MatchClamp™ –

the captive cable entry

There are fields of application, in which conventional cable glands come up against their limits. Included here, for example, are vibration-proof sensor technology, dynamically acting industrial robots, life-saving respiratory equipment, tensile and vibration-prone rail vehicles, motors and driving gears, making high requirements on the fastening technology. Here, maximum impermeability and strain relief are just as much in demand as an extremely compact design. The MatchClamp™ range is precisely designed to meet these requirements, enabling cables to be led, for instance, into housing, equipment and plug-in connectors simply, safely, inseparably and, above all else, impermeably.

As with all PFLITSCH products, it goes without saying that MatchClamp features a very high degree of sealing with IP 68 and high strain relief: Depending on the cable with up to 500 N, the fastening technology attains up to 10 times the strain relief according to EN 50 262 compared to conventional standard cable glands. The MatchClamp sleeves are designed, made of aluminium, brass, copper, stainless steel and titanium, for the particular application requirements concerned and the customer’s cables. In the same vein, conductive as well as insulating surfaces are possible. Currently they are being realised for cable diameters between 2 mm and 30 mm.

Instead of being screwed, MatchClamp sleeves are simply pushed over the cable prior to assembly and after positioning with press clamps are inseparably connected to the cable. For this pressing procedure, PFLITSCH has developed a mobile electro-hydraulic pressing tool (Fig. 2+3), with which assembly can be done in a matter of seconds. With protective system IP 68, MatchClamp is water-proof up to 20 bar.

MatchClamp is impermeable to most gases, impact-resistant, sabotage and vandal-safe. As these cable entries can be bent to 90°, the upshot is stable kink protection without any additional expenditure. MatchClamp proves its superiority even in the EMC field: In order to safely conduct screened cables, the cable jacket is removed in the installation and the braided screen laid back over the cable. Now the assembly fitter pushes the MatchClamp sleeve over it until it contacts the braided screen. Any protruding braiding is removed, the sleeve positioned and subsequently securely press-fitted.
