New, HBB High Power Circular Connectors from Smiths Interconnect – now assembled by Aerco Ltd


Secure and safe wire to wire waterproof connections


When waterproofing is a consideration for reliably connecting wires, the IPX7 rating afforded by the use of solid rubber seal rings is a proven method. The 2mm pitch E-tec range allows 2, 3 or 4 wires to be plugged and unplugged. These are held securely with an inner housing lock. The sprung construction of the phosphor bronze contact receptacle and mating plug deliver a reliable 3A rating for wires AWG #22 to #26. This connector system can be supplied


incorporated in a complete cable assembly terminated to customer requirements. A summary of the range is available to download or view here.

Lattice Expands mVision Solutions Stack Capabilities


Ruggedized High Performance Circular Power Connectors for Harsh Environments. The newly re-launched HBB series of single pole high power 300A and 500A circular


connectors from Smiths Interconnect offer a compact, lightweight and ruggedized heavy duty connector designed for use in all types of harsh environment applications, including electric vehicle drive systems, rail transport and industrial applications. Now assembled by Aerco, they are available with no MOQ and two week lead-times. Available in a RoHs compliant Black Zinc Nickel finish, the durable HBB delivers a more


efficient, higher current transmission in a more compact and lighter connector compared to similar sized 38999 style products and has a superior endurance of 5000 mating cycles. Meeting design SWaP goals of high power within a small size and minimal weight interconnect solution, the 300A connector is achieved in a size 17 shell and the 500A connector in a size 21 shell, with current specified at 100°C. The robust aluminium shell is available in three different shell polarizations, fully sealed to IPx7 ingress protection and featuring 360° EMI/RFI shielding via a customer serviceable conductive ‘O’ ring, which is fitted as standard to receptacles. The HBB 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.


The connectors assemble using a straight push on procedure to fully mate with a traditional quick release bayonet un-mating mechanism, resulting in a minimal axial force required to assemble and separate with zero applied mating torque. The tactile ‘push mate’ mating provides confirmation of a full mate preventing “attached not locked” condition. The design facilitates easy mating and un-mating while near to neighbouring devices, supporting applications where higher density packing is required in space constrained environments. Safety protection includes finger protection on pin and socket contacts. With performance similar to the MIL-DTL-5015 specification for heavy-duty circular


electrical connectors for harsh environments, 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 ultra-low resistance and smooth and light wiping action of the hyperboloid contacts results in low fretting fatigue/corrosion and long contact life with minimal degradation in performance. The three dimensional symmetry of the hyperboloid contact design ensures this high degree of immunity to shock and vibration, guaranteeing electrical continuity in all circumstances. Contact resistance figures as low as 0.05mΩ keeps resistive losses and generated heat at a minimal, facilitating maximum transmission performance. The plugs and receptacles are gender reversible, available with either pin or socket contacts, and they can be ordered with optional straight or right angle back shells. Accessories include crimp lugs, heat shrink boots and additional O-rings. Standard operational temperature range is -55°C to +150°C and voltage rating at sea


level is 750vdc. Target markets include military and commercial aerospace, military and commercial


land vehicles and general industrial. Applications include electric motor drives, turret systems, military communications, radar and power management/distribution systems.

Uprated LinkSwitch AC-DC Converter ICs from Power Integrations Increase Available Current by 60%


High-efficiency LNK3207 ICs reduce BOM count and simplify buck converter design for appliances, sensors and metering applications Power Integrations (Nasdaq: POWI), the leader in high- voltage integrated circuits for energy-efficient power conversion, today announced a new member of its acclaimed LinkSwitch™-TN2 AC-DC converter family. The new LNK3207 ICs facilitate higher-power offline buck converter designs for appliances and industrial applications by increasing the available output current from 360 mA to 575 mA, while also reducing BOM count. Silvestro Fimiani, product marketing manager at Power Integrations said: “These new


LinkSwitch-TN2 ICs are pin-to-pin compatible with previous generations, making it simple for customers to upgrade to higher-power designs. A high-current buck converter can be created using a minimal number of easily available components while saving at least one diode over previous solutions.”
