Industrial Code Reader Cable Solutions: Custom M12, RJ45, D-Sub, USB and I/O Cable Assemblies
They are commonly used to read barcodes, QR codes, Data Matrix codes, product labels, and traceability information during the production process.
However, stable code reading does not only depend on the code reader itself. The cable assembly also plays an important role. A code reader cable may need to support power supply, data communication, trigger signals, I/O control signals, or mixed signal transmission.
If the cable connection is unstable, the system may experience reading failures, communication errors, inaccurate triggering, signal loss, or unexpected downtime.
That is why choosing the right industrial code reader cable is important for reliable automation system operation.
What Is an Industrial Code Reader Cable?
An industrial code reader cable is a cable assembly used to connect barcode readers, fixed-mount scanners, vision sensors, or code reading devices to PLCs, I/O modules, controllers, power supplies, industrial networks, or external devices.
Depending on the equipment interface and application requirements, code reader cables may use different connector types, including:
2. RJ45 industrial Ethernet connectors
3. D-Sub 15-pin or 25-pin connectors
4. USB connectors
5. Terminal block connectors
6. Open-end wires
7. Multi-interface custom cable assemblies
ADAMICU provides customized cable assemblies for industrial code readers, barcode scanners, vision sensors, and automation equipment. Based on customer drawings, samples, or interface requirements, we can support different connector combinations and wiring solutions.
1. M12 Code Reader Cables
M12 connectors are widely used in industrial automation because of their threaded locking structure, compact size, stable contact performance, and resistance to vibration.
M12 code reader cables can be used for power supply, I/O signals, trigger signals, or industrial communication. For industrial sites that require secure locking and long-term stable operation, M12 connectors are a common and reliable choice.
2. RJ45 Industrial Ethernet Code Reader Cables
Many industrial code readers use Ethernet communication to transmit reading results, image data, or device status information. RJ45 code reader cables are commonly used to connect code readers with switches, PLCs, industrial PCs, or host systems.
In industrial environments, shielded RJ45 cables are often required to reduce electromagnetic interference from motors, conveyors, robots, and power equipment.
3. D-Sub Code Reader Cable Assemblies
D-Sub connectors are commonly used for multi-pin signal transmission, control signals, and equipment interface connections. Common options include D-Sub 15-pin and D-Sub 25-pin connectors.
D-Sub code reader cables can be used to connect code readers with controllers, PLCs, I/O modules, or other industrial equipment. For applications requiring multiple signal lines in one interface, D-Sub cable assemblies offer good integration flexibility.
4. USB Code Reader Cables
Some code readers or scanner devices use USB interfaces for communication, configuration, or data transmission. USB code reader cables are suitable for short-distance communication, device setup, and specific system connections.
For industrial applications, USB cables should also be evaluated based on connection stability, cable length, jacket material, and interference resistance.
5. Terminal Block and Open-End I/O Cable Assemblies
Many code readers need to work together with sensors, PLCs, alarms, lighting systems, reject mechanisms, or external trigger devices. In these cases, terminal block or open-end wiring solutions provide greater wiring flexibility.
Terminal block and open-end code reader cable assemblies can be customized according to customer wiring definitions. They are commonly used for trigger input, signal output, power connection, and I/O control.
6. Multi-Interface Code Reader Cable Assemblies
In real industrial projects, code reader cables often combine several interfaces in one assembly. Common examples include:
✅ D-Sub + RJ45 + terminal block
✅ D-Sub + USB + I/O wires
✅ M12 + RJ45 + open-end wires
✅ M12 + D-Sub + terminal wires
✅ RJ45 + power cable + trigger cable
Multi-interface cable assemblies can reduce on-site wiring complexity, improve installation efficiency, and make equipment integration easier for automation equipment manufacturers and system integrators.
Why Do Code Reader Cables Need Customization?
Different code reader brands and models may have different interface definitions. Even when the connector appearance looks similar, the pin assignment, power supply method, trigger signal, communication method, and cable length may be different.
Custom code reader cable assemblies can be designed according to actual equipment requirements, including:
• Connector type
• Cable length
• Pin assignment
• Number of conductors
• Shielding structure
• Jacket material
• Terminal block or open-end wiring
• Bending, oil resistance, waterproof, or drag chain requirements
A suitable customized cable solution can reduce wiring mistakes, improve installation efficiency, and support stable equipment operation.
