New, HBB High Power Circular Connectors from Smiths Interconnect – now assembled by Aerco Ltd
EAO Series 82 Pushbuttons – Enhanced protection. Fast mounting.
IP67 front and rear sealed 316L Stainless steel Pushbuttons with integrated M12 connector. The expert partner for innovative, intuitive and reliable Human Machine Interfaces (HMIs), has extended the robust and attractive Series 82 with an overmoulded option and M12 connector. The new 22mm mounted version in food grade stainless steel is offers fast mounting as well as complete front and rear IP67 protection.
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.

It is common to expose actuators and indicators to extremely harsh operating conditions. For example in the food & beverage industry, where alkaline cleaning agents and corrosion severely affect HMIs. In addition, external factors in the form of hard-to-re- move dirt, fine dust, along with severe vibrations and blunt impacts commonly encoun- tered in heavy duty and special vehicles applications also require HMIs to offer a very high level of resistance. Typical applications • Food and beverage industry • Heavy duty & special vehicles • Buses and coaches • Marine applications
Series 82 pushbutton showing integrated M12 connector
The overmoulded version of the Series 82 is capable of meeting these strict require- ments offering reliable enhanced protection. These attractively designed illuminated pushbuttons feature a housing made from SUS 316L stainless steel and a Tritan light guide resistant to cleaning agents. These design features provide protection against wear and ensure consistent clarity of both the dot and the ring illumination. Advantages of the overmoulded version • Complete IP67 protection for illuminated pushbuttons • Tritan light guide resistant to cleaning agents • Housing made of SUS 316L stainless steel • High resistance to vibration and impact • M12 connector for fast and resilient mounting • 24VDC illuminated versions available with red, green, white or blue LEDs
The switches utilise a robust M12 connector. This connection method saves customers
time when it comes to mounting as well as enabling a highly resilient HMI connection. The rear of the device is also IP67-compliant thanks to the overmoulding of the switch and connector, ensuring that the HMI has complete and reliable protection. The overmoulded version also offers very high resistance to vibrations and impact.
