SERIES 41 CONTACTS
“LARGE SURFACE AREA CONTACT MATING SYSTEM”
HIGH RELIABILITY “CLOSED ENTRY” DESIGN
PRECISION MACHINED SOLID COPPER ALLOY
All contacts of the Series 41 connector family
utilize the “Large Surface Area (L.S.A.) Contact
Mating System.” The “L.S.A. Contact Mating
System” insures the lowest level of contact resis-
tance during mechanical endurance tests of 1000
coupling cycles or more. Contact insertion/with-
drawal forces remain substantially the same dur-
ing the life of the connector.
The Series 41 connectors use only “Closed
Entry” design female contacts. The “Closed Entry”
design prevents probe damage to the female con-
tacts, and will not allow the female contact to
accept misaligned or bent male contacts.
All Series 41 contacts are precision machined
from solid copper alloy barstock. They are
durable, smooth in construction, and have greater
amperage capacities than hollow, sheet metal
style contacts.
The Series 41 contact, having a large contact
surface area, produces less heat at the contact
surface, thereby permitting the connector to oper-
ate at high amperage levels continuously, and still
maintain lower connector temperatures.
