Edgeboard Connectors, Dual Readout
FEATURES
• 0.156" C-C x 0.140" 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 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.
