Amphenol Industrial’s explosion-proof connector series Amphe-EX™ is the only explosion-proof connector that allows the use of copper, coax and fiber optic contacts in one product. The Amphe-EX™ series complements Amphenol Star-Line EX connectors, and its physical size is a smaller than most heavy-duty, hazardous-rated connectors.
Applications include chemical manufacturing, petrochemical refineries, pharmaceutical manufacturing, land and offshore drill rigs, flour and sugar refining, aircraft fueling pods – all areas where the risk of an explosion exists.
PEI-Genesis is the only approved worldwide assembling distributor of Amphe-EX™ Circular Connectors.
Amphenol Amphe-EX™ Series Zones
The Amphenol Amphe-EX™ Series is ATEX and IECex-approved for Zone 1-rated (Europe) (IECex 60079).
The IEC has defined three areas of hazardous gas or vapor release as follows:
Zone 0, Zone 1, and Zone 2.
Zone 0:
Explosive atmosphere is continuously present.
Zone in which an explosive mixture of gas, vapor or mist is continuously present.
Zone 1:
Explosive atmosphere is often present.
Zone in which an explosive mixture of gas, vapor or mist is likely to occur during normal operations.
Zone 2:
Explosive atmosphere may be present.
Zone in which an explosive mixture of gas, vapor or mist is not likely to occur in normal operation and if it occurs, it will only exist for a short time (leaks or maintenance).
Determining a Zone
When determining a zone, four questions should be considered:
- What is emission level of gas/vapor?
(a) continuous
(b) first level emission (released during normal operation)
(c) second level emission (released during abnormal operation) - What type of openings currently exist?
(a) continuously-open
(b) normally closed
(c) weatherproof
(d) emergency open only - What is ventilation?
(a) very good
(b) good
(c) poor - What is the level of ventilation?
(a) high
(b) average
(c) weak
