Matched Impedance Coaxial Contacts

for MIL-DTL-38999

TYPICAL MATCHED IMPEDANCE

COAX SOCKET CONTACT

has socket outer contact with a captivated

pin inner contact

TYPICAL MATCHED IMPEDANCE

COAX PIN CONTACT

has pin outer contact with a captivated

socket inner contact

The matched impedance coax contact is available in size 12 It incorporates a captivated

inner contact which“snaps into”the outer contact preventing displacement or

pull-back of the inner contact in situations where the cable may be bent

Design features and benefits of the Matched Impedance:

• For use in 90 degree angle or bent cable applications

• Provides 50 ohm matched impedance resulting in low VSWR

and low insertion loss

• Frequency range for a mated pair extends to 3 GHz and beyond,

higher than other coaxial contacts previously offered

• Ideally suited for D38999 high performance and MIL-STD-1760

high band coaxial contact requirements

High Performance Size 12 and 8 Coax

50 or 75 Ohm matched
