FIXED
Our printed circuit board termi-
nal 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 inter-
locked 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.
PLUGGABLE
The two-piece, plug and
header design of our
“pluggable” terminal
blocks speed and sim-
plify board replacement
and reduce costly
downtime and miscon-
nections. 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 inexpen-
sive connection.
CONNECTION
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 bus-
bar, 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 infre-
quent wire terminations. Wire protectors are
standard. Standard color is black for tubular
screw and green for box clamp.
PIN SPACING
Each clamp style is offered in metric and inch
pin spacing. For your convenience, this cata-
log is organized by pin spacing. Fixed blocks
are first, starting with the smallest pin spacing,
then pluggable shown in each available spac-
ing.
MATERIALS
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 provid-
ing excellent strength and temperature resist-
ance.
MARKING
Altech offers marking to identify terminal
inputs. Order Hot Stamp Imprinting for per-
manent marking of large quantities or custom
marked terminals. Standard marking is con-
secutive numbers, left to right. This standard
marking can be ordered by adding a suffix
(i.e. MV-4612/iA would be a MV-4612 terminal
block imprinted 1 through 12, left to right).
Custom imprints are also available, see page
177 for ordering information.
