Key Features & Advantages

Space-Efficient Design

The miniature form factor enables higher port density in crowded equipment racks. You gain maximum channel capacity without sacrificing mechanical security. The compact profile fits tight installation spaces where standard connectors cannot.

Superior Material Construction

Gold-plated center contacts ensure excellent conductivity and corrosion resistance. Nickel-plated bronze outer conductor provides durability in demanding environments. PTFE dielectric maintains low-loss signal integrity across the entire frequency spectrum.

Reliable Bayonet Locking Mechanism

The proven bayonet coupling prevents accidental disconnection in high-vibration applications. You secure connections quickly with quarter-turn locking action. This mechanical stability surpasses push-on alternatives in professional installations.

Exceptional Electrical Performance

With VSWR ≤1.3 and 750V dielectric withstanding voltage, signal reflections remain minimal. The 75Ω impedance matches standard broadcast and telecom cable systems perfectly. You achieve clean signal transmission essential for high-definition video and digital communications.

Quality Assurance Process

SIPU implements comprehensive quality control for every.

Each production batch undergoes insulation withstanding voltage testing using specialized equipment to verify 750V dielectric strength and ≥5,000MΩ insulation resistance.

Plating quality inspection monitors coating thickness and adhesion strength across all batches. RoHS environmental compliance testing ensures regulatory conformance. Dimensional accuracy verification guarantees perfect intermateability with industry-standard interfaces.

The 500-cycle mating durability test confirms mechanical reliability throughout the connector's service life. These rigorous procedures reflect SIPU's ISO 9001 certified quality management system and 25+ years of RF manufacturing expertise.

Application Scenarios

Telecommunications Infrastructure

Ideal for DS3/DS4 digital cross-connect systems requiring thousands of secure terminations. The compact design maximizes port density in central office equipment racks. You benefit from vibration-resistant connections in switching environments.

Professional Broadcast Systems

Perfect for HD/4K video routing switchers and patch panels where standard BNCs consume excessive space. The 75Ω impedance matches broadcast cable standards precisely. High-definition signal transmission remains artifact-free across uncompressed video feeds.

Test & Measurement Equipment

Suits high-density RF testing systems where space constraints demand miniaturized interconnects. The reliable locking mechanism prevents signal interruptions during equipment handling. You achieve consistent measurement accuracy in laboratory environments.

Industrial Electronics

Serves compact RF signal processing applications requiring secure mechanical mating. The wide temperature range (-65℃ to +125℃) handles harsh industrial conditions. Silicon rubber sealing protects against environmental contamination.
