Rack and panel cylindrical connectors
rnJ
description
applications
The RNJ series rack and panel
connectors are qualified for the
requirements of the standard
DAT C 5935 x 0005 HE308 21,
25, 26 & 27T models.
They are used to connect electrical
and optical devices between a
moving unit (rack) and a fixed
unit (panel) without any coupling /
uncoupling device. This function is
ensured by a system of moving and
the fixed units.
The connectors are built to allow
for design tolerances (up to the
limits shown in figure 1) during
the mating of the connectors and the
final locking of the moving
and fixed units.
These connectors are derived
from the LJT series and meet or
exceed the MIL-DTL-38999 Series I
requirements.
Main characteristics
•
EMI shielding
•
Shells are grounded before contact mating
•
Lightweight space saving design
•
Durability:
500 cycles
•
Moisture resistance:
in addition to interfacial seal, main joint souffler and rear gasket on the plug are set up
for moisture sealing between connector halves
• olive drab cadmium over nickel plating on aluminium shell (withstands 500 hours
of salt spray exposure) or electroless nickel
• Free cadmium version also available.
•
Corrosion resistance:
•
8 shell sizes from 11 to 25
•
Contact protection:
• 100% scoop-proof. The design prevents bent pins and a short circuit occuring
during mating.
• Between 1 and 128 contacts in accordance with Mil-C-39029 standard
• Crimp contacts sizes 22D, 20, 16, 12, 8, 4, 00.
• PCB contacts sizes 22D & 20 (size 16, 12, 8, please consult Amphenol)
• Wire-wrap contacts sizes 22D & 20
• optical termini (PoM series) in accordance with Mil-T-29504 standard
supplied without rear accessories. Design provides serrations on rear threads of shells.
Compatible with some M 85049 rear accessories for MIL-DTL-38999 I connectors.
