Standard snap-in terminals:
length (6.3

mm.
Also available with length of (4.5

All pin holes must be drilled into the
PC-board, since the unconnected pins serve
as mountings. These pins must be soldered
to insulated pads or pads with the same
potential as the negative pole.

Standard snap-in terminals:
length (6.3 +1/ 1.4) mm. Also available with
length of (4.5 1.4) mm. PET insulation cap is
positioned under the insulation sleeve.
All pin holes must be drilled into the PC-board,
since the unconnected pins serve as mountings.
These pins must be soldered to insulated pads or
pads with the same potential as the negative
pole.
