1. Product Introduction
Single Core BNC Cable is a coaxial cable with a single center conductor + shielding structure, equipped with a BNC (Bayonet Neill-Concelman) connector, mainly used for radio frequency (RF) signal transmission. The BNC interface adopts a bayonet locking design, which is stable and suitable for high-frequency signal transmission. It is commonly used in video surveillance, test instruments, broadcast channels and other fields.
2. Main application areas
Video surveillance system: connection between CCTV camera and DVR/NVR
Broadcasting and television equipment: camera, switcher, SDI signal transmission
Test and measurement instruments: probe connection of oscilloscope and spectrum analyzer
RF communication: short-distance RF signal transmission (such as antenna feeder)
Medical equipment: ultrasound instrument, endoscope video signal transmission
Industrial automation: video surveillance interface between PLC and HMI
3. Purchase suggestions
1. Impedance matching:
Select 75Ω for video transmission, and confirm the impedance (50Ω/75Ω) for RF applications.
2. Shielding level:
Double-layer shielding (aluminum foil + braided mesh) is selected for high-interference environments, and single-layer shielding is sufficient for ordinary scenarios.
3. Cable length:
Signal attenuation increases with length. It is recommended that video transmission be ≤30m (1080P) or ≤15m (4K).
4. Conductor material:
Oxygen-free copper (OFC) has better conductivity than copper-clad steel, but the cost is higher.
5. Connector plating:
Gold-plated BNC heads are more resistant to oxidation, and nickel-plated ones are more cost-effective.
4. Precautions for safe use
Avoid excessive bending: The minimum bending radius is ≥5 times the wire diameter to prevent damage to the shielding layer.
Anti-tension damage: Fix the cable during installation to prevent the connector from being subjected to tension.
Impedance matching: Ensure that the impedance of the devices at both ends is consistent (such as a 75Ω camera with a 75Ω cable).
Environmental protection: Waterproof BNC heads must be selected for outdoor use to avoid moisture corrosion.
Regular inspection: Check for connector oxidation or wire aging after long-term use.
5. FAQ
Q1: How far can a single-core BNC cable be transmitted?
A: It depends on the signal type:
- Analog video (CVBS): ≤100m (with amplifier)
- High-definition video (HD-SDI): ≤100m (1080P)
- RF signal: According to frequency attenuation, usually ≤50m (need to add amplifier).
Q2: Can 50Ω and 75Ω BNC cables be mixed?
A: Not recommended! Impedance mismatch will cause signal reflection and loss.
Q3: How to distinguish high-quality BNC heads?
A: Features of high-quality BNC heads:
- Uniform plating (gold/nickel plating)
- Good elasticity of the buckle, smooth plugging and unplugging
- The shell is made of metal (not plastic).
Q4: Can it be used for PoE power supply?
A: No! BNC coaxial cable only transmits signals and requires an additional power cable.
Q5: What is the difference with dual-core BNC cable?
A: Single-core only transmits one signal, dual-core can transmit two signals (such as audio + video), but the shielding performance is more complicated.
6. Summary
Single Core BNC Cable is the core connection line in the field of video surveillance, broadcasting, and test instruments. Its 75Ω impedance design and double-layer shielding can ensure stable transmission of high-frequency signals. When purchasing, you need to pay attention to impedance matching, shielding level and cable length. High-quality products can significantly reduce the risk of signal attenuation and interference. Proper use and maintenance can extend the life of the cable, which is suitable for scenes that require high-reliability signal transmission.
99.9% oxygen free copper material, copper core, non flammable and safer to use. The outer skin is made of brand new PVC material, which is soft, durable, effectively oxidized, odorless, safe to use, and can be purchased and used with confidence.
Using environmentally friendly new wire, the outer layer is tough and resistant to pulling, bending and not easily broken. The internal and external materials are flame retardant and not easy to burn, so you can use it with confidence!
High-quality flame-retardant materials: polymer materials have the advantages of flame retardancy and high temperature resistance; phosphor bronze gold-plated/tin-plated, with the advantages of wear resistance and corrosion resistance.
High-tech anti-oxidation technology: improve the anti-oxidation and anti-corrosion capabilities, and maintain the characteristics of the metal surface.
