SL-SMT 3.5 pin headers

At the pcb level, the SL-SMT 3.5 pin header ensures a cost saving in the production

process and, for field wiring, offers a free choice of connection technology thanks to an

extensive range in 3.5 mm pitch.

Packaging types of the SL SMT 3.5

The packaging of the SL SMT 3.5 was conceived for the typical component placement

process used for SMT components:

Automatic component placement:

Tape-on-Reel (ToR)

Tray

Manual component placement:

Standard box (Std)

The high temperature resistant SL SMT 3.5 pin header can also be used in the wave

soldering process, the advantage being that the plastic is resistant to high temperatures.

For this application however, standard pin lengths are needed. These are available on

request.

For the mounting of PCBs it should be noted, that the rated

data given in the data sheet relate only to the connection

elements. The necessary creepage and clearance paths must

be observed in connection with the respective applicant in

accordance to VDE 0110. The current-carrying capacity is to be

determined according to DIN IEC 326 part 3.

Weidmüller connectors are tested according to the DIN 0627

standard, and are valid for its field of applications. Provided that

the connectors are used for the intended purpose, all

requirements with respect to the occuring of electrical,

mechanical, thermic and corrosive stress will be satisfied.
