Technical values describe the referenced SubConn configuration. DepthLink supply options, final part numbers, dimensions, ratings and mating compatibility require confirmation with your quotation. Pressure-test values are not automatically working-depth ratings.
Applications
- Video links
- Telemetry
- RF and antenna interfaces
Configuration notes
Not suitable for open-face pressure or waterblock applications. Locking sleeves are required. Published attenuation describes a 10 m cable assembly including two bulkheads, not the connector alone. Minimum inline cable bend radius: 100 mm; keep grease off the coax interface.
