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 18 different contacts
arrangements.
This economic series was fist 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 which are fixed in the insulator.
Acomplete range of housings are also
available for cable application.
A full range of
arrangements
compatible with
reflow process
• Commercial
• Medical
• Industrial
• Telecom
• Any application requiring
optimization of space
