Environmentally sealed 250 VDC rated rectangular connectors deliver operational integrity

09 December 2020

Bulgin has announced a new range of Rectangular Power Connectors including 2, 3, 4, 6, 8 and 12 pole versions, intended for demanding cable-to-cable applications.

With a high current rating (13A), these connectors have a robust construction that ensures continued reliability in harsh operational environments. Thanks to their silicone rubber seals, these connectors fully conform to IP68 and IP69K standards, offering protection against the ingress of water, dust, etc. Compliance with EN60068-2-52 means they can be used in marine deployments too.

These connectorsmouldings consist of polybutylene terephthalate with polyamide glass fibre reinforcements embedded. Their contacts are made of copper alloy, with either nickel or gold plating specified. 14AGW to 20AWG diameter wires can be accommodated. A variety of optional added features are available for the Bulgin connectors. These include enhanced seal retention capabilities, protective end caps, shrink boot adapters, welded flanges and terminating resistors. Y-type connector terminations are also offered, to address automotive implementations.

Support from 100 mating cycles further underlines the durability of these new Bulgin connectors, covering an operational temperature range of -40°C to +120°C. Wedge-locks are supplied for greater contact retention, resulting in the ability to withstand forces of 111N. An insulation resistance of over 1000MO (at 500VDC) prevents leakage current issues.
