NF07 shielded – Circular audio miniature connectors

7 pole series with enhanced shielding and gold plated spring-loaded contacts

NF07 Series

Our well-proven 7-pole circular audio miniature connectors NF07 are especially designed for communication engineering. They provide high reliability under extreme ambient conditions. The present catalogue describes the watertight connectors with a bayonet groove, covering a wide temperature range. The modular design provides many combinations allowing to suit your particular requirements.

Features

NF07: All shells consist of stainless steel and non magnetic materials.
High degree of protection: Plugs and receptacles sealed to IP68 even when not mated
Spring-loaded contacts: Hard gold plated with self-cleaning faces. Resistant to shock and vibration.
Polarization, Bayonet: The NF series feature a variety of connector orientations. 4 colour-coded bayonet latch positions are available.
EMP shielding: Excellent attenuation characteristics with regard to electromagnetic influences, RF influences and pulse repetition frequencies
