321-LFS (-DS)
Screw/Solder Terminal Strip
Screw/solder tag connection, closed back on the solder tab side, pottable
DESCRIPTION
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.
