Honeywell Analytics product testing uses >65% braid with foil (around the bundle); twisted pair; stranded 24 AWG
(minimum wiring for all qualification and certification testing.)

Connectors

All qualification and certification of Honeywell Analytics 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.
In order to adhere to EMC, all external cables need to be installed in either metal ducts or zipper tubes that
have both ends connected to ground.
All Ethernet cables need to be shielded cables.

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 (no greater than three inches).
For multiconductor connector terminations, only 360° shells should be used.
