Terminal Blocks - Accessories - Marker Strips

1. Overview

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.

2. Main Types and Functional Classification

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

3. Structure and Composition

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.

4. Key Technical Specifications

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

5. Application Fields

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.

6. Leading Manufacturers and Products

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

7. Selection Guidelines

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

8. Industry Trends Analysis

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
