PUSH IN - Weidmüller's innovative connection system
simplifies the wire connection process.
The benefits for users and applications:
• High packaging density due to very low component
height. Simply insert the prepared wire - finished
• High component density with the compact SCDN /
SCDN-THR two-tier pin header
• Simplified processing due to integrated push buttons
for opening the clamping unit
• Intuitive handling – since the wire-entry area and
handling area are clearly separated
• tool-free locking and releasing when using Weidmüller's
patented release latch (LR)
The Weidmüller plug-in connectors, pitch 3.81 mm (0.15
inch), are compatible with the layout of customary plug-in
connectors, can be coded and provide space for printing.

For the mounting of PCBs, it should be noted that the
rated data given in the catalogue relates only to the
connection elements. The neccessary creepage and
clearance paths must be observed in connection with
the respective applicant in accordance to VDE 0110.
The current-carrying capacity and pitch tolerance is to
be determined according to DIN IEC 326 part 3 very fine.
Weidmüller connectors are tested to the DIN VDE 0627
standard, and are valid for its field of application.
Provided that the connectors are used to the intended
purpose, all requirements with respect to the
occuring of electrical, mechanical, thermic and
corrosive stress will be satisfied.
