Keyence SR-2000W Ultra-Wide Code Reader

Keyence SR-2000W 1D/2D Code Reader

The SR-2000W from Keyence is an ultra-wide field of view model in the SR-2000 code reader series. Specifically, it captures a much larger image area than the standard model, so one unit can read several codes in a single shot. This design suits pallet scanning, carton sorting, and multi-lane conveyor systems. Moreover, auto focus keeps the image sharp across the working range without manual adjustment.

Technical Specifications

The image sensor is a CMOS sensor with 2048 x 1536 pixels. Minimum resolution is 0.063 mm for 2D codes and 0.082 mm for barcodes. The reading distance spans 50 to 1,000 mm, which covers short-range and mid-range tasks. At 800 mm, the field of view reaches 707 x 530 mm. Therefore, the SR-2000W handles wide targets that would need two standard readers otherwise.

The light source is a high-intensity red LED, and a high-intensity green LED acts as the pointer light. Besides, the green pointer shows the capture area clearly during setup. 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

Two control inputs accept bidirectional voltage up to 26.4 VDC, with a minimum ON level of 15 VDC. Additionally, three photo-MOS relay outputs handle 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. Consequently, the reader connects to most PLC platforms and host systems without extra gateways.

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 rating for dust and water jet protection.

Installation Guide

First, mount the SR-2000W at a height that covers the full target width. Next, connect the 24 VDC supply and check the wiring polarity. Then, link the Ethernet or RS-232C cable to the controller. After that, run auto focus and teach each code position through the setup software. Finally, test reads at the lowest and highest line speeds.

Keep strong ambient light away from the reading zone. Also, clean the front window regularly in dusty areas. For wide conveyor setups, align the reader center with the middle of the lane.

FAQ

Q1: How does the SR-2000W differ from the standard SR-2000?
A: The SR-2000W offers a wider field of view, reaching 707 x 530 mm at 800 mm. Its reading distance is shorter, from 50 to 1,000 mm.

Q2: What is the field of view at 800 mm?
A: At 800 mm, the field of view measures 707 x 530 mm, which allows multi-code reading in one capture.

Q3: Which network protocols does the SR-2000W support?
A: It supports TCP/IP, EtherNet/IP, PROFINET, KV STUDIO, MC Protocol, and FTP. Serial options include no-protocol, MC, and SYSWAY.

Q4: What is the minimum 2D code resolution?
A: Minimum resolution is 0.063 mm for 2D codes and 0.082 mm for barcodes.

Q5: Is the SR-2000W protected against dust and water?
A: Yes. The housing carries an IP65 rating, so it resists dust and water jets on the line.
