Rectangular Connectors
MCE Series Plastic Shell Edgeboard Connectors
Plastic Shell Edge Board
Connectors
Designed for commercial
applications requiring
frequent disconnect and
connect, including data
recorders and computers.
Mother board connector
can be ordered to fit any
pattern on your circuit
board.
This new connector features
the proven twist pin contact
with precision contact align-
ment with extremely low
engaging forces.
Units are available with con-
tacts as few as 40 and as
many as 110. Wire sizes 28
through 24, any type of plat-
ing or color coding, any
kind of wire termination
including wire wrap — a
high degree of flexibility for
your military or commercial
application.
Two hexagonal polarizing
keys can provide up to 36
different key combinations
are supplied.

Technical & Performance Data — Twist Pin Plastic Shell Connectors
Electrical
Contact Resistance
— The average
mated contact resistance is 4 milliohms,
with a maximum value of 8 milliohms,
using standard 24 AWG solid copper
leads when measured directly behind the
crimp joints of the mated pin and socket
contacts. The average resistance value at
100 microvolts is 4.8 milliohms.
Dielectric Withstanding
Voltage
— 800 VAC RMS at sea level
(600 for solder pots); 200 VAC RMS at
70,000 feet [21,336m] (150 for solder
pots).
Corrosion Resistance (Per MIL-
STD-202C, Method 101B, Condition
B)
— Both mated and unmated samples
do not exceed the maximum allowable
contact resistance (8 milliohms) when
subjected to the 48 hour salt spray test.
Durability
— The contact resistance
after 500 mating cycles is less than the
maximum allowable, 8 milliohms.
Insulation Resistance
— Greater than
5,000 megohms at room temperature.
Maximum Current Carrying
Capacity
— No. 24 contact 3 amperes.
It must be recognized however, that all the
wires to a connector will not carry their
maximum current under all environmen-
tal conditions due to wire temperature.
Rectangular
Connectors
Materials
Insulator
— Liquid Crystal Polymer
(LCP) per ASTM D5138 or
Polyphenylene Sulfide per
MIL-M-24519.
Contacts
— Pin-contact: Copper alloy
and beryllium copper alloy make up the
complete construction. Socket contact:
Copper alloy.
Hardware
—
Corrosion resistant
stainless steel.
Mechanical
Contact Engaging & Separation
Forces
— 8.0 oz. max. [2.24N] (eng.),
0.5 oz. min.[.14N] (sep.)
Finishes
Insulator
— None.
Contacts
— Standard finish is
0.000050 [0.00127] gold over copper
flash per MIL-G-45204, Type II.
Hardware
— Passivated per QQ-P-35.
Environmental
Temperature Range (Operating)
—
-67°F to 257°F [-55° C to +125°C].
Vibration (Per MIL-STD-202C,
Method 204A, Condition D)
— No
discontinuity in excess of 1 µ sec. dur-
ing twelve 20 minute sweeps from 10 to
2000 CPS at .06 double amplitude or 20
G forces, whichever is less.
