Smart Features

The pilot tip, also called the lead-in section (highlighted in red), is a thread-free area on the connection side of the Powerelement.
Using the conical tip offers technical advantages, especially as an insertion aid for nuts:

• Simplified and more precise placement of nuts
• Prevents the nut from tilting, making it ideal for automated screwing processes

Due to the manufacturing process, threaded bolts have a thread run-out, meaning the thread does not extend all the way to the mating surface. As a result, the nut cannot be fully tightened when thin intermediate layers are used (e.g., when fastening cable lugs).
By adding an additional thread undercut (highlighted in red), the nut can be tightened down to the mating surface regardless of the thickness of the intermediate material. This provides the following advantages:

• Full thread engagement up to the seating surface
• Secure mechanical connection
• Improved electrical contact quality
• Optimized assembly friendliness
• Universal usability for varying material thicknesses

As standard, Powerelements with solid press-fit technology use pins with a 1.6 mm diagonal and a length of 3.5 mm. Depending on the PCB layout, it may make sense to adapt the pins to a 2.2 mm pin diagonal and a 3.0 mm pin length. This can lead to the following advantages:

• Higher current-carrying capacity per pin
• Fewer pin defects during manufacturing and handling (especially for bulk material)
• Improved stability and contact quality
