Fast & secure connections.

Cliff Electronics offer a wide range of Single-Pole Spring Terminals which provide simple, fast and reliable connection for a wide range of applications.

Dan Walker, General Sales Manager of Cliff Electronics, comments, “Single-pole spring terminals are used in a huge number of applications where fast, and often repeated, connections have to be made quickly and reliably. We can supply a range of mounting options to allow system designers and panel builders to find the best fit for their needs.”

Cliff Single-Pole Spring Terminals may be designed into professional and consumer audio systems, test and measurement instruments, power supplies, industrial equipment and pyrotechnic installations. Terminal spindles and mounting hardware are manufactured from high quality solid brass and nickel-plated. Plastic parts are moulded from tough glass reinforced nylon or polypropylene and mounting hardware is normally supplied unassembled

Three models are available featuring a spring in the top of the binding post for quick release and all are rated at 48V, 1A. The SPT1 has an M3 thread fitting and the SPT2 is mounted by a short M4 threaded stud and both are available in red or black. The SPT3 type features a long M4 thread fitting and may be ordered in red, black, blue, green, white and yellow.

Fibre-optic connectors.

Cliff Electronics have introduced a new addition to their market leading FeedThrough connector range. The MTP®/MTO (multi-fibre push on) FT connector allows fast and reliable through-panel connection of standard 12-72 multimode optical fibre cables.

John Hall, Managing Director of Cliff Electronics, comments, “The latest data processing technologies require the fastest transfer speeds and interconnects that can be relied on for trouble-free operation. Our new fibre-optic FeedThrough connector gives system builders an ideal solution for control and patch panel assembly and may be mounted on rack panels alongside other connectors from our wide FT range.”

Demand for MTP®/MTO connectivity is being driven by the development of 40G and 100G transceivers with MPO ports commonly used for data transmission over short distances to connect ports in switches in data centres, and to connect multimode transceivers added to existing networks to other 10G host equipment such as routers, switchers, servers and storage.

To ensure reliable connectivity the connector body is made from black nickel-plated die-cast metal and the insert made from ABS/PC rated to UL94-VO, and features a restraining clamp for secure cable connection. For system security a dust cover is available for when the connector is not in use.

The standard range of FeedThrough connectors from Cliff mount into an industry standard XLR, 23mm, cutout allowing 16 connectors, from a wide range of variants, to be conveniently mounted on 19” rack panels which Cliff can supply pre-assembled. Applications include audio, broadcast, AV and communications installations, medical, education and research and industrial control.

The recently introduced space saving DualSLIM FeedThrough connector series is just 19mm wide allowing 20 connectors to be assembled on a 19” rack panel. In addition to the applications above the DualSLIM is commonly used for NUC computers and mini-PCs, such as Raspberry Pi.

A versatile USB-C male - female connecting cable which supports Power Delivery (PD) charging at 60 watts (20v/at3A), USB 3.1 (Gen 1) 5Gb/s data transfer speeds has neen introcuced by Cliff Electronics. This may be used as a video cable for 5k@60Hz video output (Thunderbolt 3) and for audio transmission.

When used in a system equipped with Cliff FeedThrough connectors, both the XLR and SLIM versions, the cable can be used to connect to a monitor in the same way as existing HDMI and VGA FeedThrough connector versions. Cable lengths available include 0.3, 0.5, 0.75, 1, 1.5 and 2m

John Hall, Managing Director of Cliff Electronics, comments, “USBC ports are now appearing on many new devices including monitors, laptops and flash drives, and 25 % of new cars are predicted to have them by 2025. Major mobile phone manufacturers are now designing USBC connectors into their latest models enabling high speed charging and a one cable solution for charging.”

The new Cliff USB-C cables can be used with a wide range of Cliff USBC XLR and DualSLIMS footprint female to Male FeedThrough connectors, available in metal or plastic and with many assembly options.
