MIL-DTL-38999 Circular Connectors
DEPENDABLE
MIL-DTL-38999 Series IV Connectors
• Secure breech lock coupling
• 100% scoop-proof
• Pin-to-pin mating protection helps
prevent failures
RUGGED
• Mated connectors help withstand
high-impact shock
• Rear accessory threads help provide
increased strength
• >500-mating-cycle durability
• Corrosion resistant
EMI PROTECTED
• Grounding fingers for excellent
EMI protection
• Connector is grounded when the
shells meet, even before the contacts
are engaged
EASY INSTALLATION
• Blind-mateable grounding fingers
to help provide a safer assembly
during mating
• Requires only 90° rotation to
engage and disengage
DEUTSCH DIV Series Connectors
DEUTSCH DIV Series connectors from TE Connectivity (TE) are
high-performance MIL-DTL-38999 connectors for use in high
shock, vibration and EMI environments where reliability
is essential.
Qualified to MIL-DTL-38999 specifications, DEUTSCH DIV Series
connectors are designed and built using the high-vibration
capable breech lock coupling mechanism that only requires 90°
of rotation to engage and disengage.
Special grounding fingers form a 360-degree circle just inside
the shell, acting as a shield for excellent EMI protection. The
connector is actually grounded when the shells meet, even before
the contacts engage.
Inserts are available in 8 shell sizes, with contact arrangements
meeting MIL-DTL-1560, along with additional arrangements, to
help provide flexibility in circuit configurations.
