Purchase now: Weidmüller PZ 4 Roto L Crimping Tool
Purchase now: Atlantech Drives provides you the Weidmüller 9027290000 (Model: PZ 4 Roto L), the specialized **Rotatable Crimping Tool** for smaller wire cross-sections ranging from **0.14 mm² to 4 mm²** (AWG 26…12). While the PZ 6 covers up to 6mm², the PZ 4 Roto L is optimized for the lower range, offering a slightly more compact crimp profile ideal for high-density terminal blocks where every millimeter of ferrule width counts.
Technical Specifications and Rotatable Die
The standout feature is the **»Roto» Die Head**, which can be locked in either a **front-entry** or **side-entry** position. This patented design allows electricians to crimp wires in tight spaces without twisting their wrists or the cable. The tool produces a **Trapezoidal Crimp** that complies with DIN 46228 standards. The ratchet mechanism ensures that the crimp cycle is always completed, preventing under-crimped (loose) connections that could lead to overheating.

Expert Tips: Avoiding «Birdcaging»
Bad stripping ruins crimps. Expert Tip: When using the PZ 4 Roto L on fine stranded wire (0.25 – 0.5 mm²), ensure your wire stripper does not nick the strands. If strands are splayed out («birdcaged») when inserting into the ferrule, they can get caught on the plastic collar. Twist the strands slightly (but not too much!) before insertion to ensure all copper enters the metal tube for a perfect gas-tight crimp.
Frequently Asked Questions (FAQs)
Q: Why choose PZ 4 over PZ 6?
A: If you work exclusively with control wiring (0.5 to 2.5 mm²), the PZ 4 crimp die is slightly tighter tolerance for the small sizes, ensuring the ferrule fits perfectly into miniature push-in terminals.
Q: Can I crimp 6mm² wire?
A: No, the maximum capacity is **4 mm²**. For 6mm², you strictly need the **PZ 6 Roto L** (1501390000).
