Altech is pleased to announce a new, more
extensive printed circuit board terminal block
line. This line offers the standard single and
double level fixed and pluggable terminal blocks
in metric and US pin spacings. However, this
product line goes beyond our past standard
offering. There is now a wider array of products
within each pin spacing as well as new types of
blocks such as 35°, reverse horizontal wire
entry, and triple level fixed blocks, card edge
connectors, panel feed through blocks, barrier
strips, and plugs/headers with screw flanges.
This product assortment combined with the new
pricing structure makes this line extremely
competitive.
Altech printed circuit board terminal blocks give
you highly dependable connections without the
need for wire lugs. Choose either tubular screw
clamps or box clamps when economy is
paramount or screw-cage clamps for heavy-duty
applications. In each case, simply strip and insert
the wire and tighten the screw. We recommend
the use of ferrules, especially for export
applications and whenever fine stranded wires
must be terminated.
Our board mounted terminal blocks meet or
exceed most international standards and are
accepted worldwide. They’re available in single,
double and triple level configurations with both,
millimeter and inch pin spacings. All leave mini
footprints to save valuable real estate.

Our printed circuit board terminal blocks designed for fixed
mounting offer high density, and maximum flexibility. Modular
construction simplifies ordering and reduces inventory. Two-and
3-pole modules can be interlocked to create multipole
assemblies. Altech can also supply ready-made assemblies
tailored to your specification. Fixed-mount blocks are available
with the economical tubular screw, box clamp or the screw-cage
clamp and offer several wire entry options to facilitate wiring
and increase accessibility.

Each clamp style is offered in metric and inch pin spacing. For
your convenience, this catalog is organized by pin spacing.
Fixed blocks are first, starting with the smallest pin spacing,
then pluggable shown in each available spacing.

LUGGABLE
The two-piece, plug and header design of our “pluggable”
terminal blocks speed and simplify board replacement and
reduce costly downtime and misconnections. No special tools are
required. Headers are soldered into the board and accept the
plugs, which are easily removed for fast, convenient board or
device replacement. Choose single- mold designs for maximum
strength. Or choose modular designs which are assembled from
2 and 3 pole modules when you need maximum flexibility to
meet changing requirements. Both are available in a variety of
configurations. Headers are available in vertical, and
horizontal, single or double-level, with closed or open ends.
We offer pluggables with either screw-cage clamp termination for
heavy duty requirements or with tubular screw termination and
open headers for cost sensitive applications. We also offer a card
edge connector for a quick, reliable and inexpensive connection.

ATERIALS
All of our printed circuit board terminal blocks feature precision
formed or machined metal parts which are electrolytically
plated. Nickel or tin-plated brass cage clamps or tubes, wire
protectors, and tin-plated solder pins satisfy the most
demanding requirements. Housings are precision-molded from
self-extinguishing polyamid 6.8 or glass-filled polyester
providing excellent strength and temperature resistance.

Altech’s printed circuit board terminal blocks give you a choice
between tubular screw, box clamp and screw-cage clamp
designs:
• When your application calls for the highest reliability and
frequent wire terminations, the screw-cage clamp should be
your choice. As the clamp is tightened, the nickel-plated cage
rises, pressing the wire firmly against the busbar, ensuring
solid connections every time. Standard color is green.
• In the tubular screw and box clamp design, tightening the
screw presses the conductor directly against the bottom of the
clamp. These systems are ideal for cost sensitive, lighter duty
applications or applications with infrequent wire terminations.
Wire protectors are standard. Standard color is black for
tubular screw and green for box clamp.
Altech offers marking to identify terminal inputs. Order Hot
Stamp Imprinting for permanent marking of large quantities or
custom marked terminals. Standard marking is consecutive
numbers, left to right. This standard marking can be ordered by
adding the imprint sequence to the part number as a suffix
(i.e. MV-4612/1-12 would be a MV-4612 terminal block
imprinted 1 through 12, left to right).
Custom imprints are also available, consult Altech for ordering
information.
