6.7 in tall, 2.7 in wide, and 4.1 in deep, the black handheld chassis suits library, government, industrial, and retail environments.
