MIL-DTL-26482 Series I Connectors

MIL-DTL-26482 Series I Connectors | Metabee

Introduction

MIL-DTL-26482 Series 1 connectors are miniature quick-disconnect circular electrical connectors featuring a reliable three-point bayonet coupling system. They use resilient inserts and sealing gaskets, with hermetically sealed versions featuring glass-to-metal seals also available.

Series 1 connectors use solder contacts, which are designed for wire termination by soldering. This provides a reliable and permanent termination method, making them well suited for applications where connectors are expected to remain in service for extended periods without frequent field replacement. Typical part numbers include MS3110, MS3111, MS3112, MS3114, MS3116, and MS3118. As a result, they are widely used in avionics subsystems, ground support equipment, shipboard electronics, and industrial machinery.

Features

Solder termination for signal and power contacts
3-Point Bayonet Coupling for quick and secure mating and unmating
Rear-release contact retention in most configurations
Available in both plug and receptacle configurations, including wall-mount, jam nut, and solder-mount receptacles
Shell sizes ranging from 8 to 20, with multiple insert arrangements per size

Order Reference

Ordering a MIL-DTL-26482 connector can be daunting due to the complex alphanumeric codes. Here is how to break down a typical part number like MS3116F14-19S.

1. Prefix (MS): Indicates Military Standard. Brands may use their own (PT, 851, KPT).

2. Shell Style (3116):

3110 / 3470: Wall mount receptacle.
3111 / 3471: Cable connecting receptacle.
3112 / 3472: Box mount receptacle.
3116 / 3476: Straight plug.

3. Service Class (F): Indicates environmental resistance and fluid resistance.

4. Shell Size (14): The diameter of the connector shell. Sizes range from 8 to 24.

5. Insert Arrangement (14-19): This is the layout of the pins. In this case, 14 refers to the shell size, and 19 indicates the specific layout (which happens to have 19 contacts).

6. Insert Rotation (W, X, Y, Z): These letters indicate a specialized keying position.

7. Contact Gender (S): P for Pin (Male) and S for Socket (Female).

8. The following is the part number specification for Metabee MIL-DTL-26482 Series I Connectors:
