Component Specifications

Definition
A marking strip or label holder is a specialized component designed for terminal block assemblies in electrical systems. It serves as a mounting and protective structure for labels or markings that identify individual terminals, circuits, or functions. Typically made from durable, non-conductive materials, it ensures legibility and permanence of identification in industrial environments, facilitating correct installation, troubleshooting, and safety compliance by preventing wiring errors.
Working Principle
The marking strip/label holder operates by providing a secure, visible platform for labels adjacent to terminal blocks. Labels are inserted or attached to the strip, which is then mounted parallel to the terminal block. This allows technicians to quickly reference circuit information during wiring, maintenance, or inspection, reducing errors and improving efficiency. The design often includes features like slots, clips, or adhesive backing for easy label application and replacement.
Materials
Common materials include polyamide (PA), polycarbonate (PC), or ABS plastic for insulation and durability; some variants use metal (e.g., aluminum) with insulating coatings. Materials are selected for flame retardancy (e.g., UL 94 V-0 rated), chemical resistance, and temperature stability (typically -40°C to +120°C).
Technical Parameters
  • Color White, gray, or yellow for high visibility
  • Width 5mm to 20mm
  • Height 2mm to 10mm
  • Length 50mm to 1000mm (customizable)
  • Mounting Type Snap-on, adhesive, or screw-mounted
