Amphenol 348 Series M81511 Connector

RELIABLE HIGH-DENSITY CONNECTORS
This Amphenol 348 Series M81511 connector provides reliability & high contact density. 348 Series is a commercial equivalent to MIL-C-81511, not qualified to MIL-C-81511, they accommodate a minimum of three circuits to a maximum of one hundred and fifty five circuits. The Amphenol 348 Series M81511 connector is available in two basic constructions: Long (Series I) & Standard (Series II). The Series I M81511 connector features 100% scoop-proof construction (potential contact damage minimized by recessed pins). The Series II M81511 connector are scoop-proof when pin contacts are specified in the receptacle shell only. Mil Spec connector part numbers begin M81511/. Amphenol Proprietary part numbers begin 348-.

Locked Retention Force 23* 12 3 17 10 20 20 3 23 15 16 25 4 23 25 12 30 5 23 25 Durability After 500 mating-unmating cycles at a maximum rate of 300 cycles per hour, connectors shall not show any damage detrimental to the operation of the connector.
Corrosion After salt spray testing per method 1001, condition B, MIL-STD-1344 connectors shall show no exposure of basis metal which will affect performance.
Fluid Immersion Unmated connectors shall be immersed fully in fluids specified in table. At least one connector must be immersed in each fluid type. After the immersion period and a drying period of 1 hour, the connectors must remain completely functional.
Fluids for fluid immersion - Connector Class E MIL-H-5606, MIL-L-23699
Thermal Shock Connectors shall remain completely functional after being subjected to the temperature extremes specified below:
Low Temperature –65°C (+ 0°/– 3°) High Temperature –150°C (+ 3°/– 0°) Test Condition* F Vibration Connectors shall undergo vibration testing per method 2005, test condition IV, MIL-STD-1344 in low and high temperature extremes of preceding table with all contacts connected in series, and a current flow of 100 milliamperes. There shall be no circuit interruption longer than 1 micro-second.
Physical Shock The application of 1/2 sine-wave transient shock impulses of 50 gravity units to 3 planes for 11 milli-seconds, with test voltage applied to series connected contacts, shall result in no discontinuity longer than 1 micro-second. Connectors shall not be damaged, parts shall not become loose.
Temperature Life Mated connectors shall perform satisfactorily after being subjected to ambient temperatures specified, per class for 1000 hrs.
EMI Shielding Effectiveness As measured in a triaxial EMI leakage tester, connector shells with grounding springs shall exhibit a radio frequency attenuation equal to or greater than the following:
Frequency (MHz) Leakage Atten. (db) 100 65 300 55 800 45 1000 45 |
