Connectors protect cables from moisture ingress even when disconnected

23-03-2015 | Intelliconnect | Connectors, Switches & EMECH

There are no shortage of waterproof connectors available to design
engineers. A great number however have to be mated to actually be waterproof
as the casing acts as the seal. In many applications this is not adequate as
connectors may have to be disconnected while in service for calibration,
repair, module exchange and connection of different ancillary equipment. In
these circumstances it is of critical importance that both the plug and jack
remain waterproof while disconnected to prevent ingress of moisture into the
connecting cable or equipment preventing loss of performance or damage.

To meet these needs, Intelliconnect (Europe) offer designers the proven
Pisces range of waterproof connectors which meet IP68 even when unmated.

The recently extended Pisces series now includes additional connector and
cable termination options suitable for most Coaxial / Triaxial / Twinaxial
waterproof connector groups. Pisces connectors are now available in SMA, TNC
and N Type cable plug options which may be connected to a wide variety of
cables including many LMR, RG, Semi-Rigid and Semi-Flexible cable types. All
plug types have matching, waterproof when disconnected, jacks to prevent
moisture ingress damaging the electronics inside the equipment housing.

The enhancements to the Pisces connector series extend the range of
potential applications to include 75ohm variants for video camera security
applications, environmental monitoring ocean buoys, traffic cameras (ANPR),
coastguard/HM customs patrol boats, personal locator beacons, defence radios
/ communication systems, environmental monitoring and water management and
vehicle tracking. Other potential applications are high quality antennas,
personal locator beacons, cochlear Implant devices, petrochemical monitoring
equipment, traffic indication systems, environmental monitoring, SCADA
(data-loggers etc.),

In addition to Intelliconnect's fast turnaround custom designed connector
service their extensive standard range includes IP67 and IP68 rated
interconnect solutions for harsh environments including N Type, SMC, SMA,
TNC, Push-Pull and ABMS (harsh environment MCX). The SSMA is a smaller
version of SMA which provides higher frequency performance. The male contact
is designed to be the same size as the cable conductor so that it can be
used as the mating pin for optimised VSWR (Voltage Standing Wave Ratio- a
measure of how efficiently radio-frequency power is transmitted from a power
source, through a transmission line, into a load).
