MIL-DTL-26482 8-33 8-Shell 3Pin High-Density Bayonet Circular Connector

MIL-DTL-26482 Connectors Specification

• Unique 8-33 Insert Pattern: The 8-33 arrangement features a distinct 3-pin layout that differs from the standard 8-3. This provides unique mechanical keying, ensuring that only the correct 8-33 plug can be mated with its corresponding receptacle to prevent system errors.
• High-Stability Bayonet Lock: Equipped with a quick-disconnect bayonet system, it requires only a 1/3 turn to achieve a 100% positive lock. This audible and tactile feedback ensures the connector remains coupled in high-vibration aerospace and tactical environments.
• Precision Gold-Plated Contacts: Each #20 contact is treated with high-grade gold plating to ensure low electrical resistance and maximum signal integrity. These contacts are rated for 500+ mating cycles, maintaining stable performance in sensitive communication circuits.
• Extreme Environmental Protection: Designed for 2026 industrial standards, the connector offers full IP67 waterproof sealing when mated. Its high-performance rubber inserts resist moisture, dust, and corrosive chemicals common in outdoor and field deployments.
• Full Industry Intermateability: Despite its unique layout, our 8-33 series remains 100% intermateable with all MIL-DTL-26482 Series I compliant brands, including Amphenol PT06-8-33, ITT Cannon KPT, and Souriau 851.

FAQ

Q1: Is the 8-33 connector compatible with a standard 8-3 receptacle?
A: No. While both have 3 pins, the 8-33 insert arrangement has a different pin layout. They are mechanically keyed differently to prevent cross-mating. Please verify your connector pattern before ordering.

Q2: Which part numbers are available for the 8-33 layout?
A: We stock all major configurations, including MS3116F 8-33P (Plug), MS3112E 8-33S (Square Flange Receptacle), and MS3114E 8-33P (Jam Nut Receptacle).

Q3: Does the 8-33 series meet modern 2026 RoHS standards?
A: Yes. For industrial and commercial applications, we offer RoHS compliant finishes such as Electroless Nickel and Black Anodized, replacing the traditional Olive Drab Cadmium.

Q4: What is the lead time for Sta Electronic's MIL-DTL-26482 8-33 connectors?
A: We maintain a significant inventory of standard shell size 8 components in our Shenzhen warehouse, offering rapid global shipping for most 8-33 configurations.
