Vishay Dale
Edgeboard Connectors, Single Readout
FEATURES
• 0.156" [3.96mm] C-C.
• 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 0.054" - 0.071"
[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.
