MIL-DTL 24643/75 Serial Bus
Usage—Marine Serial-Bus RS 232/422/485 Systems
Champlain Cable has a long history of success in the development and manufacture of data communication cables. We are the first supplier to be qualified by the US Naval Sea Systems Command (NAVSEA) for supply of this M24643/75 12.5-pair cable, and are working on the next generation 25-pair construction variant. With over 10 years of various first-QPL approvals totaling over 30 million feet of data cables installed on Naval vessels, no one else comes close. Dataclear® is the brand you can count on for Reliability, Service and Price.
Dataclear® Marine /75 cables are Low Smoke Halogen Free (LSHF) Serial-Bus Data Communications cables to serve the shipboard market. Dataclear® Marine /75 provides two major solutions for shipboard communications:
- Replacement of halogenated insulations (PVC, Fluoropolymers) in confined shipboard compartments, thereby eliminating a major source of halogenated toxic and corrosive gases in the event of fire.
- Maintains exceptional data communication capabilities in accordance with commercial serial bus protocol standards.
- High Temperature Rating: 105°C
- Low Temperature Rating: -40°C
- Voltage Rating: 300V
