ABB Circular Connectors: Exceeding VG95234 Standards for
Versatile and Rugged Applications The ABB range from TT Electronics AB Connectors Ltd, are Bayonet Lock Connectors that are manufactured to meet the prestigious VG 95234 military standard.

ased on the long standing Mil-C-5015 specification, the ABB range stands out by meeting all the performance criteria of the Mil-C-5015 standard while enhancing security through a reverse bayonet locking mechanism. This design improvement ensures identical panel mounting dimensions and contact layouts with corresponding MS types, making it an appropriate choice for users looking for environmental protection and robust performance.
The connectors feature exceptional environmental protection, achieved through a dynamic seal under the coupling nut and individual wire sealing grommets in the rear accessory assembly. Additionally, a wavy washer under the coupling nut ensures shell-to-shell continuity. This, combined with a variety of back shells, provides high levels of electromagnetic interference (EMI) and radio frequency interference (RFI) screening, crucial for maintaining signal integrity in demanding environments. The current demand for VG 95234 connectors is significantly driven by the British Forces’ new Mechanised Infantry Vehicle (MIV), the Boxer. Developed through a partnership between UK-based BAE and German-based Rheinmetall, the Boxer is an all-terrain, eight-by-eight wheeled armoured transport vehicle designed for modern combat. The rugged performance of ABB connectors makes them ideal for such military applications, as they are built to withstand the harsh conditions encountered in various ground vehicle programs. Beyond military applications, VG 95234 connectors are extensively used in heavy

and off-road vehicles, rail track and rolling stock, oil and gas industries, factory automation and robotics. This versatility highlights the connectors’ adaptability to different industrial requirements, providing reliable performance in a wide range of environments.
The connectors meet the stringent requirements of BS9522 F0032 and VG95234 standards, ensuring they are suitable for demanding applications. They operate within a temperature range of -55°C to +125°C, with the high-temperature version, HTABB, extending this range to +190°C due to its fluorocarbon insulator.
