SL-SMT 3.81/SL 3.81
BL 3.81
The 3.81 mm (0.51 inch) pitch connector
system extends the selection of connectors
available to the designer in the practical 3
mm range. The pin headers are available
with exit directions of 90° (horizontal) and
180° (vertical) relative to the PCB. The
system has been expanded with an SMT
variant.
The socket blocks with clamping yoke con-
nection are available with three different
cable-exit angle possibilities: 180°, 90° and
270°. Pin headers and socket blocks are
also available with screw flanges.
The Weidmüller PCB connectors are layout-
compatible with 3.81 mm connectors
currently on the market.

Reflow soldering is no longer restricted to SMD’s
(Surface Mount Devices).
Using a combination of special high temperature
resistant plastic and innovative component design,
Weidmueller has developed THT (Through-Hole
Technology) pin-headers and pcb terminals that can
be 100 % incorporated into the automatic pcb
assembly process.
These components are supplied as standard in car-
tons, or anti-static Tape-on-Reel packaging for inte-
gration into automatic Pick-&-Place machines.
The high-tech plastic has a melting point greater
than 300 °C and so is perfect for the Reflow solde-
ring process or higher temperatures associated with
Lead-Free Wave soldering.
The Weidmueller SMT/THR components aid the
reduction of overall production costs thus improving
manufacturing efficiency.

SMT/THR components, please review our SMT

Solder connection pin headers
Weidmueller’s standard THT(Through-Hole Techno-
logy) pcb terminals and connectors have been spe-
cifically designed for the Wave(Flow) soldering pro-
cess.
With the most frequently used pcb’s worldwide
being single layer 1.6 mm (0.062 inch) and 2.0 mm
(0.079 inch) thick, the solder pin length of pcb
terminals and connectors needs to be at least
3.2 mm (0.126 inch) long in order to provide
problem-free soldering.

Clamping yoke connection socket connectors
The screw clamping yoke is the most popular and
widely used cable connection method worldwide.
The security of the cable is vital for every applica-
tion, and the Weidmueller clamping yoke design has
proven its reliability for millions of connections in
hundreds of thousands of applications over the last
40 years.

When mounting PCBs, note that the rated data specified in the data sheet are with reference to the connection elements.
The required air gaps and leakage paths are to be adhered to for the given application in accordance with VDE 0110. To determine
the current-carrying capacity of the PCBs, DIN IEC 326 T.3 is to be observed.
Weidmüller PCB connectors are tested in accordance with, among others, standard DIN VDE 0627, for the specified field of applica-
tion. When used as intended, all requirements for applicable electrical, mechanical, thermal and corrosive demands are fulfilled.
