Crafted from industrial-grade carbon steel with rust-resistant treatment, it features EDM-cut jaws for damage-free crimps and a smooth ratcheting mechanism that cuts hand effort by half. Its ergonomic design with angled head and non-slip handles ensures comfort during extended use, making it the go-to crimper for electronics pros and DIYers aiming for perfect, reliable connections every time. ## Description iCrimp SN-01BM Ratchet Crimper AWG28-20 for XH2.54/3.96,PH2.0,PX,JST,Molex Terminal - desertcart.com Review: Quality tool that works well. - I use this tool for crimping JST XH pins. I gave it 5 stars for ease of use but crimping these small pins is not easy; at least not yet since I am a complete novice to crimping those pins. Positioning of the pins in the tool is the difficult part. Once that is accomplished the tool operation is easy. I also purchase a kit with pins and connector housings. Many of my first crimps were near failures in that the retaining tab was crushed back into the pin and I had to dig it out for the pin to function. I also purchased pins from a popular electronic components company that worked much better in that there was more clearance for the retaining tab to be clear of the tool for the crimp. There was also more spacing from pin to pin on a string of pins. Keeping the pin on a short string rather than breaking the pin off an then trying to insert it into the tool makes pin insertion more manageable. The slightly wider distance between pins helps. Review: WOW! A decent crimper for dupont connectors. - I do a lot of automation work using Arduino and Raspberry Pi for things like sensors, fans, etc. I'm OCD about having perfect cables/connections. I have tried five crimp tools and even after dialing in the right crimp pressure and inspecting every crimp and making sure the insulation crimp was flat but often have the last insertion in the housing blow out the sidewall of the housing or ruining the crimp trying to force the pin into the housing. I read an article the other day on hackaday.io about using the proper tool for the job and the author recommended the $425 manufacturer's tool for the perfect crimp. Way too expensive for my needs. Realizing that, he recommended this crimp tool as second best. It turns out, most low cost crimp tools form an elliptical crimp making it hard to insert the pin into the housing. It also seems to spread the sidewall of each position out so the last position would blow out the side wall. The uneven force of an elliptical shaped crimp can also increase the resistance of the connection. This crimp tool is different in that the shape of the jaws makes for a more circular (cylindrical) crimp even on the insulation part of the crimp. I received this tool yesterday and this morning started to make some test crimps on 26 and 28 awg wires. When I pushed the pins into the housing, they just slipped in so easily I couldn't believe it! All of the latches were evenly closed which I sometimes had to live with questionable latching if I knew the connector wouldn't be disturbed and not have anyone pulling on the cable. When I flipped open the latch, the pin slid out as easily as it had slid in! Although it might not be the "perfect" tool for dupont connectors but I didn't have one bad crimp in all of my test crimps. ## Features - Crimping Range: 0.08-0.5mm ² AWG 28-20,compatible with XH2.54/3.96,PH2.0,PX,KK254,JST,Molex,Dupont, D-SUB Terminal - 【Precise】Well-polished wire electrical discharge machining cutting jaw, which provides precise and accurate crimping without damage - 【Durable】Made of premium industrial grade high strength tool steel, with special surface treatment to achieves rust and corrosion resistance, strong enough for a long service life - 【Effortless】Smooth ratcheting mechanism and tension adjust knob save 50% effort, which is important for long time operation - 【Ergonomic】Slight angled head design and non-slip handle makes the operation comfortable and effortless,even in wet&oil condition.

It does crimp both male and female dsub pins. Quite nicely too. I would recommend having a couple of dsub pin extractor/insertion tools on hand when building the plugs... **Q: Can I use SN-2549 for bouth jst xh2.54 and jst ph2.0 ?** A: For perfect crimping, I suggest you to use SN-01BM for PH2.0 and SN-28B for XH2.54 **Q: Does this work with 2.8mm car motorcycle electrical connectors? https://www.amazon.com/dp/b075ldmnwk** A: I suggest yu to use SN-2549 or you can send image or technical data to me for confirmation . **Q: Will these work on jst-xh connectors for lipo battery balancer terminals?** A: Yes, it can work with JST-xh 2.50mm connectors. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality tool that works well. *by R***. on July 10, 2021* I use this tool for crimping JST XH pins.

But it's not really good for those. The die is not wide enough to encompass both the wire and insulation sections of the terminal at the same time. So either you get a good crimp on the insulation or on the wire, but not both. So then you have to shift the terminal and crimp again. This often results in the terminal being bent or otherwise deformed so it won't slide easily into the Molex housing. (Example: Molex housing p/n 22-01-3027) I gave it 4 stars because it's a really nice tool. It's slick. The ratchet and everything work really well. It's just not suitable for the KK 254 terminals. I returned it. I'm still in need of a crimper that works with those. ## Frequently Bought Together - iCrimp SN-01BM Ratchet Crimper AWG28-20 for XH2.54/3.96,PH2.0,PX,JST,Molex Terminal - Fermerry 22 AWG Stranded Wire Spool 25ft Each 6 Colors Flexible 22 Gauge Silicone Hook up Wire Kit Electrical Tinned Copper Wire - Taiss 560PCS 2.54mm JST-XH Connector Kit 2.54mm 2/3/4/5/6 Pin Housing Female and Male Adapter Cable Connector Plug,JST Connector Female Pin Head Connector Adapter Plug --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/38604224-sn-01bm](https://www.desertcart.com.au/products/38604224-sn-01bm) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-05-19*
