Nortek supplies two types of cables - Subconn and Impulse. In this article, we have highlighted a set of instructions on how to take care of each connector type. 

To identify which cable you have, there are two methods you can use. First, determine the instrument you are working with. All DVL's and Signatures use SubConn connectors, while AWAC, Vector, Aquadopp and Aquadopp Generation 2 use Impulse connectors. Secondly, you can identify the connector sleeve color. A red sleeve indicates a SubConn connector, while a black sleeve indicates an Impulse connector. 

SubConn connector care

• Connectors must be greased with Molykote 44 Medium before every mating
• A layer of grease corresponding to minimum 1/10 of socket depth should be applied to the female connector
• The inner edge of all sockets should be completely covered, and a thin transparent layer of grease left visible on the face of the connector
• After greasing, fully mate the male and female connector in order to secure optimal distribution of grease on pins and in sockets
• To confirm that grease has been sufficiently applied, de-mate and check for grease on every male pin. Then re-mate the connector

Impulse connector care

• Lubricate mating surfaces with 3M Silicone Lubricant or equivalent, DO NOT grease! Connectors must be lubricated on a regular basis.
• Align pins prior to mating
• Lubricate O-rings with Molykote 111 or equivalent
• Avoid nicks and cuts around contacts as these are the sealing surfaces.
• Do not pull on cable to disconnect.
• Avoid sharp bends at cable entry to connector.

Greasing connectors with not recommened products or lubricants is discouraged because some grease can act as an electrical insulator, attract contaminants, chemically degrade connector materials, be difficult to remove, and interfere with sealing mechanisms. These issues can lead to poor electrical connections, equipment malfunction, and water damage. Instead, using manufacturer-recommended lubricants or sealants ensures proper connectivity and protection without these adverse effects.

Proper connector care is vital for reliable connections, extended lifespan, and optimal performance.
