Microminiature Connectors
Filter-TMDM
With an increasing number of MDM connec-
Features
tors being used in avionics and military equip-
ment and with increasing emphasis being put
on EMI, RFI and EMP shielding, Cannon have
developed a range of filter connectors to suit
most applications.
•
Transverse monolith filter for EMI and RFI
shielding.
•
•
•
•
Rugged aluminum one piece shell.
Silicone interfacial environmental seal.
Glass filled diallyl phthalate insulator.
A variety of filter types for each pin.
The TMDM receptacle accommodates from 8
to 37 sizes, 24 AWG socket contacts on 1,27
(.050) centres and mates with the standard
MDM plugs.
