Hybrid D’Sub series
TW / E1
Amphenol D’Sub TW Hybrid Series permits
a mix of contacts including signal, power,
shielded, high voltage and fiber optics in the
same housing with different contacts
arrangements.
This economic series was first developed from
our military series, and has improved features:
- new contacts
- new high temperature black thermoplastic insert
- PCB configurations come preloaded with
fixed contacts and brackets.
These connectors are supplied with screw
machined contacts fixed in the insulator.
A complete range of housings are also
available for cable application.
• Commercial
• Medical
• Industrial
• Telecom
• Any application requiring
optimization of space
A full series of
arrangements
compatible with
reflow process
• Connectors according to: MIL C24308 - NFC93425 - HE507
