I. Basic definition (7W2 layout)
Needle position: 7W2 = 5 normal signal needles + 2 coaxial RF needles (50 Ω RF contacts7W2)
Installation form: 90 ° bend foot (Right Angle / R / A), horizontal welding on the PCB board, vertical outlet line
Structure: DA D-SUB metal shell (shielding EMI) + PBT flame retardant rubber core + turning gold-plated terminal; The RF core is coaxial and can transmit high frequency signals (up to 2 GHz)
Selection distinction: male head (needle) / female head (porous); With fixed bracket / M3 screw lock; Ordinary / IP67 waterproof model
II. Core Electrical Parameters (Radio Frequency Version)
1.Signal needle: 5 A, gold-plated needle, contact impedance ≤ 15mΩ
2.RF coaxial pin: 50Ω resistance match, DC ~ 2GHz high frequency transmission, small standing wave, suitable for RF signal, high frequency testing, communication port
3. Frontal and fixed voltage: 250 V AC; Withstand voltage 750 V AC
4.Environment: -55C ~ + 105C, UL94-V0 rubber core, salt spray 12h, insertion life ≥ 1000 times
5. Locking: M3 screw lock, anti-vibration, industrial control, vehicle, equipment board universal
III. Structural features (advantages of the bent version)
1.90 ° bend insert foot: PCB horizontal installation, do not raise the device, compact chassis, high density board card preferred, to avoid the height of the space occupied by direct insertion
2. Signal + RF integration: A D-SUB interface replaces the "ordinary DB head + RF SMA head," simplifying the panel openings, reducing the wiring harness, and achieving higher equipment integration.
3. All-metal nickel-plated housing: shields against electromagnetic interference, ensuring that radio frequency signals remain unaffected. Suitable for communication, instrumentation, and monitoring/control equipment.
4. Optional: opaque / strap bracket; Plain Plate End / Sealed IP67 Waterproof Plate End (Outdoor Equipment)
IV. Typical application scenarios
5G communication board, RF test instrument, radar control board
Industrial Measurement and Control, Servo Motion Control, Robot Vision IO + High Frequency Signal Hybrid Interface
Medical equipment, military electronics, vehicle electric control, board-end interfaces for energy storage equipment
Panel PCB built-in, board horizontal output signal + RF hybrid circuit
