I’m sure if I thought longer I would come up with more differences between these two systems, but I think we’ve covered the main points. Is cost, primarily in assembly and manufacturing time, and tooling and assembly We frequently pull pins between - in other words, selectively populate - the plastic insulator to meet creepage and clearance requirements.Ĭontact systems are available in a large variety of design and manufacturing options: a variety of wire gauges, pin sizes,Ĭenterlines, latches, and options to increase the ruggedness of the system. They may design a smaller pitch termination on their PCB to save real estate. Perhaps the most common application is a designer needs to connect their PCB to a PCB or device from another supplier. A common example is switching from 2.54 pitch to 2.00 mm pitch. It is popular on 2.54 mm pitchĬonnectors because those contact systems accept a wide range of wire gauges,Ĭrimped connector assemblies let designers transition from one connector pitch to another. This design can save board space, and it canĪllow the designer to use fewer connectors. Use two or more wire sizes in one cable assembly, allowing the same connector You can also do this with IDC, but you have more flexibility and options with crimped connectors.Ĭrimped contact cable assemblies allow two or more wire sizes in one cable assembly As mentioned previously, IDC cable assemblies pretty much have to go straight ahead and can’t bend.ĭiscrete wire assemblies can break-out from a higher pin count connector to several smaller position connectors. Crimped Connectors (Discrete Wire)īecause cable assemblies with crimped connectors almost always incorporate discrete (individual) wires and not ribbon cable, these crimp cable assemblies can fit into some tight areas that ribbon cable can’t. They can bend, angle, and flex into some tight bends and small nooks and crannies. Relatively straight line, or with minimal bends and angles. Pretty much has to travel from one point of termination to another in a In our opinion one of the biggest disadvantages of ribbonĬable and IDC is the cable is relatively inflexible and stiff, and the cable In the assembly process the metal blades penetrate any surface Mating connectors for the IDC cable assembly incorporate options to increase the ruggedness of the assembly with features like locking clips, ejection latches, strain relief, and polarization, to name just a few.Īssuming you are purchasing your components from a reputable connector supplier (like Samtec!), IDC’s are gas-tight and vibration-proof because of the quality of the design and manufacture of the contacts and plastic insulators which house them. ![]() They are available in a variety of wire gauges, pin sizes and centerlines. It’s so accepted that connector companies offer a large variety of design and manufacturing options. IDC has been around since the 1950’s and is an accepted connector design. ![]() For that matter, generally, much lower forces are required to terminate the ribbon cable to the IDC contacts. Most IDC’s can be terminated by a basic hand press or other simple tool. The insulation on the wires does not have to be stripped prior to termination, or soldered, or individually crimped. This saves a lot of time and therefore money. ![]() Literally dozens wiresĪnd contacts can be terminated at one time. Quicker, and therefore less expensive, to manufacture. Crimping usually requires a specialised crimping tool …”ĭiscrete wire connectors come in a variety of centerlines, sizes, shapes, and wiring configurations. ![]() “Crimped connectors are a type of solderless connection, using mechanical friction and uniform deformation to secure a connector to a pre-stripped wire (usually stranded). Crimping is used in splice connectors, crimped multipin plugs and sockets, and crimped coaxial connectors.
