WF Series Circular Connectors for HiFi Audio and Clear Video

WF Series Circular Connectors for High-Fidelity Audio and Video Systems

The WF series circular connectors are designed for low-loss signal transmission in professional and consumer audio-video (AV) systems. With gold-plated contacts, IP-rated protection, and multiple shell sizes, these connectors support applications from home theater and HiFi equipment to live stage rigs and broadcast production. The series offers a range of core sizes and pin configurations to match specific AV signal density and power requirements.

Selecting the Right WF Shell Size

The WF series covers five shell sizes, each optimized for different AV signal density and power requirements. Choose based on your panel cutout, pin count, and application environment:

• WF12: 12mm panel cutout, ideal for compact stereo audio links, headphone amplifiers, and portable recording devices.
• WF16: 16mm panel cutout, a versatile size for mid-range AV systems, supporting 2–12 pins for multi-channel surround sound and entry-level video transmission.
• WF20: 20mm panel cutout, the most popular size for professional AV, balancing space efficiency with 2–16 pin capacity for 4K video and 7.1-channel audio.
• WF24: 24mm panel cutout, designed for high-density applications like AV matrix switchers and broadcast routers, offering 2–24 pins for complex multi-signal setups.
• WF28: 28mm panel cutout, the largest size, supporting up to 24 pins and higher current for power+signal hybrid AV systems, such as LED video walls and stage lighting control.

Pin Configuration and Signal Capacity

Each WF size offers 2 to 24 pin options, tailored to AV signal needs:

• 2-4 pins: Basic stereo audio connections for home theater speakers, microphones, and consumer-grade AV receivers.
• 6-12 pins: Multi-channel surround sound (5.1/7.1) and SDI video transmission for professional studios and live events.
• 16-24 pins: High-density AV matrix systems, broadcast routers, and LED video wall controllers requiring simultaneous audio, video, and control signals.

Performance Characteristics for AV Fidelity

Gold-Plated Contacts

Gold-plated brass contacts ensure low and stable contact resistance, minimizing signal attenuation and preserving the clarity of high-fidelity audio and 4K/8K video. This helps maintain dynamic range in professional recording and playback applications.

Environmental Protection

IP40 (indoor) to IP65 (outdoor) ratings shield against dust, moisture, and accidental splashing, supporting reliable performance in both climate-controlled studios and outdoor broadcast sites.

Temperature Stability

An operating temperature range of -40°C to +105°C (industrial grade) supports consistent signal integrity in extreme environments, from winter outdoor events to summer festival stages.

Locking Mechanisms

Push-pull locking provides tool-free, one-click mating with audible confirmation, suitable for frequent setup changes in live events. Bayonet twist locks are available for industrial models, offering enhanced vibration resistance for mobile broadcast trucks and stage rigs.

Termination Options

The series supports solder, crimp, and screw termination, enabling integration with fine-gauge audio cables, thicker power cables, and PCB-mounted AV equipment.

Application Fit and Boundaries

The WF series adapts to diverse AV environments with size and performance matched to specific use cases:

• Home Theater & HiFi Systems: WF12 and WF16 sizes deliver low-loss stereo and multi-channel audio, preserving the detail of music and film soundtracks.
• Live Stage & Events: WF20 and WF24 with IP54-IP65 protection resist dust, moisture, and vibration, supporting reliable performance for stage monitors, line arrays, and LED screens.
• Broadcast & Production: WF24 and WF28 sizes support high-density SDI video and AES/EBU audio links, relevant for live sports broadcasts and studio production workflows.
• Outdoor Installations: IP65-rated WF20 and WF24 models withstand rain and dust, making them suitable for permanent outdoor speaker systems and digital signage.

For applications requiring higher pin counts, hybrid power+signal configurations, or specific locking mechanisms, confirm the exact model and configuration with our engineering team before ordering.

Buyer's Decision Checklist

To ensure the WF series connector matches your AV system, prepare the following information when inquiring:

• Required shell size (WF12, WF16, WF20, WF24, or WF28) and panel cutout dimension
• Number of pins and gender (male/female) needed
• Termination type: solder, crimp, or screw
• Environmental requirements: indoor (IP40) or outdoor (IP65) rating
• Locking preference: push-pull or bayonet twist
• Cable diameter and conductor gauge for the application
• Signal type: analog audio, digital audio (AES/EBU), SDI video, or hybrid power+signal
