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.

ELECTRICAL SPECIFICATIONS

Current Rating: 5 amps.

Test Voltage Between Contacts:

At sea level: 1800VRMS.

At 70,000 feet [21,336 meters]: 450VRMS.

Insulation Resistance: 5000 Megohm minimum at 500VDC

potential.

Contact Resistance: 30 millivolts maximum at rated current

(with gold plating).

Operating Temperature: - 55

°C to + 125°C.

Humidity: 96 hours at 90% relative humidity at + 40

°C, dried

at room temperature for 3 hours minimum, insulation

resistance 5000 Megohm.

Durability: (With gold plating.) After 500 cycles of insertion

and withdrawal of 0.070" [1.78mm] thick steel test gauge,

contact resistance less than 0.030V at 5 amps and individual

contact retention force when measured with a 0.054" [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 55cps at 0.06 double amplitude with

no loss of continuity.

APPLICATIONS

For use with 0.062" [1.57mm] printed circuit boards requiring

an edgeboard type connector on 0.156" [3.96mm] centers.
