It is not compatible with the 21128 Velocity Transducer Housing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I cut the 84661-20 to a shorter length?\u003c\/strong\u003e\u003cbr\u003e\nA: No. The terminal lugs and armored transition are factory-terminated. Cutting the cable will compromise the shield integrity and moisture resistance. For shorter lengths, order the appropriate pre-terminated cable (e.g., 84661-03 for 3 ft, 84661-06 for 6 ft).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum cable length available?\u003c\/strong\u003e\u003cbr\u003e\nA: The 84661 series is available in lengths from 3 ft (0.9 m) to 96 ft (29 m). Standard lengths include 6, 8, 10, 12, 15, 17, 20, 25, 30, 33, 50, and 99 ft. For the 84661-20, the maximum recommended length with HTVS is 305 meters (1000 ft).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Does the armor need to be grounded?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes. The armor should be grounded to the monitor rack or junction box common. However, ensure it does not create a ground loop with the internal shield drain wire. Ground the shield and armor at the same point (monitoring system end).\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between 84661-20 and 9571-series cables?\u003c\/strong\u003e\u003cbr\u003e\nA: The 84661 series features integrated armor and moisture-resistant connectors. The 9571 series may have different connector types or armor configurations.
