3M Scotchlok UR2, UY2, and UB2A Connectors are among the industry's original IDC connectors. They feature technological advantages such as full wire range capability, increased port size to accommodate various insulation sizes, double elements in all products, and a new solvent resistant plastic construction.
The Scotchlok Series 2 connectors—UR2, UY2 and UB2A—extend the original IDC connector design with larger port sizes, full wire‑range capability, double elements and a solvent‑resistant plastic construction. The UR2 is a general butt‑splicing connector, the UY2 is a compact version for higher‑pair‑count bundles, and the UB2A is a tap‑splicing connector with a pre‑crimp feature for quick installations. All three are available in standard and dry (‑D) versions and can be used with solid copper conductors of 19‑26 AWG.
