Smiths Interconnect has re-launched HBB series of single-pole high power 300A and 500A circular connectors. These connectors are compact, lightweight and ruggedized heavy-duty connectors designed for use in all types of harsh environment applications, including electric motor drives, military ground vehicle turret systems, rail transport, and industrial applications. Aerco has now assembled the connectors and they are available with low MOQs and short lead-times.
The connectors will be available for the target markets of military and commercial aerospace, including UAVs, military and commercial ground vehicles, industrial and oil & gas. Applications include electric motor drives, turret systems, military communications, mobile weapons, radar, battery, and intelligent power management systems.
The series is rated for surge/inrush currents of 6 kA for the 300A and 10kA for the 500A for 1 sec, making it suitable for deployment in applications like induction motors and power converters. Safety protection in the system includes a safety interlock last make, first break with finger protection on pin and socket contacts.
The connectors feature the best electrical performance and high levels of shock and vibration immunity due to the use of Smiths Interconnect’s hyperboloid contact technology. The plugs and receptacles are gender-reversible, being available with either pin or socket contracts and they can be ordered with optional straight or right angle backshells. Accessories include crimp lugs, heat shrink boots and additional O-rings. Standard operational temperature range is -55°C to +150°C, voltage rating at sea level is 750vdc, and dielectric withstand voltage at sea level is 2250vdc.
