Connectors protect cables from moisture Ingress - even when disconnected!

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.

Intelliconnect (Europe) Ltd offers designers their market leading 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 product enhancements to the Pisces connector series extend the range of potential applications to include 75 ohm variants for video camera security applications, environmental monitoring ocean buoys, traffic cameras (ANPR), coastguard/HM customs patrol boats, personal locator beacons, military 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 renowned 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).
