How to buy crystal head to match super 5 categories 6 categories 7 categories

　　When purchasing crystal heads that match Super Category 5, Category 6, and Category 7 network cables, the following principles must be followed to ensure tranSMission performance, stability, and compatibility:

　　First, the matching principle

　　Super 5 network cable

　　Recommended match: Super 5 crystal head (CAT5e)

　　Compatibility: Category 6 crystal heads (CAT6) can be used temporarily, but it should be noted that:

　　If the wire diameter of more than 5 types is thin (24AWG), the insertion of 6 types of crystal head (suitable for 23AWG) may be loose, and it is necessary to ensure that the wire core is in close contact with the touchpoint.

　　Do not recommend long-term use: Category 6 crystal head shielding design may weaken the signal quality of Category 5 wires.

　　Category 6 network cable

　　Recommended match: Category 6 crystal head (CAT6) or Super Category 6 crystal head (CAT6A)

　　Key features:

　　Support 10Gbps transmission rate, compatible with 10 Gigabit Ethernet.

　　Select a crystal head with a shielding layer (e.g. STP) to enhance anti-interference ability.

　　Gold-plated touchpoint priority: improve conductivity and corrosion resistance, extend service life.

　　Category 7 network cable

　　Recommended match: Category 7 special crystal head (CAT7)

　　Mandatory requirements:

　　A shielded crystal head (e.g. S-FTP) must be used, and must be equipped with a Category 7 shielded network cable, socket, and patch panel.

　　Special design: Part 7 crystal head with "swallow tail clip" structure, enhanced shielding effect and wire core fixing.

　　II. Selection of Precautions

　　Shield Type Matching

　　Unshielded Network Cable (UTP): Select Unshielded Crystal Head.

　　Shielded network cable (STP/SFTP): The same type of shielded crystal head must be selected, otherwise the shielding layer will fail and the anti-interference ability will decrease.

　　contact stability

　　Shrapnel design: three-pronged reed or blade touchpoint is preferred to ensure that the wire core is in close contact with the touchpoint.

　　Gold plating thickness: Gold plating layer ≥ 3μin (microinch), which can reduce the risk of oxidation and improve signal quality.

　　Certification and Standards

　　Compliance: Select crystal heads that comply with TIA/EIA 568A/B standards to ensure line sequence compatibility.

　　Brand identity: Avoid unbranded, uncertified products, and prioritize crystal heads that are clearly labeled with categories (such as CAT5e/CAT6/CAT7).

　　III. Purchase channel suggestions

　　Official channels: brand official website or flagship store (such as JD.com, Tmall brand direct-operated store).

　　Authorized dealers: ensure genuine products and after-sales services.

　　Pit avoidance tips:

　　Be wary of low-priced unbranded products, which may use inferior plastics and copper sheets, resulting in poor contact.

　　Before purchasing in bulk, it is recommended to test samples to confirm compatibility and performance.

　　IV. Installation and testing

　　Tool preparation:

　　Mesh pliers (need to be adapted to the type of crystal head, such as Category 7 requires special crimping tools).

　　Network tester: Test connectivity and speed after installation.

　　Operation steps:

　　Stripping wire → cable (according to T568A/B standard) → cutting the wire core → inserting the crystal head → pressing wire → testing.

　　Summarize:

　　Super 5 category: choose CAT5e crystal head, you can use CAT6 temporarily.

　　Category 6: Preference is given to CAT6A with shielded gold-plated head.

　　Category 7: Must use CAT7 shielding head, full set of shielding accessories.

　　General principle: triple matching of shielding layer, wire diameter, and authentication standards to ensure network stability.
