BUCHANAN Terminal Blocks

are RoHS Compliant.
Barrier Strips – Overview
Two Types of Barrier Strips
and a Line of Sockets:
Tri-Barrier
Three walls or barriers
surround each terminal
screw. The back wall
safeguards field wiring.
Dual-Barrier
Two walls or barriers are
molded on each side of the
terminal screw.
Sockets
Mounted directly to the PC
board, the Barrier Strip is
plugged into the socket.
The socket expedites field
maintenance. (Below, a
tri-barrier is about to be
mounted in a socket.)
Wire Clamp Screws
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.
Resilient Plastic Barriers
Flexible thermoplastic
material for terminal blocks
was an especially important
feature at the time of its
introduction, since many
earlier blocks were molded
of more rigid, brittle
thermosetting plastic
compounds.
Wire-Ready Raised Screws
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. Wire installation time
and effort are virtually cut in
half.
Integral Standoffs
Standoffs help rid your PCB
of any remaining corrosive
agents during rinsing
operations. Helps prevent
trapped solutions in the
immediate PC pin area.
Significantly reduces the
risk of postwave corrosion
problems.
Gas-Tight Connections
The acid-tin plating on our
terminals means more than
just improved shelf-life and
superior solderability. It is
to provide the very basis
for the heart of your wire
connections.
Quality Plating
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.)
UL Recognition and CSA
Certification
Terminal blocks and
interconnect components
are Recognized under the
Component Recognition
Program of Underwriters
Laboratories Inc. and
Certified by Canadian
Standards Association.
