The C3 Unshielded Keystone Jack is an unshielded 6P6C modular receptacle designed for CAT3 telephone/data cabling. It features a high-strength PC (UL94-V0) housing and gold-plated phosphor bronze internal IDC contacts, maintaining stable performance within an operating temperature range of -40℃ to +70℃. The product complies with T568A/T568B standards, supports 22-24AWG (single strand/twisted) wire gauges, is compatible with solid or stranded cables, and has a withstand voltage of DC1000V / AC700VRMS (60Hz).
Advantages:
1. Extremely low contact resistance: Single wire contact resistance ≤20mΩ (maximum), ensuring minimal signal attenuation, suitable for applications sensitive to transmission quality.
2. Convenient color differentiation: Available in black and green, allowing for quick identification of different lines or functions in the cabling field, improving management efficiency.
3. Long lifespan mechanical performance: IDC stamping cycles ≥250 times, insertion/removal cycles ≥2000 times (minimum), significantly reducing maintenance and replacement frequency.
4. High performance compliant with C3 standards: The product meets the electrical and mechanical requirements of C3 standards, ensuring reliable transmission in CAT3 environments.
