Press Fit Connectors
For PC Board Applications–38999 Option
Amphenol manufactures a complete series of
MIL-DTL-38999 Series I, II, and III Connectors with Press Fit
compliant pin contacts for solderless mounting on printed circuit
boards. Both pin and socket contacts are available in any MIL-
DTL-38999 Series I, II or III insert pattern having contact size 16, 20
or 22D. Available in Mil-Spec and custom shell configurations.
See section “Series III TV”, “Series II JT”, and “Series I LJT” for
MIL-DTL-38999 Circular Connectors’ inserts and shell styles and the
PCB section for Press Fit Connectors on Printed Circuit Board ap-
plications.
Benefits include:
• High speed, low cost board assembly
• Elimination of soldering thermal stress
• No cold soldered joints
• No short circuits by soldered connections
• No cleaning of excess flux
• Optional contact for piercing conformal board
coating is available
Press fit connectors accommodate boards with minimum 0.090 inch
thickness and 0.040 +/– .003 plated through holes. The insertion
force for mounting the connector on the board is 7 to 16 pounds per
contact. Refer to L-40450-207 for installation instructions. Contact
Amphenol Aerospace for ordering information.

Press Fit
Amphenol Press Fit Contact Technology
• Beryllium copper tail, heat treated to
spring hardness
• The compliant eye is a natural
2 beam spring
• The eye is oversized relative to the
plated through hole and is compressed
upon insertion
• After insertion the spring exerts a
normal force on the hole creating an
electrical path via a tight friction fit
