Inquiry
We had a batch of 4mm² MC4 terminations last week where inconsistent crimp depth was causing pull-test failures, so I went looking for something with a ratchet mechanism that actually holds the die position through the full stroke rather than relying on operator feel.
It's a straight-shaft, 190mm long tool weighing about 450g with high carbon steel jaws that cover 2.5mm² up to 6mm²—which roughly translates to 14-10 AWG—and the ratchet doesn't release until you've completed the full cycle, which basically eliminates teh half-crimp problem we were seeing with cheaper pliers.
CE and RoHS certs are on file with the suplier, they offered a 1-year warranty (usually 2-4 weeks lead time, but confirm stock), and ergonomic red and blue handles are comfortable enough for repetitive use, though it's really not suited for field repairs on existing arrays where you'd need a compact tool for tight junction boxes—the straight shaft limits access in corners pretty badly.
Anyway, the model number is KNSN-2546B, and we're ordering a dozen units on standerd payment terms with the COA included per batch.
Yes, the KNSN-2546B covers the full range from 2.5mm² to 6mm² (14-10 AWG) without needing to swap out dies. The single straight die handles all those sizes for MC4 terminals.
It's a standard ratchet mechanism that locks the handles until you complete the full crimp cycle. You can't release it mid-way unless you force the release lever, which we don't recommend.
Yes, we can include the CE and RoHS certificates upon request. Just let your sales rep know when placing the order, and we'll pack them with the tool.
MOQ is 50 pieces for this model. We can mix red and blue handles in the same shipment, but the total still needs to hit that 50-piece minimum.
Keep it in a dry environment, ideally below 60% humidity. A light coat of machine oil on the steel head every few months helps, especially if you're in a coastal area.
