1 SCOPE

1.1 Scope. This specication covers performance requirements for Glenair nanominiature connectors manufactured

in accordance with MIL-DTL-32139.

1.2 Description. Metal shell nanominiature connectors on .025 inch (0.64 mm) centers, with TwistPin contacts.

2 ORDER OF PRECEDENCE

2.1 Order of Precedence. In the event of a conict between the requirements of this specication and the references

cited herein, this document takes precedence. The requirements set forth in customer specications and Glenair

detail drawings shall take precedence over this document.

3.1 ELECTRICAL REQUIREMENTS

3.1.1 Insulation Resistance. 5,000 megohms minimum between any pair of contacts and any contact and the shell

when tested in accordance with EIA-364 Procedure 21. Test voltage 100 volts DC ±5%.

3.1.2 Dielectric Withstanding Voltage.

3.1.2.1 Dielectric Withstanding Voltage (sea level). 250 volts ac, rms 60 Hz. Connectors shall show no evidence of

breakdown or ashover when subjected to the DWV test of EIA-364 Procedure 20, test condition I.

3.1.2.2 Dielectric Withstanding Voltage (70,000 feet). 100 volts ac, rms 60 Hz. Connectors shall show no evidence of

breakdown or ashover when subjected to the DWV test of EIA-364 Procedure 20, test condition IV.

3.1.3 Contact Resistance

3.1.3.1 Contact Resistance. The voltage drop of a mated pair of contacts attached to wires shall not exceed 71 millivolt

drop maximum using a 1 ampere test current, when tested in accordance with EAI-364-06, using any catalog

supported wire types.

3.1.4 Low Signal Level Contact Resistance. When tested with a micro-ohmeter using a test current of 10 milliamperes

maximum, the resistance of a mated pair of contacts shall be 71 milliohms maximum using any catalog supported

wire types. Test procedure shall be in accordance with EIA-364-23.

3.1.5 Contact Current Capability. Contacts shall be capable of carrying 1.0 ampere in continuous duty operation from

-55° C to +125° C when tested in accordance with EIA-364-70.

3.1.6 Magnetic Permeability. Magnetic permeability, when tested in accordance with ASTM A342/A342M, shall not exceed

2 mu.

3.2 MECHANICAL REQUIREMENTS

3.2.1 Contact Engaging and Separation Force. Maximum engaging force shall be 5.0 ounces when tested in

accordance with MIL-DTL-32139. Minimum separation force shall be 0.4 ounces.

3.2.2 Connector Mating and Unmating Force. The maximum mating and unmating force shall not exceed a value

equal to 7 ounces times the number of contacts, when tested per MIL-DTL-32139. Mate connectors three times

before initial measurements are taken.

3.2.3 Contact Retention. Contacts, when tested in accordance with EIA-364-29, shall withstand a 2 pound axial load for

a minimum of 5 seconds.

3.2.4 Crimp Tensile Strength. Wire shall not break or pull out of crimp joints at an applied force of less than 1.0 pound

(0.44 kg) for 30 AWG wire, when tested in accordance with EIA-364-08. Wire breakage other than at the crimp shall

not constitute failure.

3.2.5 Resistance to Soldering Heat. There shall be no degradation of the plastic, bonding adhesives, or sealing

elastomers. Connector insulators shall also be capable of withstanding solder heat without evidence of

deteriorating, deforming, or change of physical dimensions in accordance with EIA-364-56.

3.2.6 Solderability. Printed circuit terminals shall meet the solderability requirements of MIL-STD-202 Method 208.

3.2. Durability. 200 mating and unmating cycles in accordance with test procedure EIA-364-09. Connectors shall show

no mechanical or electrical defects detrimental to the operation of the connector and shall subsequently pass Low

Level Contact Resistance, Shock, Vibration, Low Level Contact Resistance, and DWV in sequence

3.3 ENVIRONMENTAL REQUIREMENTS

3.3.1 Salt Spray (corrosion). Nickel-plated aluminum connectors shall show no exposure of base metal due to

corrosion when subjected to the salt spray test of EIA-364-26, condition B, with a 48 hour duration. In addition,

connectors shall meet, low signal level contact resistance and mating/unmating force requirements.

3.3.2 Fluid Immersion. Connectors shall meet mating force requirements following 20 hours immersion in synthetic

lubricating oil MIL-PRF-7808, 2 hours in Perchloroethylene cleaning solvent ASTM D4376, and 1 hour immersion

in coolant MIL-PRF-87252, when tested in accordance with MIL-DTL-32139. There shall be no degradation of the

plastic, bonding adhesives, or elastomers.

3.3.3 Thermal Vacuum Outgassing. Connector shall not exceed 1.0% total mass loss (TML) or 0.1% total volatile

condensible materials (VCM) when tested in accordance with ASTM E595.
