TE Connectivity, Power Connectivity

Power Connectivity

Often left for the latter stages of a design for many server, storage or switching applications, power requirements can sometimes be the most challenging, requiring the most agile solutions for whatever space and cost may be left to work with. Capable, space-saving products that are modular and efficient are critical.


MULTI-BEAM XLE connectors feature a new 3-beam contact, made from a thicker (higher) conductivity material than the original single-beam or 4-beam designs. The new 3-beam design allows for a greater angular mis-alignment between mating connectors and offers a lower mating force.


Two hot-pluggable power contacts to choose from:

  • 50 Amp high power contact
  • 20 Amp low power contact
  • Over 40% lower mating force than original MULTI-BEAM XL connectors
  • Over 40% more current in the same overall PCB space
  • Low-wear contact design passes Telcordia environmental exposure requirements
  • New design allows more angular mis-alignment

RAPID LOCK Connectors

TE Connectivity, Rapid Lock Connectors

TE offers a wide selection of blind-mateable “drawer” connectors to suit modular equipment designs. The term “drawer connector” was created to describe a cabinet drawer where the connector is installed at the back of the drawer and is mated by closing the drawer. Since the “drawer” is often times made with a somewhat loose fit — to enable easy opening and closing, the drawer connector must provide sufficient self-alignment and ideally a floating connection to the cabinet or drawer to keep the connection from binding.


  • Wide variety of contact sizes and styles from 1 Amp signals up to power contacts rated at up to 200 Amps each
  • Sequenced contacts for “mate-first-break-last” operation
  • Floating panel-mount connectors float up to +/- 2 mm
  • High durability specific products ranging from 100 to 1000 mate/un-mate cycles
  • Customizable products allow the freedom to add or remove power or signal contacts to meet specific application requirement
  • Most products recognized to US and Canadian requirements under the Component Recognition program of Underwriters Laboratories File No. E28476
