CONNECTOR
Disconnectable Crimp style connectors
• Compact and slim
3.8mm (.150") wide.
Radial Tape
2.5mm
(.098") pitch
Features ––––––––––––––––––––––––
This connector is designed to be compact and unusually thin.
It measures only 8.1mm (.319") high after mounting and is just
• Highly reliable contact
The contact has long dimples near the center that ensure
continuity of low voltage and low current circuits at all times,
even under conditions of vibration and abusive prying.
• Polarizing guides
The header and housing have guides to prevent improper
mating.
• Easy and effective crimping
Although the contact is compact, it has a long wire strip length,
2.6±0.4mm (.102"±.016"). This long length is very useful for
automatic crimping and when crimping shielded wires.
This, the thinnest, 2.5mm (.098") pitch
connector, is 8.1mm (.319") in height after
mounting and 3.8mm (.150") 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. Contact JST for gold-plated contacts.
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.
