Product Overview of the SICK CLV621-1120 Fixed Mount Scanner

The SICK CLV621-1120 provides dependable barcode reading for medium distance applications. This scanner uses a visible red laser with 655nm wavelength. The raster sensor type creates multiple scan lines for better coverage. Fixed focus optics keep the reading zone stable and predictable.

This long range version reads codes from 60mm up to 730mm away. It suits conveyor systems with varying package sizes. The laser class 2 rating ensures safe operation in industrial environments. Users can mount this scanner on packaging lines, sorting systems, and warehouses.

The SICK CLV621-1120 works well for logistics and material handling. Its compact aluminum housing fits into tight spaces easily. The IP65 rating protects against dust and water spray. This scanner delivers consistent reading for standard density 1D codes.

Interface and Communication Options

The SICK CLV621-1120 provides comprehensive communication interfaces. The primary interface is Ethernet with TCP/IP protocol. Data transmission runs at 10 or 100 MBit/s speeds. PROFINET support comes standard on this model with single port.

EtherNet/IP is also available for factory automation networks. The serial interface supports RS-232, RS-422, and RS-485 protocols. Baud rates range from 2,400 to 115.2 kBaud. The AUX port runs at 57.6 kBaud for RS-232 connections.

CAN and CANopen interfaces are built into the CLV621-1120. For PROFIBUS DP, an optional CDF600-2 external module is needed. EtherCAT is also available via the CDF600 module. Three digital inputs and two digital outputs expand connectivity options.

Readable Code Types and Performance

The SICK CLV621-1120 reads all major 1D code types. Supported codes include Code 39, Code 128, and Code 93. It also reads Codabar, GS1-128, and UPC/EAN codes. Interleaved 2 of 5, Pharmacode, and GS1 DataBar work well.

Telepen and MSI/Plessey codes are also supported. The standard decoder reads 1 to 20 codes per scan. The SMART620 decoder reads 1 to 6 codes per scan. Each reading interval captures up to 50 codes automatically.

The scanner handles up to 1,500 characters per reading interval. For CAN multiplexer operation, this limit is 500 characters. Multiple reading settings range from 1 to 99 repeats. The raster scanning pattern improves reading on tilted or damaged labels.

Installation Guide for the CLV621-1120

Follow these steps to install the SICK CLV621-1120 correctly.

1. Mount the scanner on a stable bracket near the reading zone.

2. Position the front window facing the incoming barcode labels.

3. Connect the M12 Ethernet cable to the 12-pin male connector.

4. Connect the 10-30V DC power supply to the 4-pin female connector.

5. Adjust the mounting distance between 60mm and 730mm.

6. Power on the unit and check the six LED indicators.

7. Use SOPAS ET software to configure reading parameters.

8. Set the scanning frequency between 400 Hz and 1,200 Hz.

9. Test with sample barcodes to verify read rates.

10. Secure all cables with strain relief where needed.

The fixed focus does not require field adjustment. Keep the glass window clean for optimal performance. Avoid mounting near strong ambient light sources above 2,000 lx.

Frequently Asked Questions (FAQ)

1. What is the difference between CLV621-1120 and CLV650-6120?
The CLV621-1120 is a long range version with fixed focus and raster scanning. The CLV650-6120 has auto focus and an oscillating mirror. Choose CLV621-1120 for simpler, cost-effective applications.

2. Does the SICK CLV621-1120 require a separate power supply?
No, this scanner accepts 10-30V DC directly from your control system. The power consumption is only 4.5 watts, which is very low.

3. Can this scanner read barcodes on curved surfaces?
Yes, the raster scanning pattern helps read curved or uneven surfaces. The eight scan lines cover a larger area than single line scanners.

4. What is the maximum number of codes per reading interval?
The CLV621-1120 captures 1 to 50 codes per reading interval. The auto-discriminating function identifies different code types automatically.

5. How do I know if the scanner is reading correctly?
The CLV621-1120 has six LEDs for status monitoring. These show Ready, Result, Laser, Data, CAN, and LNK TX conditions. The beeper can also indicate successful reads.
