Siemon Z-MAX, MAX RJ-45 and TERA jacks

Siemon has launched the Z-MAX, MAX RJ-45 and TERA jacks, which offer reliable jack-plug connection for support of PoE applications.

The jacks feature a curved contact shape designed to improve the electrical and mechanical performance of traditional modular jacks. The products also offer high transmission performance and eliminate the risk of permanent contact deformation due to mechanical stress, as well as provide support for remote powering applications.

Unmating a jack-plug connection under a PoE load produces an arc that erodes the gold-plated jack-plug contact surfaces at the arcing location. When this erosion occurs in the area of the fully mated position, the result is an unreliable connection that can cause degraded network performance and bit error rates. Erosion on either the jack or plug contacts results in an unreliable connection. The crowned contact geometry on the jacks, however, places arcing damage, to both the plug and jack contacts, away from the fully mated position, allowing users to connect and disconnect to PoE applications with zero risk over the lifetime of the system.

The jacks have been third-party tested and certified to be in full compliance with IEC-60512-99-001 standards that specify the maximum allowable resistance change that mated connections can exhibit when subjected to insertion. They are suitable for use with Siemon’s Category 6A and 7A shielded cables that are qualified for mechanical reliability up to 75°C to ensure good heat dissipation in remote powering applications.
