| 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. ELECTRICAL SPECIFICATIONS Current Rating: 5 amps. Test Voltage Between Contacts: At sea level: 1800 V RMS. At 70,000 feet [21,336 meters]: 450 V RMS. Insulation Resistance: 5000 Megohm minimum at 500 VDC potential. Contact Resistance: 30 millivolts maximum at rated current (with gold plating). Operating Temperature: - 55C to + 125C. Humidity: 96 hours at 90% relative humidity at + 40C, dried at room temperature for 3 hours minimum, insulation resistance 5000 Megohm. Durability: (With gold plating.) After 500 cycles of insertion and withdrawal of .070" [1.78mm] thick steel test gauge, contact resistance less than .030 V at 5 amps and individual contact retention force when measured with a .054" [1.37mm] thick steel test slug greater than 1/2 ounce. Shock: Three 50g shocks in each of 3 mutually perpendicular planes with no loss of continuity. Vibration: 2 hours in each of 3 mutually perpendicular planes, frequency sweep 10 to 55 cps at .06 double amplitude with no loss of continuity. APPLICATIONS For use with .062" [1.57mm] printed circuit boards requiring an edgeboard type connector on .156" [3.96mm] centers.
