Two and Four Position Link Connectors

3M link connectors use the advantages of 3M's IDC technology, designed to provide a safe and reliable electrical connection while enabling T-Tab termination as well as cable extensions. The link connector, 381 series is a hermaphroditic connector (can mate to itself), reducing the number of different interconnect products needed for wiring. Link connectors are designed to terminate easily in the field using a standard pair of pliers, and do not require any special tooling or pretreatment of cables. The termination process reduces labor installation costs relative to traditional interconnect alternatives. In some Fieldbus applications, in combination with 3M power clamp connectors or 3M mini-clamp connectors, wire usage reduction of 70% is possible. No cable prep is needed in the termination process; simply squeeze the connector with a pair of pliers.

Features
  • Hermaphroditic four-point contact mating structures reduce the number of different components required to interconnect, ensuring a reliable interconnect
  • Easy, labor saving and reliable IDC termination
  • T-Tap termination enables mid-cable terminations without special preparation or handling of the cable or wires in order to interconnect Fieldbus and power lines at any point
  • Easy field termination with a pair of pliers - no special wire preparation, stripping, tinning, or special tooling
  • Easy field termination with a pair of pliers - no special wire preparation, stripping, tinning, or special tooling
  • Design accepts multiple wire diameters of 1.1 mm to 2.54 mm, conductor sizes of 18 AWG to 22 AWG
  • 5 Amp maximum current carrying capability per contact
  • Latching mechanism maintains a reliable interconnection in demanding field applications
