Double-Pole BMC – Four Housing Sizes / Multiple Colors

Double-Pole BMC are available in four (4) housing sizes. Each Double-Pole BMC size is available in multiple colors. As a safety feature, each color has a specific mechanical key slot. This provides an intuitive visual cue and mechanical fail-safe, preventing cross-mating connectors. Therefore, This feature eliminates the potential hazard of mating devices of different voltages.

Each Housing Size Supports Multiple Contact (AMP) Options

Different housing/contact combinations provide a flexible means to deploy according to your specific requirements and help ensure connectors are mated correctly.

2-Pole BMC

BMC Overview

  • Double-Pole BMC connectors feature a durable one-piece thermal polycarbonate housing integrating stainless steel spring backplates to maintain consistent “contact force” between mated contacts, ensuring low resistance and high-electrical efficiency. The two sides of a Double-Pole BMC connector are identical.
  • This genderless connector can be flipped 180 degrees and mated with an identical housing.  This provides quick and easy assembly while reducing costs by eliminating the need to purchase, maintain and store different SKUs, simplifying critical inventory management.
  • The Double-Pole BMC series of connectors come in 4 housing sizes (Small, Medium-small, Medium, and Large) with each housing size supporting multiple electrical contacts (AMP) options.  Each of the 4 housing sizes is available in multiple colors, each with a specific mechanical key slot. This provides an intuitive visual cue and mechanical fail-safe, preventing cross-mating connectors and devices of different voltages.
  • All the connectors are UL-rated to 600 volts. Contacts are traditionally silver-plated to minimize electrical resistance while offering exceptional durability and reliability.
  • Please note all standard housings and contacts can be purchased separately or in combination sets.

FEATURES

  • Precision contact alignment & swiping provides high current throughput with minimal contact resistance.
  • Swiping action cleans contact surfaces during connection/disconnection.

This data header/column shows the current product offerings which may include male and female terminals, made from one or more of the following materials:

0 – Brass materials support connection temperatures of 110°C.  Unplated brass is often used in optimal environments and application conditions.

1 – Copper Alloy materials support connection temperatures of over 120°C depending on the type. Unplated Copper Alloy is more expensive but provides a higher range of operating temperatures and malleability.

2 – Phosphor Bronze materials support connection temperatures of 130°C. Phosphor bronze is used in applications where brass would normally be susceptible to corrosion, for example in subzero freezing environments or when ammonia is present.

3 –Beryllium copper exhibits a wide range of properties, including:

  • High electrical and thermal conductivity
  • Non-sparking and non-magnetic characteristics
  • High ductility and excellent formability with regard to forming, machining, and metalworking processes
  • Higher resistance to corrosion and oxidation than steel
  • Higher durability than most copper alloys (resists wear and galling)
  • Retention of properties in extremely low or extremely high temperatures
  • Suitability for precipitation-hardening operations

4 – Copper is a good conductor and is malleable. It is often used in combination with other materials such as stainless steel to achieve a greater operating temperature range while providing increased tensile strength and durability.

5 – Stainless Steel is usually used in combination with other materials such as copper to achieve an operating temperature range and good conductivity while maintaining tensile strength and durability. High fatigue strength—also known as endurance strength—making it suitable for heavy cyclic load applications

AWG / mm²

Wire size is usually measured in American wire gauge (AWG), a standard for non-ferrous wire conductor sizes. The term “gauge” refers to the wire’s diameter. The higher the gauge number, the smaller the diameter and the thinner the wire. As a rule, thicker wire carries more current because there is less electrical resistance over a given length.
