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.
Features––––––––––––––––––––––––
• Compact and slim
This connector is designed to be compact and unusually thin.
It measures only 8.1mm (.319") high after mounting and is just
3.8mm (.150") wide.
• 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.
• Whisker prevention
The contact material is treated with a reflow process, and the
square post is copper-undercoated and tin/lead-plated for
whisker prevention.
• 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.
