Thin and flexible triax cables with LEMO connectors for camera operations
22 years old. Gear and prices may have changed since.
What the thread found
- Miniature triax cable assemblies with KINGS connectors can be supplied with alternative connector types including LEMO or FISCHER at the same price.
- LEMO and FISCHER triax connectors comply with the KINGS standard and are interchangeable in the US market.
- European FISCHER triax connectors are not compatible with US-spec KINGS or other brand connectors due to different keying.
- A solution for camera work involves mounting the main triax cable to the operator's vest using a carabiner, then running a separate miniature triax from vest to camera to reduce weight and tension on the camera.
- Very thin triax cable at 0.4mm diameter with 75-ohm impedance and flexible construction exists as an alternative for internal wiring applications.
- Standard video cable at 0.4mm can be used for triax wiring on some camera models by connecting both shield grounds, though this does not work on all camera types.
- Thin triax cables used for camera connections should not exceed 1.5 to 2 meters in length.
Depends on
- Flexibility satisfaction with miniature triax cables varies among users, with some preferring to keep coax as backup.
- Compatibility issues with LEMO receptacles on older equipment have been reported historically.
- The workaround using standard video cable with dual shield connection only works on specific camera models like Thomson 1707 and Thomson 1657.
- The 0.4mm thin cable options are primarily suitable for internal wiring rather than external camera connections.
- Availability and ongoing production of specific cable options mentioned in 2004 is unclear as of later queries.
