brown, purple and blue. Consult factory.
All WAGO PCB mount terminal blocks can be soldered to the board
manually or via automated wave solder process. THT is the most widely
accepted technology for connecting the terminal block to the PCB.
Through-Hole Technology (THT):
WAGO (THR) terminal blocks are made of a special plastic to withstand
the high temperatures experienced in the reflow solder process. This offers
tremendous time and cost savings as they can be soldered to the printed
circuit board in one stop with other SMT components.
Through-Hole Reflow (THR):
PressIn-Technique:
Allows direct connection of WAGO terminal block pins to the printed
circuit board without the use of solder. This technology is particularly
effective when all other components are pre-applied to the PCB
using surface mount technology (SMT). Also great for
prototyping.

3. PCB Terminal Blocks
Connection technology for the printed circuit board

4. RoHS compliant
CAGE CLAMP®
connection
The universal connection
technology with over 25
years of proven reliability
for solid and stranded
conductors ranging from
28 AWG up to 6 AWG
for printed circuit board
applications.
CAGE CLAMP®
S connection
An innovative connection
technology that combines
the universal benefits of the
classic CAGE CLAMP®
with
the advantages of a push-wire
connection.
Push-wire connection
A specially designed
connection technlogy for
quickly terminating solid
or ferruled stranded
conductors. Simply push
to terminate; no tools
required. Also rated for
stranded wire with lever or
screwdriver actuation.
IDC
Insulation displacement
connection technology for
connecting solid wire without
stripping. This connection
method is particularly efficient
for automated wiring, i.e., the
lighting industry.

WAGO PCB Connection Philosophy
With a pre-programmed clamping force that adjusts automatically to the wire size, the WAGO spring
pressure clamping technology - in contrast to screw clamp technology - guarantees a reliable connection
regardless of the installer‘s experience. The result is a connection that is vibration-proof, thermal cycling
resistant, corrossion resistant, maintenance free, and up to 50% faster.
