Electrostatic Protection (ESD):


Pay attention to anti-static measures during the design and use of the BM300.

Pay attention to the measures such as wearing an anti-static wrist strap and grounding the work area.



Feature Of 2D Barcode Scanner

1. IR/Light Triggers

The combination of IR sensor and light sensor exhibits an improved sensitivity in activating the scanner to scan barcodes as they are presented, to achieve higher throughput and productivity.

2. Automatic Exposure Control (AEC)

The sensors in the LV3000U automatically adjust the brightness of supplementary lighting based on the light reflected off barcode.

3. IP54-sealed Housing

The LV3000U is environmentally sealed to anIP54 rating to prevent dust, moisture and other contaminant from entering it.

4. Unmatched Reading Performance

The LV3000U is capable of reading 1D as well as high-volume 2D barcodes on the screencovered with protective film.

5. Highly Visible Laser Aimer

The LV3000U provides a laser-generated crosshair aiming pattern that is clear and bright even in bright sunlight, ensuring first time accurate aim.

6. 1.5m Drop Resistance

The scanner withstands multiple 1.5m drops toconcrete (for six sides, three drops per side).
