What does pH XH SM and so on in the pH terminal wire harness mean?
We noticed that different connectors have letters and numbers in their names, so what do the types of connectors such as PH, XH, SM mean? Xiamen Yihetai Cable Co., Ltd. is here to popularize the basic knowledge of the terminal wire industry.
Terminals PH, XH, SM, etc. are a series of connector part numbers of different types and spacings produced by JST (Japan Solderless Terminal Japan Crimp Terminal Manufacturing Co., Ltd.), because JST company uses the most, many domestic manufacturers are in Referring to the industry leader JST, most of them have such code names, and add PH, XH, SM and other codes after the name of their products, the purpose is to make it easier for the selectors to know the matching with JST and what series the positioning is. products, so this naming method has also become a common usage in the industry.

Each code name is a series of products, and the big difference between them is that the pitch (spacing) is different.
The general spacing of FH is 0.5mm
SH general spacing is 1.0mm
GH general spacing is 1.25mm
ZH The general spacing is 1.5mm
PH general spacing is 2.0mm
The general spacing of EH/XH is 2.5/2.54mm
The general pitch of VH is 3.96mm...

The difference between the terminal line model VH .EH.XH.PH:
1. The terminal line spacing is different: the general spacing of XH EH is 2.5mm. PH? The general spacing is 2.00mm. ZH The general spacing is 1.5mm. The general pitch of VH is 3.96mm.
2. Different functional categories: VH is a safety terminal, EH is a test terminal, XH is a ground terminal, and PH is a double-layer terminal.
The significance of the terminal wire model: it is convenient for the terminal wire customer to search for the specific model and product they want; it is convenient for the manufacturer to manage; at the same time, it saves the time and space occupied by the physical terminal wire.

1, the distance is different
a. PH: The distance between the terminal pin and the pin is 2.00 mm.
b. Eh: Eh indicates that the distance between the terminal pin and the pin is 2.50 mm.
c. XH: The distance between the terminal pin and the pin is 2.50 mm.
d. Zh: The distance between the terminal pin and the pin is 1.50 mm.
2. Different materials
a. PH: The material of PH is metallic phosphor bronze.
b. Eh: The material of Eh is metal tin.
c. XH: The material of XH is metal tin.
d. Zh: Zh material is PA66UL94V-2 resin.
