GENERAL ORDERING INFORMATION
Amphenol Subminiature Cylindricals, which feature
rear removable contacts, are normally supplied with
a full complement of power contacts, separately
packaged. Coax, twinax and triax contacts are
ordered by part number as referenced in the part
number charts on the fol lowing pages of this
catalog, and are substituted for the power contacts
at the time of the cable or equipment assembly. If
the application is for coax, twinax or triax contacts
only, the connector may be ordered less contacts
and no power contacts will be supplied.
Subminiature Cylindrical Connector
Overview
Amphenol
shielded contacts for high performance interconnection applications. The Subminia-
ture family is built around MIL-DTL-38999 specifications, with Mil-approved and
proprietary styles offered. Normal operating voltage for Subminiatures with power
contacts only is up to 900 VAC (RMS) at sea level.
Subminiature Cylindricals offer these features for contact termination flexibility:

Widest selection of insert arrangements that can incorporate:
Wide selection of connector shell styles and sizes
Scoop-Proof recessed design in LJT-R, TV-R and SJT-R connectors provide protection for
contacts
Standard power contacts are crimp rear release, qualified to SAE AS39029
Coax, Twinax, and Triax contacts employ the same retention system as power contacts,
simplifying user substitution
