Keyence SR-2000 1D/2D Code Reader
The SR-2000 from Keyence is a full-range 1D/2D code reader built for flexible identification tasks on production lines. Specifically, its CMOS image sensor delivers 2048 x 1536 pixels, which supports reliable reading of small codes at long distances. Moreover, auto focus removes manual lens adjustment, so operators can switch between products without downtime. The SR-2000 suits logistics sorting, automotive traceability, and electronics assembly.
Technical Specifications
The sensor is a CMOS image sensor with 2048 x 1536 pixels. Minimum resolution reaches 0.040 mm for 2D codes and 0.082 mm for barcodes. The reading distance spans 100 to 2,000 mm, covering both close-up and long-range jobs. At 800 mm, the field of view measures 263 x 197 mm. This wide range means one reader model can handle multiple line positions.
The light source is a high-intensity red LED, while a high-intensity green LED serves as the pointer light. Besides, the green pointer helps operators align the reader without guessing the target area. Supported 2D codes include QR, MicroQR, DataMatrix (ECC200), GS1 DataMatrix, PDF417, MicroPDF417, GS1 Composite, and DotCode. Supported barcodes include CODE39, ITF, 2of5, NW-7 (Codabar), CODE128, GS1-128, GS1 DataBar, CODE93, JAN/EAN/UPC, Pharmacode, and Postal codes.
I/O and Communication
The SR-2000 provides two control inputs with bidirectional voltage. Maximum input voltage is 26.4 VDC, and the minimum ON voltage is 15 VDC. Additionally, three photo-MOS relay outputs handle up to 30 VDC and 50 mA per output, with 100 mA total.
Built-in ports include Ethernet (10/100BASE-TX), RS-232C, and USB 2.0 Full Speed. Supported protocols cover TCP/IP, EtherNet/IP, PROFINET, KV STUDIO, MC Protocol, and FTP. Serial options include no-protocol, MC, and SYSWAY. Therefore, the reader integrates easily with PLCs, PCs, and factory networks.
Electrical and Environmental Data
The supply voltage is 24 VDC +/-10%, and current consumption is approximately 1,600 mA. The operating temperature range is 0 to +45 °C, while storage temperature spans -10 to +50 °C. Relative humidity stays between 35 and 85% RH with no condensation. Furthermore, the housing carries an IP65 protection rating, so it resists dust and water jets on the line.
Installation Guide
First, mount the SR-2000 on a bracket at the planned reading distance. Next, connect the 24 VDC supply and confirm the polarity. Then, attach the Ethernet or RS-232C cable to the host device. After that, run auto focus and teach the target code through the setup software. Finally, test read rates at the slowest and fastest line speeds.
Keep the reader away from direct sunlight and strong ambient light. Also, clean the front window regularly in dusty environments. For network setups, assign a fixed IP address to avoid connection drops.
Packaging List
Shipping is available via Fedex, UPS, and DHL.
