About Detoronics Connectors
Detoronics is a respected manufacturer of hermetic and environmental connectors for military, aerospace, and industrial applications. The DT07H-14-18PN is a circular connector featuring:
-
Threaded coupling for secure, vibration-resistant connection
-
Shell size 14 with 18 pins (arrangement per MIL-spec standards)
-
Pins typically gold-plated for corrosion resistance and low contact resistance
-
Environmental sealing when mated with appropriate cable connector
This connector type is ideal for vacuum applications where reliable, disconnectable connections are required.
