How to Spec Custom Cables for Medical Devices

Creating a custom cable allows the designer to have control over conductor counts, AWG sizes, color codes, tolerances, insulation and jacket materials, shielding and print legends. Custom designs also allow control of overall diameters so that the cable will fit in existing ancillary components like grips, connectors, grommets, and strain reliefs. Moreover, custom cables make it easier to ensure that inferior cables are not substituted.

Cable Chain Design Guidelines

Chain Image

Of all the machine design details to worry about, cable carriers probably don’t top your list. Yet if you care about the reliability and uptime of moving machines, it pays to devote extra engineering attention to cable carriers and the components within them. A well-designed cable carrier will dramatically extend the life of cables and fluid power supply lines—by protecting them from damaging bends, crimping, abrasive wear and crushing.

Unfortunately, not all cable carriers are well designed. Their internal cavities may be too small for the components they carry. They may too long or short. They may be made from the wrong materials for the job. Or they may lack internal dividers.

These poorly-designed carriers can trigger the very same cable and supply line failures they were supposed to prevent, causing expensive machine downtime.
Fortunately, the potential for failures can largely by avoided by following simple carrier design guidelines developed by our Systems Group. Over the years, our engineers have designed, built and delivered thousands of populated cable carriers. Not only have these carriers contained our own power and signal products but also products from other suppliers, including air and hydraulic supply lines. These carriers have been implemented in a wide variety of servo and VFD applications, including ones with high flex requirements. Our carriers run day in and day out on a wide variety of packaging, automotive, processing, and industrial automation machines.

With so many populated carries under our belts, the design guidelines presented have been field tested and can add thousands of hours to a typical populated carrier. Read on for a detailed look at how to design populated carriers.

Dive into application details to specify the right cable

Choosing the best cable for an industrial application is one of the most critical design decisions of any complex automated system.

That said, cable selection is often an afterthought and not given the time or respect it deserves. As the lifeblood of the system, cables and wires are vital to transmitting power and sending control signal and data across wide expanses in a timely and reliable manner. Here we take a  look at some of the most important factors to consider when specifying industrial cable.

Customized products the norm in robotics

Robots today can be seen working alongside their human counterparts in almost all branches of industry, often taking on the work that is too difficult, too dangerous or that poses a health risk to humans. They can be seen lifting heavy loads, accurately applying paint into each little nook and cranny and repeating the same production steps millions of times with the same exact precision. Their movement sequences look like highly choreographed routines featuring extreme bending and rotary motions, demanding the highest levels of flexibility, stability and durability from all the components, integrated cables and cable systems used. The failure of just one component brings the entire production line to a standstill, causing losses running into the millions.

Connectors Lower Wiring Costs

LAPP Connector White Paper

Connectors Lower Wiring Costs-the assumption that hardwiring will minimize wire installation costs turns out to be wrong.

If you design or build industrial machines, you probably know all about hardwiring. It remains the most common way to bring
power and signal to the machine because it offers a perceived savings in installation costs. But the cost savings are really just
a mirage once you factor in the full range of wiring costs.
