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

- High component density because of small pitch. Simply insert the prepared wire - and you're done 

- Simplified processing, thanks to integrated push buttons for opening the terminal point 

- Intuitive handling – since the conductor entry and handling areas are clearly separated

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
