971-LH (-DS)

PCB Connector

Screw connection, vertical wire entry, pottable

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

DESCRIPTION

The 971-LH series PCB screw connector with a pitch of 5 mm is particularly suited for potting printed circuits. For such potting applications, the solder pin is sealed at the housing opening against seeping casting resin. This PCB screw connector is available in 2- to 12-pole design and can be mounted side-by-side without pole loss. Wire protection in DS-design reliably prevents damage to stranded wires by the screw. The wire entrance is located vertical to the PCB - the casting resin surface is also vertical to the wire entrance. Version 970-LH alternatively provides wire entrance parallel to the PCB.
