What is an insulation-displacement connector? What is the difference between IDC, LSA and LSA+?

An IDC connection refers to a solderless, screwless and stripping-free connection technology that is used for connecting communication cables in telephone and data technology. The LSA-Plus system is the common European alternative to 110 block. 
The connection is made with LSA connection modules. The punch-down blocks are equipped with a series of slots into which the individual wires of the telecommunication cable are inserted and secured with a special insertion tool, the LSA tool. The tool presses the wire into the slot and a contact blade edge cuts through the insulation, creating a metallic connection to the wire while cutting off the excess wire. This technology is widely used in the telecommunications industry due to its simplicity, reliability and the ability to make connections quickly and without specialised knowledge. 
LSA+ or LSA-Plus is a further development of IDC technology. The most important difference is the angle of the insulation displacement connectors to the cable. With IDC connectors and original LSA modules, the insulation displacement connector is at an angle of 90° to the cable, with LSA-Plus it is 45°. The inclined position of the LSA+ connection creates a kind of suspension that improves the contact. EFB-Elektronik always supplies LSA and IDC connectors with the improved LSA-Plus technology.  
IDC connections can be found in various environments, including:
  • Patch panels in network cabinets
  • Main distribution frames (main distributors) in telecommunications facilities
  • Sub-distribution boards in building cabling
  • Junction boxes and surface-mounted or flush-mounted distributors in the field of building automation

Telecom equipment for IDC connections – ready to order from EFB-Elektronik

In the field of telecom equipment, EFB-Elektronik offers you a comprehensive range of modular cables, IDC cables and connection and disconnection modules as well as junction boxes and distributors and other accessories. 
LSA connection modules: LSA connection modules are the actual connectors within IDC systems on which the individual cable cores are laid. 
LSA disconnection modules: LSA disconnection modules are a special type of connection block used in cabling technology to enable a separating function between two cabling areas. By opening or removing the separator, a physical and electrical separation can be created between the two sides of the strip. This is particularly useful for testing, troubleshooting and maintenance work, as it allows individual cable segments to be isolated without dismantling the cabling.
LSA boxes & distributors: LSA boxes contain multiple IDC modules and are used in a variety of environments, from small office networks to large telecom distribution systems. They provide a reliable and easy-to-maintain interface between the field cabling and the technical equipment. In the EFB-Elektronik online shop, you buy unequipped LSA connection boxes and distributors in various sizes for 20 to 200 twin wires. We also have wall-mounted and floor-standing distribution cabinets for 300 to 1800 wire pairs in stock. 
IDC cables: We offer LSA connection wires with 2, 4 or 6 cores and four-core modular flat cables in 100 metre rolls permanently in stock. We also offer LSA patch cables with RJ45 connectors as well as test and connection cords with other connector types. We manufacture customised LSA cables for you in our cable assembly department. 
LSA overvoltage protection: LSA overvoltage protection is used to protect sensitive devices and systems from overvoltages. These can be caused by lightning strikes, switching operations in the power grid or other sources of interference. Such surges can damage or even destroy the connected devices if they are not adequately intercepted. Our online shop therefore offers you high-quality and reliable overvoltage arresters and overvoltage protection magazines for your IDC connection.

Telecommunications equipment & modular cables

In addition to LSA components, EFB-Elektronik also offers telecom equipment such as RJ modular cables, adapters and ISDN patch panels for fast and reliable telecommunication connections:
Adapters: Cat.3, Cat.5e and Cat.6 T-adapters as well as ISDN adapters and multiport adapters for cable sharing with 2, 4, 5 or 8 sockets for RJ45 plugs 
ISDN patch panels: ISDN patch panels with 25 or 50 sockets
Telecom cables: Modular cables with RJ45 connectors on both sides and different numbers of cores in lengths of 1 metre, 1.5 metres, 2 metres or 3 metres
