Simplified Elevator Wire Harness Specification
1. What It Is
A pre-assembled wire harness for elevators, integrating multiple dedicated cables (power, signal) with terminals, CONNECTORS, and fasteners. It’s used to connect key elevator parts (control cabinets, carriages, door operators, sensors) for stable power supply and signal transmission. Designed for elevator scenarios—anti-bending, anti-interference, and flame-retardant—to avoid issues like loose connections or signal loss from frequent elevator movement.
2. Key Specs
| Technical Index | Standard Value | Elevator-Specific Use |
| Wire Gauge (AWG) | 18/20/22 (per cable in harness) | 18AWG for power cables (control cabinets); 22AWG for signal cables (sensors) |
| Voltage/Current | 450V AC / 5A-10A | 10A for power branches; 5A for signal branches |
| Temperature Range | -30℃ ~ 125℃ | Adapts to hot/cold elevator shafts and closed control cabinets |
| Insulation & Sheath | Flame-retardant XLPE/PVC (cables) + durable outer sheath (harness) | XLPE for core cables (anti-aging); outer sheath protects the whole harness from friction |
| Shielding | Aluminum foil + braid (for signal cables) | Pre-installed in the harness to block motor/interference (no wrong door movements) |
| Connector Type | Anti-misinsertion plastic housing | Matches Otis/Mitsubishi/Hitachi elevator interfaces (no installation errors) |
3. Main Advantages
- Ready-to-Use: Pre-assembled—saves 50% installation time vs. separate cables (no on-site wiring/terminaling).
- Durable: Withstands 1 million bends (lasts 8+ years, vs. 3-5 years for regular harnesses) – fits daily door openings/closing.
-Safe & Stable: Flame-retardant (self-extinguishes in 30s, meets GB 7588); pre-tested connections (no loose terminals).
4. Production Steps (Tailored for Harnesses)
- Cable Cutting: Cut multiple power/signal cables to required lengths (±0.5cm accuracy).
- Insulation Stripping: Strip 10-15mm of insulation from each cable (no conductor damage).
- Component Prep: Thread heat-shrink tubes on cable ends; trim filler wires.
- Terminal Crimping: Crimp terminals on each cable (pull test ≥6kg per terminal).
- Harness Assembly: Insert terminals into matching connectors; bundle cables with flame-retardant ties (spacing 20-30cm).
- Heat-Shrinking: Heat-shrink tubes at connections (120-150℃, no bubbles) – seals against dust/moisture.
- Organizing: Arrange the harness (bend radius ≥5cm) to fit elevator wiring slots.
- Testing & Packaging: Test for continuity/shielding; package in anti-static bags (labeled with elevator model).
5. Where to Use
| Elevator Part | Harness Purpose | Recommended Harness Type |
| Control Cabinet | Connects power modules/signals | 18AWG power + 22AWG signal cables, double shielding |
| Carriage + Door Operator | Door control/lighting/power | Flexible 20AWG cables, anti-bending outer sheath |
| Sensors (Weight/Position) | Transmits precise signals | 22AWG signal cables, single shielding |
6. FAQs
Fits all elevators? Yes—customizable for Otis/Mitsubishi/Hitachi (connector/harness length).
Why choose this over separate cables? Faster installation, fewer errors, and pre-tested stability.
Warranty? 2 years (free replacement for manufacturing defects).
