Model EB7D
Vishay Dale
Edgeboard Connectors
Dual Readout
FEATURES
• .156" C-C x .140" grid [3.96mm x 3.56mm].
• Bifurcated bellows contacts provide 2 flexing contact surfaces
to assure positive contact under adverse conditions such as
vibration or PC board irregularities.
• Accepts PC board thickness of .054" - .071" [1.37mm -
1.80mm].
• Polarization between contact positions in all sizes.
Between contact polarization permits polarizing without loss of
a contact position.
• Selective gold plating.
• Polarizing key is reinforced nylon, may be inserted by hand,
requires no adhesive.
• Protected entry, provided by recessed leading edge of contact,
permits the card slot to straighten and align the board before
electrical contact is made. Prevents damage to contact which
might be caused by warped or out of tolerance boards.
•
Recognized under the Component Program of
Underwriters Laboratories, Inc. Listed under File E65524,
Project 77CH3889.
