Wall Mount Receptacle, 39 × #20 Socket, Shell 20, Solder Cup — MIL-DTL-26482 I

Specifications

Overview

The MS3110E20-39S is a MIL-DTL-26482 Series I wall mount receptacle in shell size 20 with insert arrangement 20-39, carrying 39 × #20 socket solder-cup contacts. Series I is the original solder-contact generation of 26482, developed as the miniature companion to MIL-DTL-5015: it steps down to size 20 contacts for smaller-gauge wire while keeping the bayonet quick-disconnect coupling.

Class E is the environmental, grommet seal. Series I classes are not interchangeable with Series II: a Series I MS3116F is a sealed solder plug with a cable clamp, and there is no direct 'F' class in Series II, where the equivalent letter position instead denotes plating. Front-release solder contacts in Series I also use different tooling from the rear-release crimp M39029 contacts of Series II.

Each #20 contact is rated 7.5 A at 20 °C, the connector is rated to 1,000 VAC RMS and the assembly operates from -55 °C to +125 °C with 5,000 MΩ minimum insulation resistance. Airoadcon supplies the same MIL part number, interchangeable with the Amphenol / ITT Cannon PT series built to the same standard.
