With the new blueglobe TRI®, PFLITSCH is offering for the first time an EMC cable gland that sets standards in terms of shield bonding and dampening values – precisely for applications with high-grade double shielding.
For years, PFLITSCH cable glands with the UNI IRIS® annular spring have been proving their value in applications where conventional EMC cable glands reach their limits. The new EMC solution blueglobe TRI® with the triangular contact spring offers even more and combines outstanding HF dampening values and easy assembly with the other system characteristics of blueglobe that are clearly above the EN standard 50 626. This new EMC variant initially comes in the sizes M16 to M32 for cable diameters from 7 to 25 mm. Planned are types between M12 and M80 in brass and stainless steel.
Once the sheathing is uncovered, the cable can be simply pushed through the blueglobe TRI®, whereby the triangular spring reliably encompasses the sheathing straightaway without the pressure screw having to be tightened up. With conventional EMC cable glands, on the other hand, there is the risk of exercising mechanical pressure on the sheathing when the sealing is pressed, which may lead to changes in the shielding effect. blueglobe TRI® attains dampening values of 80 dB up to (or at) 100 MHz and in the frequency range up to 2,5 GHz with values of 50 dB minimum. Because of the configuration of the spring catching in the meshwork while dismounting it is impossible.
blueglobe`s unique concept with the spherical sealing insert is already setting standards: Compared to conventional products, these cable glands attain maximum clamping ranges, maximum tightness of up to IP68 and the best strain relief – with simultaneously gentle sealing not irreversibly constricting the cable. In the two types M25 and M32, for example, all cable diameters from 25 to 34 mm can be securely sealed, while conventional glands need up to 4 sizes. This reduces the outlay for ordering and storage right up to assembly and spare-parts procurement.
