NU25 connectors

This stainless steel bayonet lock connectors have been designed for K2 classed and non-classed nuclear applications.

A 360° shield complying with the requirements of RCC-E 2005 gives rise to a reduction effect of approximately 50 dB at 1 MHz.

Based on the NF L 54-120 standard, this new version of connector benefits from feedback of over 30 years both from sensor manufacturers and power station users.

This new design was aimed at facilitating the assembling of receptacles on sensors, simplifying the wiring of plugs and improving sealing.

The sealing of the plugs has been reinforced by an adhesive heatshrink sleeve which guarantees efficiency over time not guaranteed by a simple gland.
