971-FB

Socket Terminal Strip

Plug connection, vertical plug-in

https://wecoconnectors.com/wp-content/uploads/Images/971-FB-R.JPG

DESCRIPTION

The socket terminal strip 971-FB with a pitch of 5 mm is available with 2 to 32 poles. In order to achieve a higher housing strength, these socket terminal strips cannot be mounted side-by-side without pole loss. It is suitable for a parallel connection of two PCBs, when using male pin strips of the series 971-SLR, -SLS oder -SLW. For this version, the plug direction for mating connectors is vertical to the PCB. The contact pressure is achieved by means of a stainless steel spring with extra-long spring deflection. Due to the high spring forces, it is advisable to select the socket terminal strip with only up to 8 poles. For longer clearance and creepage distances, socket terminal strips are also available in a larger pitch. The socket terminal strip 971-FB only differs from the smaller 951-FB version by the M3 screws and longer clearance and creepage distances. It is fully compatible to versions 951-SV, 97..-FBW and -FBS.
