## **Product image** 

PUSH IN - Weidmüller's innovative connection system simplifies the wire connection process. The benefits for users and applications: 

- High packaging density due to very low component height. Simply insert the prepared wire - finished 

- High component density with the compact SCDN / SCDN-THR two-tier pin header 

- Simplified processing due to integrated push buttons for opening the clamping unit 

- Intuitive handling – since the wire-entry area and handling area are clearly separated
