EMC cable entry frames

EMC cable entry frames

Modern industrial process technology demands increasingly robust protection against electromagnetic interference (EMI) for electrical Measurement, Control, and Regulation (MCR) systems. Effective EMI mitigation requires special attention to two distinct interference types:

  1. Shield-Conducted Interference

    • Propagates directly from noise sources through power/signal cable shielding

    • Transmitted via cable shields to sensitive equipment

  2. Field-Coupled Interference

    • Caused by capacitive/inductive coupling from electric/magnetic fields

    • Includes all electromagnetic field-induced disturbances

EMI Protection Solutions for Industrial Applications

Field-coupled interference occurs when electromagnetic fields from disturbance sources transmit interference through cables to sensitive equipment.

An optimal solution for both interference types combines:

  • Large contact surface between cable shielding and conductive enclosure walls

  • Internal enclosure shielding

Our EMC-KEL cable entry system effectively diverts and blocks both:

  • Shield-conducted interference

  • Field-coupled interference
    Providing a cost-efficient alternative to expensive EMC cable glands.

EMC-KEL-U and EMC-KEL-E frames (based on ICOTEK's KEL-U/KEL-E products) feature:

  • Conductive surfaces for effective interference dissipation

  • Metallization for field-coupled interference diversion

  • Included conductive flat gasket between unit and metal wall
    Note: Flange surface must remain unpainted!

Key Benefits:
✓ Reliable diversion of conducted/field-coupled interference
✓ Scratch-resistant, durable surface
✓ 360° continuous contact with cable shielding
✓ Fully conductive elastomer construction
✓ High cable density capacity
✓ Excellent dissipation performance
✓ Superior EMC voltage shielding

ICOTEK Strain Relief Systems enable:

  • Fast, compliant cable assembly per EN 62444

  • Organized cable management in:

    • Machinery

    • Control cabinets

    • Enclosures

    • Cable carriers

  • Multiple mounting options:

    • DIN rail snap-on

    • C-rail

    • Screw mounting

Strain relief plates are available in multiple sizes. Use spacers for multi-layer mounting to significantly increase cable density.
