PT Series Overview

The PT Series miniature cylindrical connectors are based on the MIL-DTL-26482 Series I standard, providing a compact and rugged interconnect solution for demanding power and signal applications. These MIL-DTL-26482 circular connectors offer high-density contact layouts in a smaller shell size, making them a strong fit wherever panel space, weight, and reliability are all important design considerations.

PT Series connectors are designed to maintain performance under vibration, shock, moisture, and temperature cycling. The platform combines aluminum alloy shells, resilient inserts, and rear grommet sealing to help protect electrical integrity in harsh environments. Designers can select from solder, crimp, PCB, coaxial, thermocouple, and hermetic variants, allowing the PT Series to support standard industrial wiring as well as specialized signal and sensor interfaces.

These MIL-DTL-26482 circular connectors are also available in multiple shell styles and finishes, including traditional olive drab cadmium and RoHS-compliant options such as black zinc alloy, electroless nickel, gray zinc nickel, and anodic coatings. This flexibility allows the PT Series to support both legacy MIL-based designs and modern industrial equipment builds that require environmental compliance and long-term durability. As a versatile family of MIL-DTL-26482 circular connectors, PT Series supports a wide range of power and signal design needs.

Typical Applications

PT Series MIL-DTL-26482 circular connectors are used wherever engineers need a rugged, compact interconnect solution for combined power and signal in constrained spaces. Their miniature form factor, quick bayonet coupling, and dependable sealing make them well suited for equipment operating in demanding field and factory conditions. These MIL-DTL-26482 circular connectors are especially useful where compact size, serviceability, and environmental protection all matter.

• Factory automation and robotics – Motor drives, I/O modules, sensors, encoders, and control cabinets exposed to vibration and repeated service cycles.
• Industrial machinery and machine tools – Packaging systems, process equipment, and harsh-duty industrial machinery requiring compact, serviceable circular connectors.
• Rail and mass transit – Vehicle control electronics, braking systems, signaling equipment, and onboard diagnostics where shock, vibration, and contaminants are common.
• Energy and power systems – Gensets, power distribution equipment, switchgear, and auxiliary control panels in conventional and alternative energy installations.
• Instrumentation and monitoring – Data acquisition systems, portable test equipment, and field-deployed sensors that require compact, sealed interfaces.
• Communications and signaling – Industrial radios, traffic control systems, and mixed power and signal electronics using MIL-DTL-26482 circular connectors.
• Oil, gas, and petrochemical equipment – Skid systems, pumps, and control equipment requiring reliable sealing against dust, moisture, and process contaminants.

Because the PT Series offers a broad range of shell styles, insert arrangements, and contact options, it gives designers a flexible connector platform that can be used across multiple pieces of equipment while maintaining a consistent MIL-DTL-26482 circular connectors interface strategy.
