DF40
■Features
High contact reliability – Effective connection wipe of 0.45 mm
1. Higher density of the board-mounted components
Extremely small board mounting pattern and low above-
the-board profile makes the connectors ideally suited for
small device applications.
Shock-absorbing rib
2. Stacking height variation : 1.5mm to 4.0mm
3. High contact reliability
Despite connectors small size and low profile the contacts
provide strong contact forces and long contact wipe (0.45
mm), guaranteeing reliable electrical and mechanical
performance.
4. Large self-alignment distance
The connectors will self-align within 0.33 mm.
Interlock indentations
(for 10 to 50 positions)
5. Confirmation of the fully mated condition
Positive “click” sensation confirms correct insertion and
connection of all contacts.
Stacking Height variation
6. Built-in shock absorbing feature
The protrusions and indents in the insulator bodies protect
the connectors from failures when exposed to sudden
impact.
