TE Connectivity BUCHANAN Family of Series — Terminal Block Connector System:

TE's Buchanan terminal block connector systems feature various wire termination methods including rising cage clamp, wire protector, spring, IDC, and crimp snap. Our product line offers a wide array of fixed and pluggable terminal blocks. Wire-ready raised screws are standard on BUCHANAN terminal blocks—no need to back off the screw first, just insert the wire and drive down the screw. The lower surface and edges of the clamping plates are carefully designed to securely clamp the wire—even combinations of different wire sizes—without severing stranded wire. Extra care has been taken to produce these components without burrs on any critical clamping surface or edges.

Standoffs help rid your PCB of any remaining corrosive agents during rinsing operations, this helps prevent trapped solutions in the immediate PC pin area. Significantly reduces the risk of post-wave corrosion problems. The acid-tin plating on our terminals means more than just improved shelf-life and superior solderability and is to provide the very basis for the heart of your wire connections. Tyco Electronics Corporation has been known for its plating, especially on the tin-plated components, and has maintained stringent plating specifications to provide a better performing, more reliable product. (Terminals meet or exceed Tyco Electronics Specification 109-11-1.) Terminal blocks and interconnect components are recognized under the Component Recognition Program of Underwriters Laboratories Inc. and Certified by Canadian Standards Association.
