Additional information

*All frequency and attenuation values are based on a 10 meter cable assembly test including 2 bulkhead connectors (75 ohm).

SubConn® Coax connectors are dry mate only, and cannot take open face pressure.
Locking sleeves are required.
No greasing in the actual coax part.

3D files 

Please note that our 3D files are not 100 p.c. dimensionally stable due to the fact that a SubConn® connector is mainly made from rubber which changes tolerances during curing.

If a 3D file is needed for tolerance issues, please contact MacArtney for more information.
