Cabling; Connectors - Honeywell Vertex M User Manual

1.5 Cabling

At a very minimum, all cables should include a braided shield. Ideal results have been obtained
with twisted pair cabling which has a foil shield surrounding each pair plus foil and 90% braid
shielding around the bundle. In addition, ensure local electrical code requirements are met.
The following cable parameters must be considered:
Braid
Foil
Twisted Pair
Stranded Pair
Shield Termination
Note: Honeywell product testing uses >90% braid with foil (around the bundle); twisted pair;
stranded 24 AWG (minimum wiring for all qualification and certification testing.)

1.6 Connectors

All qualification and certification of Honeywell products were achieved with high quality
connectors, providing 360° shield coverage. These connectors generally had metal shells.
Failure to properly secure the connector to the equipment will result in high emission levels.
Also, poorly constructed or improperly assembled connectors can be a high source of radiated
noise and provide a path for external signals into the monitor.
Vertex M
Must have a minimum 90% coverage.
When used with braid, provides 100% coverage.
Do not use foil alone. It has a tendency to break.
Provides for cancelling of magnetic fields.
Provides the greatest surface area.
Continuation of the shield to the cabinet earth ground is most
important. For discrete wire terminations, pigtails to the
cabinet (connector) ground should be extremely short
(absolutely no greater than three inches or eight centimeters).
For multiconductor connector terminations, only 360° shielded
shells should be used.
