Fully tested standard and customised industrial imaging cables

Stemmer Imaging can supply a vast range of cables and cabling for industrial imaging applications. Components Express Inc (CEI) is a global supplier and manufacturer of high-quality flexible cabling to the imaging and vision sector, and specialises in moulded cable assemblies in both standard and custom configurations. CEI's commitment to test fully every cable its makes fits perfectly with Stemmer's philosophy of selling only fully tested cables, making CEI a valued cable partner.

As the lead cable manufacturer in the CameraLink committee, CEI tests all CameraLink cables with real image data using a camera simulator and frame grabber, and rates them for the bandwidth they can actually handle. Tests are carried out in both directions along the cable since the pair that was carrying a data signal in one direction could be carrying a clock signal in the other direction. Each tested cable is given a serial number that ensures traceability back to the test results. High-quality shielding eliminates the possibility of EMC spikes disturbing the signal on the cable.

Where extended cable lengths are required, CEI's exclusive Bitmaxx technology utilises 'pre-emphasis' and 'equalisation' methodology to more than double the distance over which CameraLink cables may be used. This not only extends cable lengths at a fraction of the cost of using fibre-optic repeaters, but also maintains cable flexibility.

CEI is also able to make customised cables with overmoulded connectors; these normally give better shielding than a metal hood, as they are 360-degree taped with copper before the overmould plastic is applied. Working with the customer's 3D CAD drawings of the components that are to be connected, CEI can produce a stereo lithography (rapid prototyping) model for a modest charge. This enables the customer to check that the cable meets the space limitations before the overmoulding tool is made.

CEI is fully committed to investment in cable technology, and it says it will continue to invest in test equipment and remain at the forefront of new interconnect standards. CEI is already the cable partner for the new Coaxpress data transmission standard and is also the main supplier for the HS Link consortium.
