June 2026<\/em><\/p>\n\n\n\n To begin with, the SFA2000A adopts 905nm semiconductor laser and TOF (Time\u2011of\u2011Flight) ranging technology. As a result, it delivers stable full\u2011scale ranging from 2m to 2000m. Furthermore, it combines Class 1 eye safety, an ultra\u2011compact lightweight design, industrial\u2011grade reliability, and low power consumption for extended battery life. Consequently, it provides a professional solution for civil UAVs, outdoor observation, engineering surveying, security inspection, and other medium\u2011to\u2011long range high\u2011precision applications.<\/strong><\/p>\n\n\n\n To begin with, the SFA2000A leverages the proven single\u2011pulse TOF laser ranging principle, integrated with a compact opto\u2011mechanical\u2011electronic design. As a result, it offers clear advantages over traditional ranging technologies in medium\u2011to\u2011long range measurement:<\/strong><\/p>\n\n\n\n To begin with, the SFA2000A achieves a ranging capability of 2000m (at 60% reflectivity, building target, visibility \u22656km), 1400m (at 30% reflectivity, 2.3\u00d72.3m target), and 1000m (at 30% reflectivity, 0.5\u00d71.7m target). Its minimum range is 2m. Furthermore, it delivers ranging accuracy of \u00b1(0.4m + d\u00d70.07%) for distances \u2264800m, and \u00b11m for distances >800m. Additionally, it offers distance resolution of 0.1m.<\/strong><\/p>\n\n\n\n In terms of physical design, the module features compact dimensions of 26mm \u00d7 25mm \u00d7 14mm (L \u00d7 W \u00d7 H) and weighs only 10.5 \u00b1 0.5g \u2013 consequently, it is lighter than an ordinary USB flash drive. Its compact integrated design enables easy integration into various micro\u2011payload devices.<\/strong><\/p>\n\n\n\n Regarding environmental adaptability, the module operates from \u201120\u00b0C to +70\u00b0C and stores from \u201125\u00b0C to +75\u00b0C. Furthermore, it withstands 1200g @ 1ms shock and 2.5g vibration, delivering industrial\u2011grade reliability with MTBF \u22651500 hours.<\/strong><\/p>\n\n\n\n For power requirements, we design the module for DC 3\u20135V wide\u2011voltage compatibility. Standby power consumption is \u22640.5mW (Power on low) and \u22640.3W (Power on high). Operating power is \u22640.75W at 70\u00b0C and \u22640.6W at \u201120\u00b0C \u2013 consequently, this low power consumption extends battery life of portable devices.<\/strong><\/p>\n\n\n\n Furthermore, the module supports single\u2011shot and continuous ranging mode switching, multiple baud rate configurations (115200\/57600\/38400\/9600bps), adjustable laser brightness from 1% to 100% (for development use only), and real\u2011time full\u2011status self\u2011diagnostics. For communication, we equip it with a standard UART (TTL_3.3V) serial interface and provide a complete communication protocol and command set, enabling low\u2011threshold secondary development.<\/strong><\/p>\n\n\n\n (Data based on standard conditions: line\u2011of\u2011sight, visibility \u22656km, relative humidity \u226460%. Smog, haze, or dusty weather may affect ranging performance. Lower target reflectivity or longer distances may reduce measurement frequency.)<\/em><\/p>\n\n\n\n Safety:<\/strong> To begin with, this product is a Class 1 eye\u2011safe laser. However, we advise avoiding direct viewing of the laser aperture to prevent potential eye strain. Furthermore, the spot calibration mode is for developer use only; laser brightness is adjustable in this mode \u2013 do not point the laser at human eyes.<\/p>\n\n\n\n ESD protection:<\/strong> Additionally, we require proper electrostatic discharge precautions. Do not touch any electronic components without appropriate protective measures. Never connect or disconnect cables while the module is powered on. Moreover, ensure correct power polarity; failure to do so may cause irreparable damage.<\/p>\n\n\n\n Window integration:<\/strong> Furthermore, if using an external window in system integration, we recommend that the window achieves a transmittance of \u226598% for the 905\u00b120nm band. When installing, ensure the thread length of countersunk screws does not exceed 3.5mm. You may apply adhesive at the seams for additional fixation.<\/p>\n\n\n\n Optical window care:<\/strong> Additionally, keep the optical lens clean. Use a blower to remove dust particles. For fingerprints, gently wipe with a cotton swab dipped in a small amount of alcohol\u2011ether mixture, then clean with a lens cloth. Do not touch the optical surface directly with fingers.<\/p>\n\n\n\n Environmental precautions:<\/strong> Furthermore, avoid prolonged use in high\u2011temperature, humid, rainy, snowy, or dusty environments. Protect the module from rapid temperature changes or strong mechanical shocks.<\/p>\n\n\n\n Modification & cabling:<\/strong> Moreover, do not disassemble, modify, or alter the module, as this will void the warranty. Use the supplied communication cable. If using a custom cable, confirm correct pin assignments to prevent TX\/RX reversal, which may cause communication errors.<\/p>\n\n\n\n Startup & communication:<\/strong> Finally, allow \u2264200ms after power\u2011on for system initialisation. Pull the POWER_ON pin high before sending commands. The default baud rate is 115200bps, which you can configure to other rates via commands.<\/p>\n\n\n\n In conclusion, the SFA2000A combines TOF technology, 2000m long\u2011range capability, 10.5g ultra\u2011lightweight design, and industrial\u2011grade wide\u2011temperature reliability. Therefore, it serves as an ideal high\u2011performance ranging component for a wide range of medium\u2011to\u2011long range measurement and embedded integration needs. From UAVs and surveying to security and inspection applications, the SFA2000A empowers smart sensing to reach farther, become lighter, and deliver greater reliability.<\/strong><\/p>","protected":false},"excerpt":{"rendered":" SunFlaser Technology (Chengdu) Launches the SFA2000A Micro Laser Ranging Module \u2013 905nm TOF, 2000m Long Range June 2026 To begin with, the SFA2000A adopts 905nm semiconductor laser and TOF (Time\u2011of\u2011Flight) ranging technology.
