Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Multi-Wire Connectivity: Connects 11-20 wires simultaneously using spring, plug-in, and screw terminals, ensuring secure electrical connections in complex circuits.
  • Modular Organization: Features labeled slots (A-Z) for easy identification and management of wires, streamlining installation and maintenance.

Key features

  • 1. Material Technology

    • With brass contacts and polyamide housing, ensure reliable conductivity and corrosion resistance while maintaining structural integrity. The brass ensures optimal electrical performance, while polyamide provides durable insulation and resistance to environmental stress.

  • 2. Interactive Design

    • With labeled modular slots (A-Z) and flexible wire management, organize wires efficiently and reduce errors compared to unmarked connectors*. The compact, adjustable design simplifies installation and maintenance in complex setups.

  • 3. Performance Parameters

    • Supports up to 20 contacts and a 300V rating, handling high-load applications with safety and efficiency. This capacity outperforms lower-contact models for multi-wire connectivity needs.

  • 4. Scenario Solutions

    • Adaptable for home wiring, industrial systems, and automotive setups, offering universal application flexibility. The modular design accommodates diverse wire sizes and configurations, making it ideal for both small-scale and large-scale projects.

  • 5. Quick Connection Technology

    • With spring-loaded and plug-in mechanisms, achieve tool-free, rapid connections compared to traditional screw-terminal blocks*. The hybrid design (spring, plug-in, screw) balances speed and secure fastening for varied installation requirements.

Supplier's note

  1. Three Breakthroughs:

    • Labeled Slots: Alphabetical identification reduces wiring errors by 30% in complex setups.
    • Hybrid Materials: Polyamide and brass combine insulation and conductivity for safer high-current applications.
    • Multi-Connection Types: Spring, plug-in, and screw terminals cut assembly time by 25% compared to single-type connectors.

  2. Version Selection Guidance:

    • Base Model: Ideal for residential or low-complexity projects (e.g., home wiring).
    • Advanced Model: Suitable for mid-range industrial use (e.g., HVAC systems) with enhanced durability.
    • Pro Model: Designed for heavy-duty applications (e.g., automotive or robotics) requiring surge protection and IP67 sealing.

Example: The Pro version’s surge protection and IP67 rating enable safe use in outdoor or marine environments, while its fully automatic connection reduces downtime in assembly lines. Pairing with brass contacts ensures stable performance even under extreme vibrations.
