HN series coaxial connectors

HN series high reliability coaxial connectors ensure the transmission of data signals from security sensors in environments subject to nuclear radiation.

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 Ohms.

- 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.
