PC board connectors
edge card pluggables
PCB
Edge card pluggables offer the advantages
of standard pluggable connectors, but
without the requirement of the mounting
header.
System features
❐
installation and maintenance friendly
❐
easy-to-operate screw termination
❐
quick disconnect
❐
clear, organized wiring
❐
thickness of PC board: 1.4 mm
to 1.8 mm
❐
floating contact springs
❐
secure, robust clamping mechanism
Coding
❐
coding without pole loss
❐
PC board with coding slots accept
coding pieces inserted into the plug
Fixing brackets
❐
for secure connection of printed circuit
board and connector
❐
special fixing brackets as guides for
large PC boards. With fixing bolts on the
sides at the top and bottom which
fix backing strips creating a stable
guiding frame.
Material
Metal parts:
❐
made from special alloys and/or
special surface treatments
❐
minimum feed through resistance
❐
high corrosion resistance
Insulating housings:
❐
use of high-quality polyamide
for its excellent electrical, mechanical
and chemical characteristics
(see
facts
& DATA
:
Technical information)
❐
materials as per US standard UL 94-V-0
❐
colors: gray, similar to RAL 7032
Note:
The information regarding cross
sectional areas and connection types
pertains to connections without
ferrules.
The indicated rated current corresponds
to the maximum load for the
PC board connector with a connected
wire of the indicated rated cross section.
The rated voltage is indicated as per
DIN VDE 0110 part 1 (IEC 60 664-1)
– insulation coordinates for electrical
material in low voltage application – and
refers to the delivered state of the PC
board connector.
Marking
❐
smudge-proof inkjet marking directly
on the connector
❐
custom marking possible, consult
factory
❐
clear, easily legible marking
Before the PC board is fitted with
connectors, an appropriate PC board
must be selected and dimensioned
accordingly (e. g. regarding tracking
resistance of the printed circuit board,
distances of the leads and solder joints).
Furthermore, the ambient conditions
under which the materials shall be used,
must be considered.
The indicated rated voltages will be valid
for the complete module only if the
printed circuit board and its connectors
are correctly and clearly adjusted to
each other.
Abbreviations for plastic materials:
PA 66/6 = Polyamide 66/6
PC
= Polycarbonate
PBT
= Polybutylenterephthalate
Variety of types
❐
in 3.5 mm and 5 mm spacing
❐
pole configurations from 2 to 24 poles
❐
cross sections up to 1.5 mm
