DEM Manufacturing has announced that its latest range of IP67 and IP68 aluminium enclosures has now been upgraded to include enhanced EMI and RFI protection.

The new Deltron 480C and 483C ranges of aluminium enclosures now have combined IP67/IP68 ratings and EMI/RFI protection, making these enclosures ideally suitable for the most demanding electrical and environmental conditions in marine, industrial, food preparation, transportation, leisure, military and aerospace. All are certified to BS EN 60529: 1992.

When using a conductive enclosure, the EMI/RFI screening achieved can be significantly impaired with the application of a non-conductive sealing mechanism. DEM Manufacturing has designed an EMI/RFI seal which maintains conductivity between the lid and box, and is essential to eliminate high frequency radiated emissions. This therefore allows EMI and RFI screening properties to be unaffected, whilst maintaining a watertight seal of up to 1 metre for 30 minutes (IP67), and depths of up to 5 metres for 1 hour (IP68). This means the enclosure is ideal for use in high humidity, underwater applications and applications subjected to heavy spray.

All of this adds up to enclosures manufactured from high grade materials and processes to match the stringent and increasing demands of today's industry.

DEM Manufacturing offers a range of die cast aluminium enclosures: plain and coated, flanged, sealed, IP65 and IP66, with a full ‘one stop’ solution for design, engineering finishing and box build. Also offered is a selection of ABS, polycarbonate IP65 enclosures. The Deltron 480C series offers 15 standard box sizes, whilst the Deltron 483C series consists of 9 sizes of flanged boxes. Sizes range from 60mm x 55mm x 31mm to 275 x 175 x 66mm – the largest range available from a European supplier.

Deltron Components XLR Connectors

The Deltron range of XLR audio and video connectors incorporate many innovative features.
The cable mounting plugs and sockets feature robust die-cast metal back shells or plastic back shells both incorporating an anti-vibration collar. The whole product range can be fitted with a unique reusable colour coding system which enables fast identification of audio/video channels.

Deltron XLR connectors incorporate a range of universal panel mounting connectors which utilises the same panel mounting cut-out for both plugs and sockets, which makes the product range extremely versatile. The universal range of connectors is also available in a non-latching version for users who prefer the slightly faster disconnection that this type of connector allows.

The Deltron XLR range can be front or rear panel mounted and is available in nickel or black chrome shell finish, with either silver or gold plated contact options.

- Available with Silver or Gold Contacts

- Nickel or Black shell

- 3, 4 and 5 pin configuration

IP68 Cable Glands

The IP68 cable glands give a secure seal which is suitable for a variety of applications. In addition, they can be combined with reducing or multi purpose seals to give extra flexibility.
These cable glands provide IP68 protection thanks to their special design and high quality rubber seal. Robust, irreversible threads on cap nuts and glands prevent stripping under high torque and protect against vibration even under extreme conditions.

Just introduce the cable, screw tight, and the job is done! All in just the one operation, the cable is centered, fixed in place and locked against rotation. The enlarged surfaces of the cap nut permit easy pre-assembly by hand and precision mounting with the machinists wrench

14 Way Mains Distribution Unit

DEM Manufacturing has launched a new Mains Distribution Unit with 14 IEC outputs. The MDU14L builds on the broadcast-industry standard MDU12L and provides two extra outputs in the same size 1RU rack mounted case.
The power is applied to the unit via a retaining PowerCon connector and a loop-through output is provided. The mains switch controls the output array and an optional switch-guard is available to avoid unintentional switching.

The maximum total output current is 16 Amps and each individually fused IEC output can be up to 6 Amps. LED indicators show that power is available at each output.

The unit has a designation strip to provide clear output identification and the rear of the unit has an integral tie-bar to ensure proper cable strain relief
