The environmental constraints to which these connectors may be subject require special adaptation:
- Behaviour in an ionising medium with absorbed doses greater than 5.106 Gy (unit of absorbed dose: a GRAY (Gy) – 1 Gy = 102 Rad)
- Insulation resistance between the central contact and the external shielding greater than 1014 Ω.
- Extremely low shielding conduction resistance requiring a copper + stainless steel metal sandwich structure.
- Use in an atmosphere with nitric acid vapour.
- Use of cables with special insulators, double or triple braid, with an external diameter between 3 and 20 mm.
