Extensions, Reroutings, Repairing

Existing connections and distributors frequently need to be moved due to changes in the functions of rooms, reorganisation of office space or relocation of machines and plants. The connected cables therefore have to be re-laid often too.

What happens when one or more cables are damaged when re-laying or it is discovered that they are too short for the new plans? An efficient, space-saving connection module solves the problem economically and saves the user time-consuming, cost-intensive re-cabling.

A connection module that can be installed easily with manageable costs and, most importantly, will not impair the performance of the cabling, solves the problem effectively and economically - especially when one universal module type can be used for a large number of different applications and ambient conditions. Such a module is suitable not only for lengthening cable lines but is also ideal for professional repairs to damaged cables.

Single or in Bundles

The times when bulky components took up a lot of space for cable extensions are over. Now, space-saving versions are available with a slim design which allows not only single cables but also whole bundles to be extended without problems. Versions for 19" installation in rugged wall-mounted housings and with mounting rail adapters for fitting onto DIN rails are also available, for example, in electrical distributors.

Connection Module VM-Pro 8-8

The connection module VM-Pro 8-8 Class  FA IP67 offers transmission properties up to Class  FA acc. to ISO/IEC 11801 and is suitable for installation and patch cables with 8 wires. Shielded and unshielded cables with solid and stranded conductors of AWG27-22 type and outer diameter of 5.5 - 9.0 mm can be connected with the VM-Pro 8-8 Class  FA IP67. Due to its compact shape the connection module is suitable for use in confined spaces.

Assembly of the VM-Pro 8-8 Class  FA IP67 connection module requires no special tools and is completed in a few steps. The mechanical stability, the insulated structure and the protection against external influences enables versatile use of the VM-Pro 8-8 Class  FA (1000 MHz) IP67 for laying and repairing cables in building, residential and industrial building cabling.

The IP67 connection module is shielded, insulated by the plastic screw glands, safe from manipulation and enables reliable strain relief.


Performance Characteristics

  • Class FA (1000 MHz)
  • real-time re-embedded
  • suitable for 100 / 250 / 500 / 1000 MHz installations and patch cables
  • connection via IDC termination
  • insulated construction (insulating resistance 30x 1012 Ω)
  • connection of 4-pair shielded/unshielded installation and patch cables from AWG27-22
  • pairs can be brought directly up to the terminal without untwisting the pairs
  • EMC compatible acc. to DIN EN 61000-6-1 and DIN EN 61000-6-2
  • suitable for PoE+ acc. to IEEE 802.3at
  • temperature range from -40° C to + 70° C
  • reconnectable up to 4 times

Connection Module Cat.7A

The VM 8-8 modules Cat.7are applied as connections /extensions of commercially available, shielded/unshielded twisted-pair installation cables (Cat.5e/Cat.6/Cat.6A/Cat.7/ Cat.7A) in the following applications: damaged cables, cable extensions, cable rerouting.

When VM 8-8 Cat.7modules are used, the cable segments in a structured wiring system do not need to be laid out again. This reduces the expenses for alterations and the overall costs to a minimum. Depending on the connection module type, up to 12 incoming and 12 outgoing 8-wire cables can be permanently connected together without any significant reduction in the transmission characteristics or any limitation of the maximum link lengths.
