TE CONNECTIVITY INSTALLATION COMPONENTS AND OTHER PRODUCTS
OVERVIEW OF HIGH-QUALITY ELECTRO-TECHNICAL ACCESSORIES.
Electro-technical accessories, such as connectors or heat-shrink tubes, determine the life cycle of numerous installations. They are particularly important when installed in vehicle, industrial automation or heavy machinery cabling systems. It is good to check, then, what distinguishes TE Connectivity products among other solutions.
This article presents the range of products supplied by TE Connectivity, a manufacturer that specialises in producing connectors, installation accessories and electro-mechanical components. Selected products from this range can be used in numerous applications, and they are featured in several sections of our catalogue. Obviously, we are not presenting the full assortment of this supplier here, but only its relatively small part.
This article covers the following issues:
• Types and applications of heat-shrink components
• Creating installations using rail-mounted connectorsand blocks
• Most popular types of connectors
• Power relays included in the TE Connectivity product range
Heat-shrink tubes and profiles
The range of heat-shrink tubes and profiles offered by TE Connectivity includes a few hundred items. It results from the variations concerning several parameters. One of those is the tube diameter that can range from 1.2 mm to 101.6 mm( before shrinking at a ratio of 1:2, 1:3 or even 1:4). This diverse range alone suggests that these products are designed for numerous electro-technical applications, i. e. in the field of electronic engineering, commercial electric engineering, and also industry and power generation, such as creating power supply lines for buildings. For the latter, i. e. high-current installations with largediameter cables, profiles with enhanced mechanical strength that is ensured, in the case of TE Connectivity products, by cross-linked elastomers, are the most common choice. Such components are divided into two main product categories: profiles and breakout boots. Profiles come with several functions, as they stiffen and reinforce the areas of straight or angular wire routing, and seal any reduction points, e. g. where a cable is inserted into a connector, pipe or conduit without a gland. Break-out boots ensure the continuity of the outer sheath in locations where a power or control cable is opened and separated into individual conductors( from 2 to 4), so that they eliminate the risk of contaminants and moisture penetrating the cable, which in turn could lead, for example, to the hydrolysis of the inner insulation layers.

Note that the products presented here include heat-shrink elements that are additionally coated with adhesive( on the inside), which melts under the influence of the shrinking temperature to ensure tight and firm adhesion to the surface covered. It is particularly important when securing not only electric cables, but also pipes and hoses used to transport various liquids. The majority of TE Connectivity heat-shrink accessories is made of polyolefine that is resistant to exposure to numerous substances, such as oil, petrol or grease. Note also that small-diameter heat-shrink tubes are available in numerous colour versions to facilitate consistent labelling of power supply and signal lines, not only in three-phase systems.
Glands and other accessories
1SNG601190R0000 Polyamide gland ensuring IP68 degree of protection.
The TE Connectivity product range encompasses various mechanical installation components. These include glands made of plastic( polyamide),( nickelplated) brass or stainless steel. Their sizes are adjusted to lines and pipes with diameters ranging from 2 mm to 55 mm. They ensure a high degree of protection( IP68), i. e. full dust tightness and water resistance, also to pressurised water jets. Gland seals and nuts are available in sets or individually, which facilitates the selection of optimum solutions for each typical application. Additional products for those cabling accessories include caps with diameters ranging from 4 mm to 44.2 mm, as well as thread adapters. Moreover, TE Connectivity offers multi-circuit cable conduits.
