applications where box to box mating is required outside a
sealed enclosure such as in Line Replaceable Units. Radial
and axial float are critical in these applications in order to
ensure that any misalignment generated during manufacturing or install can be compensated for by the interconnect. Given the high cost and complexity of inside the box
electronic components, introducing the potential for water
damage or electrical failure caused by foreign object mitigation is not an option.
SV Microwave’s goal was to design a connector that provides a solution to this problem by offering a high performance interconnect that is both sealed against the environment and has the floating characteristics of a blindmate
connector. SV Microwave now offers the Sealed Floating
Blindmate connector (SFB connector).
ELECTRICAL/MECHANICAL SPECIFICATIONS OF
THE SFB CONNECTOR
The SFB connector utilizes the physical dimensions and
electrical/mechanical performance characteristics of SV’s
BMZ connector line. These are defined as:
• VSWR less than 1.3:1 at 18 GHz
• Insertion Loss less than 0.3 dB at 18 GHz
• Dielectric Withstanding Voltage = 1000 V RMS
• Axial Float = 0.06"
• Radial Float = 0.02"
• Engage/disengage forces = 12 oz (max)/2 oz (min)
The BMZ interface offers a few distinct advantages over
conventional BMA (OSP) and BMMA (OSSP) connector
interfaces. The first advantage is the use of splayed fingers
and a recessed
contact to ensure
that the connector
is fully grounded
before the male
and female con-
tacts are mated.
This is clearly
shown in the cross
sectional image of
the BMZ connec-
tor in Figure 3.
