The Low-Impedance canted coil spring is a precision elastic contact component designed to provide stable electrical grounding, electromagnetic shielding continuity, and controlled mechanical compliance within complex electronic systems. Its angled coil structure enables multiple, evenly distributed contact points, creating a consistent low-resistance path between mating surfaces.
Unlike traditional grounding clips or rigid conductive contacts, this type of canted coil spring maintains continuous electrical engagement even when exposed to vibration, tolerance variation, or thermal expansion. As part of a complete connector and interconnection solution, YFS Technology (SZ) Co., Ltd develops these springs to support reliable EMI control while simplifying mechanical design.
By combining elastic recovery with conductive performance, Low-Impedance Canted Coil Springs help engineers achieve long-term shielding integrity without increasing assembly complexity.
The angled coils create multiple simultaneous contact points, reducing localized resistance and improving grounding consistency.
Designed to maintain reliable conductivity across repeated compression cycles, minimizing signal noise caused by intermittent grounding.
Accommodates misalignment, surface variation, and mechanical movement without losing electrical continuity.
Manufactured using copper alloy, stainless steel, or specialty conductive materials with optional silver or gold plating.
Easily integrated into narrow gaps, grooves, or enclosure interfaces where traditional grounding methods are difficult to apply.
Continuous contact pressure helps prevent electromagnetic leakage by maintaining a stable conductive path across enclosure interfaces.
Eliminates the need for rigid grounding straps, screws, or multiple fasteners, simplifying system design.
Elastic contact structure prevents grounding failure caused by shock, vibration, or mechanical fatigue.
Resists oxidation and wear when combined with appropriate plating, ensuring stable impedance over time.
Spring dimensions, coil pitch, and material selection can be adjusted to match specific impedance and compression requirements.
Used between metal housings, covers, and frames to maintain shielding continuity in electronic enclosures.
Applied in base stations, antennas, and communication modules where grounding integrity is critical to signal quality.
Supports stable grounding in control units, infotainment systems, and power electronics exposed to vibration.
Used in control cabinets and industrial devices to reduce electromagnetic interference.
Helps ensure reliable grounding and shielding in high-reliability electronic assemblies.
