Terminations suitable for EMC protection can be made using armoured cables
with our armour clamping glands. Following tests, Peppers has been informed by
ERA Technology Ltd that our glands do not significantly reduce the ability of an
enclosure to which they are attached to withstand electromagnetic interference .
We conclude that the effectiveness of a cable entry in EMC terms will generally
be limited by the cable, including the cable armour or screen. Braid screens are
not necessarily the most effective means of EMC protection. Tape armours can
give the best results. Since a Peppers cable gland makes a 360º clamp on cable
armour, it will not worsen the EMC protection of the cable entry.
The cable gland standard BS EN 50262 states that cable glands are EMC neutral. This is taken to mean that cable glands are neither affected by electro-magnetic radiation nor will cause any electro-magnetic interference in other equipment.
