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.

THR solder connection pin headers
SL-SMT 3.81/90G
SL-SMT 3.81/90G Box
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
