977 (-DS)
PCB Connector
Screw connection, with test holes
DESCRIPTION
The PCB connector 977 with a pitch of 7,5 mm is available in 2- to 8-pole design and can be mounted side-by-side in the nominal pitch. Due to their large clearance and creepage distances, these PCB connectors are particularly suitable for higher voltages. Wire protection in DS-design reliably prevents damage to stranded wires by the screw. The screws are secured against self-loosening. This PCB connector has test holes for ø 2 mm test plugs.
