Locking sleeves are not necessary for the functionality of the SC connectors. However, some customers prefer the assurance that the connectors will not become disengaged by pulling on a cable.Locking sleeves are available in several different materials: Delrin, Aluminum 6061, and Stainless Steel 303. We manufacture our own locking sleeves on a Mori Seiki turning centre and so we can easily make them with other materials specified by the customer.
Standard locking sleeves are available with the traditional snap ring groove. They are very convenient for adding a locking sleeve after a bulkhead has been installed, or anytime on a cable assembly.
We have snap rings made from Stainless Steel 302, and also Aluminum 6061 (mostly for use with aluminum bulkheads). Aluminum snap rings are much better in contact with aluminium bulkheads for galvanic corrosion reasons. Please see the Technical Notes page for more information about galvanic corrosion. Locking sleeves are also available with a shoulder instead of a snap ring.
