Marker strips (also known as terminal markers or identification strips) are essential components in electrical systems for labeling and organizing terminal blocks. These accessories provide visual identification of connections through alphanumeric codes, color codes, or graphic symbols. Their importance in modern technology lies in enhancing system maintainability, reducing wiring errors, and improving safety in complex electrical installations.
| Type | Functional Features | Application Examples |
|---|---|---|
| Printed Marker Strips | Laser-printable materials with high-resolution text | Custom labeling in PLC control cabinets |
| Pre-printed Number Strips | Sequential numbering (01-99) with UV resistance | Standardized industrial control panels |
| Color-coded Strips | Multi-color bands for circuit group identification | Power distribution systems |
| Rotary Marker Discs | Adjustable 360 rotating labeling system | High-density terminal blocks in automation |
| Thermal Transfer Strips | Heat-resistant marking for harsh environments | Automotive manufacturing lines |
Typical marker strips consist of three primary components: 1. Base material (usually flame-retardant polypropylene or polycarbonate) 2. Marking layer (ink-receptive coating for printing) 3. Fixing mechanism (snap-on clips or adhesive backing) Standard dimensions range from 4.8mm to 15mm width with thickness of 0.8-1.2mm. The surface features anti-glare texture for improved readability.
| Parameter | Typical Value | Importance |
|---|---|---|
| Operating Temperature | -40 C to +120 C | Determines environmental suitability |
| Voltage Resistance | 500V AC/DC | Safety insulation level |
| Material Flame Class | UL94 V-0 | Fire safety compliance |
| Marking Durability | 10+ years legibility | System maintenance reliability |
| Mechanical Lifespan | 5000+ insertion cycles | Cost-effectiveness in dynamic systems |
Major application areas include: - Industrial automation systems - Power distribution equipment - Telecommunication infrastructure - Transportation control systems - Building management installations
Typical equipment examples: PLC control cabinets, switchgear panels, railway signaling systems, HVAC controllers, and renewable energy inverters.
| Manufacturer | Key Product Series | Technical Highlights |
|---|---|---|
| Phoenix Contact | MKDS series | Modular design with tool-less marking |
| Weidm ller | ID-SL series | Color-coded strips with tactile feedback |
| TE Connectivity | AMPTRAC series | High-temperature resistant (150 C) |
| WAGO | 234 series | Vibration-proof locking mechanism |
| OMRON | V6-TB series | Anti-reflective surface coating |
Key selection factors: 1. Environmental conditions (temperature, humidity, UV exposure) 2. Terminal block pitch compatibility (5.08mm, 7.62mm, etc.) 3. Marking method requirements (pre-printed vs. on-site printing) 4. Flame retardancy level (UL, IEC standards) 5. Color coding system (standardized industry schemes) 6. Mechanical durability requirements
Current development trends include: - Miniaturization for compact electronics packaging - Integration of RFID chips for smart identification - Adoption of eco-friendly materials (halogen-free polymers) - Development of anti-counterfeit marking technologies - Standardization of global marking systems (IEC 60445) - Enhanced resistance to chemical corrosion in industrial environments
