3. Unique Product Competitive Advantages
Four-Channel Symmetrical Independent Winding Design
Four separate winding chambers isolated by plastic partitions eliminate magnetic interference, ensuring stable switching pull force without filter jamming.
Integrated Multi-Position Locating Frame
Square outer positioning lugs + central octagonal hole achieve dual positioning, perfectly fitting compact internal cavities of mini IR-CUT modules.
Pre-Tinned Fixed Terminals
Metal terminals are pre-fixed on the plastic skeleton, avoiding secondary wire binding and compatible with automatic soldering production lines.
High Heat Resistance Anti-Aging Plastic Frame
Special modified PBT material resists long-term heat accumulation of 24-hour running surveillance cameras, preventing skeleton warpage.
