Screw/solder terminal strips
The following pages list our range of
screw/solder terminal strips
.
They have a scr
ew connection and their
solder connection is formed as a solder
tag
.
Our scr
ew/solder terminal strips are availa-
ble in 3,5 mm, 5 mm, 8 mm and 10 mm
pitch
.
Due to the lateral mounting flanges, large
cr
oss-sections and compact size, they are
suitable for every application
All versions use captive screws that are
ready to be wired and secured against
self-loosening
.
V
ersions of the 300 series can also be
combined with plug-in terminal strips
302-SV(-DS) and 322-SV(-DS)
.
Their pins
are pushed into the sockets and then
screw-connected
.

Screw/solder terminal strip
302-LF-DS
Screw/solder tag connection
09.13
W ECO Contact GmbH - www.wecogroup.com
The screw/solder terminal strip 302-LF-DS in 8 mm pitch is available with 1 to 12
poles. Due to the small pole spacing, it is well suited for applications where space
is limited.
The solder tag is formed as a wire protector. The wire protection reliably prevents
damage to multi-wire flexible conductors by the turning screw.
The screws are ready to be wired, secured against self-loosening and captive.
These strips can be combined with plug-in terminal strip 302-SV by plugging the
pins into the sockets and screwing them tight.
These terminals strips can be screw-mounted on a substrate.

Screw/solder terminal strip
302-NLF-DS
Screw/solder tag connection, low profile version
09.13
W ECO Contact GmbH - www.wecogroup.com
The screw/solder terminal strip 302-NLF-DS, lower version, is available in 8 mm
pitch with 1 to 12 poles.
Due to the small pole spacing, it is well suited for applications where space is
limited.
The solder tag is formed as a wire protector. The wire protection reliably prevents
damage to multi-wire flexible conductors by the turning screw.
The screws are ready to be wired, secured against self-loosening and captive.
The “N”-variant only differs from the standard 302-LF-DS version by the 12 mm
overall height (i.e. the moulding height is 3 mm lower). Note the shortened
clearance and creepage distances.
These strips can be combined with plug-in 302-NSV terminal strips by plugging the
pins into the sockets and screwing them tight.
These terminals strips can be screw-mounted on a substrate.

Screw/solder terminal strip
321-LFS(-DS)
Screw/solder tag connection, side of solder tag closed, pottable
09.13
W ECO Contact GmbH - www.wecogroup.com
pottable
The screw/solder terminal strip 321-LFS in 10 mm pitch was designed for larger
cross-sections than version 302-LF-DS. It is available with 1 to 12 poles.
Mouldings of this type are encapsulated on the solder tag side and therefore
particularly well suited for potting.
Socket and solder tag are manufactured in one piece.
The screws are ready to be wired, secured against self-loosening and captive.
These strips can be combined with plug-in terminal strip 322-SV by plugging the
pins into the sockets and screwing them tight.
The wire protector of the “DS”-version reliably prevents damage to multi-wire
flexible conductors by the turning screw.
These terminals strips can be screw-mounted on a substrate.

322-LFS(-DS)
Screw/solder tag connection

W ECO Contact GmbH - www.wecogroup.com
The screw/solder terminal strip 322-LFS in 10 mm pitch was designed for larger
cross-sections than version 302-LF-DS. It is available with 1 to 12 poles.
Mouldings of this type are open on the solder tag side but they can be connected
safe-to-touch as 2- and 3-pole version with cover caps A-323 and base plates
B-323. This will extend the creepage distance to the mounting surface.
Socket and solder tag are manufactured in one piece.
The screws are ready to be wired, secured against self-loosening and captive.
These strips can be combined with plug-in terminal strip 322-SV by plugging the
pins into the sockets and screwing them tight.
The wire protector of the “DS”-version reliably prevents damage to multi-wire
flexible conductors by the turning screw.
These terminals strips can be screw-mounted on a substrate.

Household Appliance DIN EN/IEC 60335-1
The screw/solder terminal strip 931-A-LFDS with a pitch of 3,5 mm is available in
2- to 12-pole design.
Due to the small pitch, it requires only little mounting space and is therefore well
suited for low-voltage applications.
The solder tag is formed as a wire protector. The wire protection reliably prevents
damage to multi-wire flexible conductors by the turning screw.
The moulding can also be mounted using the lateral flanges.
