I am told these are common 3D printer related applications. ZH is one of the smallest pitch types of through-hole JST connector.

Hozan P-707 will crimp larger JST contact types (2.5mm pitch and larger) better than the above two tools due to superior conductor crimping force.

Not as well made but for the significantly lower price, it could be forgiven. The PAD-11 costs quite a bit more than the PA-09 but is significantly better made, contacts won’t get stuck in it after crimping, and it handles the smallest GH/SH types. Some may be familiar with the PA-09 – an expensive, crappy tool also designed for mainly JST contacts. Pictured above a two of the best available. Unlike many other connector families where there isn’t much in the way of good generic/budget crimp tools, there are many generic crimp tools specifically designed for JST contacts. Some of these (particularly for PH/XH) are frequently seen on eBay second hand, and may be worth watching out for if you crimp a lot of these connectors, as they are an order of magnitude easier to use than even the best generic tools.įor more obscure types, no hand tool is offered, however JST do sell a hand frame (YRS-XXX) for mounting dies for their MKS-L applicator (used in the AP-K2N crimping machine), a very expensive solution, and the only option for production/mission critical applications. I have listed the part numbers for these where available. These are mostly made by the German contract crimp tool manufacturer Wezag GmbH, will crimp the associated contacts perfectly and to specification, but are all expensive. JST offer high quality hand crimp tools for their popular connector families. Most will find it more convenient to source from eBay, however note that this is an unlikely source of genuine parts. Most are stocked by Digi-Key (US) and Farnell (UK). Where I specify part numbers, I’m only doing so for genuine parts. Note that compatible connectors are made by other manufacturers. Many of which are referred to as “JST Connectors” in various circles. On this page I’ll cover the most popular connectors from Japan Solderless Terminal. In the vernacular sense, precisely which type of connector is being referred to depends on who is using the term and in what context. Applications often require rugged terminals and lower mating force to reduce operator fatigue during assembly and/or to withstand high-mating cycles.“JST Connector” is either shorthand for a connector manufacturer called Japan Solderless Terminal, or a vernacular term for a range of different type of wire to board connectors, which either are, or resemble designs from Japan Solderless Terminal. The pre-lubricated version can be mated up to 250 times and fit into standard Micro-Fit 3.0 Housings. Micro-Fit 3.0 RMF (Reduced Mating Force) Terminals are designed for applications needing lower engagement and disengagement forces or when the units are cycled frequently. For lower applied costs, OEMs often prefer a compliant pin connector over one that requires soldering. The Micro-Fit 3.0 CPI Header mates with Micro-Fit 3.0 Receptacle, allowing running changes as boards transition from solder to press-fit applications. The robust eye-of-the-needle design provides a reliable interface when recommended board layouts are followed. Micro-Fit 3.0 CPI (Compliant Pin) Connectors provide a compliant pin interface while maintaining all the features of the standard Micro-Fit 3.0 Connector. The TPA reduces terminal back-out by providing locking redundancy assemblers cannot insert the TPA unless terminal is properly inserted. The Micro-Fit TPA Connector Family helps prevent failure in end products by offering terminal position assurance (TPA). Doing so can cause damage to the connector and/or terminal and consume valuable labor time.

In hard-to-reach applications, such as drawers or fan assembly trays, connectors need to be mated and unmated without being seen. They allow mating misalignment (per product drawing). Micro-Fit 3.0 Blind-Mate Interface (BMI) Connectors are designed for blind-mating applications.

OEMs often need power connectors in space-constrained applications. The Micro-Fit Connector Family offers up to 8.5A with a 3.00mm pitch, delivering power in a compact package in wire-to-wire and wire-to-board configurations.
