This, the thinnest, 2.5mm pitch connector,

is 8.1mm in height after mounting and

3.8mm in width. It is designed to meet the

demand for the high-density connection of

internal wires to printed circuit boards. It is

compact, highly reliable and low in cost.

Note: 1. Tolerances are non-cumulative:

0.05mm for all centers.

2. Hole dimension differ according to the kind of PC board and piercing method. If PC boards made of hard material are used, the hole dimensions should

be larger. The dimensions above should serve as a guideline. Contact JST for details.

Note: 1. Contact JST for gold-plated products.

2. SEH-00( )T-P0.6L is low-insertion force type contact, for easier

insertion/withdrawal, which would be less resistant to the vibration.

The crimp height is different from the standard contact.
