ITT’s Cannon and Veam connectors have been delivering the ultimate flexibility, performance and durability to a vast array of markets. The company has been making a difference all across the world by empowering key industries, enhancing transportation comfort and safety, connecting people with each other and to data and securing essential infrastructure.

The Veam connectors of ITT typically support power and data communications under train cars support critical signals with the help of reliable vibration resistant connectivity, which is enabled by compact solutions suiting high-density wiring environments.

Let’s now understand in detail the several types, features and utilities of Veam and other ITT connectors.

What is a Veam Connector?

ITT Veam CIR connectors make use of a quick-disconnect/positive-lock bayonet coupling mechanism for providing high shock and vibration resistance without using lock wires. These connectors, rated for 2,000 couplings at minimum, are known for their versatility. They offer a full range of accessories and back shells with the ability to accommodate up to 159 stamped, solder contacts, PCB, fibre-optic termini or high-speed data contacts.

The connectors can also have specifications with various inserts to fulfil zero-halogen/low-smoke needs and provide greater resistance to solvents, fuel oils and increased temperatures.

Different Types of Veam and Cannon Connectors

1.   Push-pull Circular Connectors

➢       Features

These connectors feature a spring-action cylindrical sleeve within or surrounding the integral connector housing that latches itself when the connector is pushed into its position. The connection releases through a rotate-and-pull, squeeze-and-pull or any other specific unlocking action preventing accidental disconnection.

A push-pull circular Veam connector is available in multiple voltages, sizes, and pin counts and in triaxial, coaxial, pneumatic and fluidic configurations.

➢       Utilities

  • Medical Purposes: Push-pull circular connectors are usually used in the medical market. Due to their versatility, dependability and user-friendliness, these connectors are used in the healthcare sector to connect stationary equipment and handheld devices.
  • Industrial Sector: Robotics, automation controls.
  • A/V: Broadcast equipment, event writing.
  • Test and Measurement: Test equipment, analysers.
  • Automotive: Diagnostic and production equipment.
  • Communications: Radar, antennas, radio equipment.
  • Transportation: Rail signalling, monitoring and control systems.
  • Military/Aerospace: Portable devices, soldier-worn equipment.

2.   ITT Cannon’s BKA ARINC 600 Rack and Panel Connectors

  • Features

These highly-engineered blind mate interconnects are available in 3 and 6 gang configurations and can accommodate a total of up to 800 low insertion force contacts, including the multi-signal Quadrax Contact Systems. These inserts are field replaceable, and the BKA connectors are available both in environmental and non-environmental versions. The Size 22 Stamped PCB Contacts for the BKA ARINC 600 Receptacles are available too, which save customers significant costs than traditional machined contacts.

  • Utilities
  • Commercial air transportation markets
  • MIlitary air transportation markets
