iMINI B: Miniature Metal-Shell Circular Connectors

The iMINI B is a miniature high-reliability connector that delivers a high-performance interconnect solution in a compact form factor. It is ideal for tight spaces that do not require an abundance of connections and is commonly used for data and power transmission.

The small metal shell connector showcases a 1" circular configuration with a 20 UNEF threaded coupling for exceptional performance in extreme operating conditions.

Durability

 The sealed electronic connector is waterproof rated to IP-67/68, UL-recognized, and suitable for harsh, explosive, and industrial environments due to the use of the following durable materials: 

  • Connector Interface Sealing O-Ring: Silicone
  • Contact Carrier: Rigid PVC
  • Contacts: CU Alloy, Gold Over Nickel Plating
  • Coupling Nut: Nickel Plated Brass or Stainless Steel
  • Jam Nut: Glass Filled PBT
  • Mounting Gasket: Neoprene
  • Panel Mount Housing: Nickel Plated Brass or Stainless Steel
  • Plug/Receptacle Housing: Glass Filled PBT

The overmolds vary based on the selected material for the cable jacket, but typically consist of PVC, TPE, PBT, or TPU.

 

Performance

 

 

The iMINI B is specifically engineered to deliver reliable, compact, and quick-turn connections in industrial equipment. Key features of the harsh environment miniature connector include:

  • Amperage Rating: Up to 9A
  • Configuration: Available in two, three, or seven pin counts.
  • Contacts: 20-22 AWG
  • Ingress Protection: IP67
  • MAX Cable Diameter: 0.44"
  • Overmold Length: 2" with strain relief
  • Voltage Rating (RMS): Up to 600V
  • Wire Size: #16 through #20

The wire/cable selection and overmold material can impact the overall max temperature rating of the assembly, ranging between -40 ºC and +105 ºC.

Behind the Design: Engineered for High‑Performance Miniaturization Applications

The iMINI B is a circular plastic connector with a bayonet quick-connect coupling. The specialized design offers the ultimate solution for high-performance applications where ruggedness and voltage accuracy are paramount.

Consisting of high-grade, glass-filled PET/PBT, the iMINI B passes UL 94VO specifications for flammability. The insert arrangements can vary from two to 14 positions, and the coupling rings are available in a wide variety of color options. The miniature high-reliability connector is highly compatible with similar industrial connector series, such as the Minifast Series by Turck and the Mini-Charge by Brad Harrison.

Choosing Between Connectors

When selecting an appropriate connector, product developers and engineers must understand the benefits of each connector to determine the option that best meets their specific application. Key considerations include:

  • EMI/RFI shielding needs
  • IP rating
  • Number of required circuits
  • Wire gauge (contact size)

iCONN Systems has developed a technical specification sheet to help engineers and product developers select the right variant for space-constrained, demanding applications.
