series 41 contacts ?arge surface area contact mating system high reliability ?losed entry?design precision machined solid copper alloy all contacts of the series 41 connector family utilize the ?arge surface area (l.s.a.) contact mating system.?the ?.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 ?losed entry?design female contacts. the ?losed 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. section a-a enlarged spring retention member large surface area contact mating surface male contact a a female contact spring retention member provides uniform retention of male contact when mated.
