Product Overview

The SICK CLV620-0120 is a mid-range fixed mount barcode scanner. This device reads all standard 1D code types. It works perfectly for conveyor systems and packaging lines. The scanner has a front reading field with fixed focus. You can rely on this unit for high-speed material flow tracking.

Technical Specifications

The SICK CLV620-0120 offers a reading distance from 60 mm to 365 mm. The aperture angle reaches ≤ 50 degrees. Scanning frequency ranges from 400 Hz to 1,200 Hz. Code resolution falls between 0.2 mm and 1 mm.

Key technical parameters include:

• Light Source: Visible red laser at 655 nm (Laser Class 2)

• Scanning Type: Line scanner with light spot

• Code Resolution: 0.2 mm to 1 mm

• Print Ratio Support: 2:1 to 3:1

• Number of Codes Per Scan: 1 to 20 (Standard decoder) or 1 to 6 (SMART620)

The device operates on 10 V DC to 30 V DC. Power consumption is only 4.5 W. The scanner weighs 205 g without cable. Dimensions are 61 x 66 x 38 mm.

Supported Barcode Types

The SICK CLV620-0120 reads all current 1D code types. These include Code 39, Code 128, and Code 93. It also reads Codabar, GS1-128/EAN 128, and UPC/GTIN/EAN. Interleaved 2 of 5, Pharmacode, and GS1 DataBar work too. Telepen and MSI/Plessey are also supported. The device reads up to 50 codes per reading interval. Each interval handles up to 1,500 characters.

Communication Interfaces

The SICK CLV620-0120 offers multiple communication options. The primary interface is Ethernet (TCP/IP) at 10/100 MBit/s. It supports PROFINET directly on the device. EtherNet/IP is also available. An optional external module (CDF600) adds EtherCAT support.

Serial interfaces include RS-232, RS-422, and RS-485. Baud rates range from 2,400 to 115.2 kBaud. The device also features CAN and CANopen at speeds up to 1 Mbit/s. For fieldbus integration, you can add PROFIBUS DP via the CDF600-2 module.

Connectivity and Indicators

The scanner uses two M12 cylindrical connectors. These include a 12-pin male connector and a 4-pin female connector. Both sit on a swivel connector for flexible mounting. The CLV620-0120 has 3 digital inputs and 2 digital outputs. Outputs require the optional CMC600 parameter storage module.

Optical indicators include 6 LEDs. These show Ready, Result, Laser, Data, CAN, and LNK TX status. An acoustic beeper provides audible feedback. You can switch the beeper off or assign it as a result indicator.

Installation Guidelines

Follow these steps for proper installation:

1. Mount the scanner on a stable bracket near the conveyor.

2. Adjust the reading distance between 60 mm and 365 mm based on code size.

3. Set the scanning frequency from 400 Hz to 1,200 Hz using SOPAS ET software.

4. Connect the M12 Ethernet port for data output and service access.

5. Configure the reading pulse using digital inputs or auto-pulse mode.

6. Test the scanner with your lowest contrast barcodes (PCS ≥ 60%).

The glass window must stay clean for optimal performance. Ambient light should not exceed 2,000 lx on the barcode.

Common FAQs

Q1: What is the maximum reading distance of the CLV620-0120?
A: This scanner reads codes from 60 mm to 365 mm. The exact distance depends on code resolution and print quality.

Q2: Does this scanner read 2D codes like QR codes?
A: No, the CLV620-0120 reads only 1D barcodes. For 2D codes, please consider SICK's ICR or Lector series.

Q3: Can I use this scanner on a moving conveyor?
A: Yes, the scanning frequency reaches 1,200 Hz. This speed handles high-speed conveyor applications easily.

Q4: What laser class does this device have?
A: The CLV620-0120 uses a Laser Class 2 visible red light source. It is safe for normal use with eye aversion responses.

Q5: How do I configure the scanner for my specific barcode type?
A: Use the SOPAS ET software on a PC. Connect via Ethernet or RS-232 to set code types and reading parameters.
