Overview Catalogue group A PCB Plug-In Connector Systems Series 121 Conecta®: Pin strip connectors

Series 121: Pin strip connectors
This Plug-In Screw Connector System is available in various possible combinations. A reliable connection is provided at the screw side with a lift-terminal and at the plug-in side with a locked contact. The lift system ensures a high pressure fitting and a fatigue strength wire protection even after countless disconnections.

All types are available with 2 to 24 poles - the tier versions are available with 4 to 48 poles (with effectively double the pole density) - and can be stacked with the 120 series with 5 mm, with the 121 series with 5,08 mm space. The screws are captive.

Various special types are available on request. The blocks are unmarked as standard, but are available printed on request.
