After 500 cycles of insertion to + 125C. ive humidity at + 40C, and withdrawal of .070" [1.78mm] thick steel test gauge, contact resistance less than .030 V at 5 amps and individual contact retention force .054" [1.37mm] thick steel test slug greater than 1/2 ounce. when measured with a Shock: Three 50 G 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. PHYSICAL SPECIFICATIONS Contact Type: Bifurcated bellow Number of Contacts: 6, 10, 12, Ss. 15, 18 and 22 per side. Contact Spacing: .156" [3.96mm] center to center. Card Thickness: .054" to .071" [1.37mm to 1.80mm]. Card Slot Depth: Single Readout = .300" [7.62mm]. FEATURES * 156" [3.96mm] C-C VISHAY DALE, * 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. APPLICATIONS For use with .062" (1.57mm] printed circuit boards requiring an edgeboard type connector on .156" [3.96mm] centers.
