Features: High-quality laser head: the use of imported high-performance laser tip, anti-oxidation can fall off, the lens design of the earthquake protection. High elastic rebound button: comfortable and durable keys and fuselage components life of up to 500 million times, the key is equipped with internal high-lever, not stuck or stick. Buzzer prompt: scan data successfully, a sound prompt, scan data failed, three sound tips. Plug and Play: the data cable and scan gun, computer connection, you can use, convenient and quick, do not charge. Smart scan: Qualcomm chip, strong decoding capabilities. Support common one-dimensional code, with high-pass strong decoding chip. Fast scan up to 120 times / second High-quality laser head: high-end process Die-casting process using alloy die-casting process, quasi-positioning optical components, a solid metal shell to protect the optical components, the stent was designed to firmly decode the circuit board and bar code engine. In any case are not shift, a large limit to ensure the stability of the performance. Seismic anti-drop: scanning gun shell added thickened shock rubber design, can withstand multiple 1.5 meter free-fall, shock and drop, can be used in any industrial environment Description: Scanning speed: 120 times / second Accuracy: 5mil Printing contrast: 35% Ambient temperature: 23 C Ambient lighting: 0-100,000 lx Maximum power: 0.247W Working voltage: (3.3V ~ 4.2V) 5% Maximum current: 65mA Operating current: 10mA (standby); 65mA (scan) Reminder mode: buzzer, LED indicator Scan mode: manual key trigger scan Interface support: RS-232, USB, PS2.
