The issue: getting shield continuity1.
The issue: getting shield continuityEach of the twisted pairs that make up the signal conductors running inside the ethernet cables is aluminium mylar foil shielded all along. However, a small portion of the aluminium mylar foil must be removed to untwist the pairs, crimp the contacts, insert them in the corresponding modules and place the contact modules inside the core shell. Along that very short stretch of cable with the mylar foil removed, shield continuity is interrupted. That’s exactly where the issue would arise….

Core shell as a shield2.
Core shell as a shieldThe shell at the heart of the Syntax® SGH series is indeed the core of the system. Not only it is a precision machined element housing the modules where the contacts are withheld; even more important than that is its function as an active component of the connector's shielding system.

Shield draining3.
Shield drainingAfter a small portion of the mylar foil has been removed (as described at # 1), the ethernet pairs are no longer fully shielded. For shield continuity, the drain wire of each ethernet pair is crimped onto a specific shield drain contact (a male pin) connected to a shield propagator (a female socket) inserted in the core element. For each ethernet line, there is a shield drain contact and a corresponding shield propagator.

The conductive pinsNEW DESIGN for 2022 SGH version
NEW DESIGN for 2022 SGH version
Shield propagation between the two connectors is ensured by four new and improved conductive pins. The male pins have been carefully designed and machined with springs inside to help provide optimal contact quality to the corresponding females, even in rough working conditions. The application of this new pin design results in enhanced reliability and performances of our shielding solution.

Full shield propagation5.
Full shield propagationThe Syntax® SGH connector’s outer capsule has a conductive galvanic surface. Thanks to the combined action of the shield propagating contacts and the conductive treatment on the surface of the capsule, full shield propagation is obtained from cable to cable through the mated SGH connectors. It’s as if your cables had never been interrupted!
Thanks to its conductive galvanic surface, the capsule is a double-purpose element that, in combination with the Syntax Safe Tunnels, creates an interference-free area providing full Next/Fext protection.
