Connectors for harsh vibrations and shocks
30 April 2019, Interconnection

Capable of withstanding a 10 G vibrational force for a period of 6 hours, the components in Harwin’s new M225 connector series are intended for industrial deployment.

These compact cable-to-board connectors feature a robust construction for prolonged operational lifespan, thanks to their glass-reinforced polyphenylene sulfide (PPS) enclosures, with a 100 MΩ minimum insulation resistance ensuring continued signal integrity.

They have a double-row contact arrangement with a 2 mm pitch – enabling mating of their through-board PCB male connectors to the corresponding female crimp connectors – with an array of different wire sizes (from #22 AWG to #28 AWG) being accommodated.

Each tin-plated copper alloy male contact has a current rating of 3,3 A (3,0 A when all contacts are electrically loaded simultaneously) and a maximum contact resistance of 25 m. When mated, the single-piece female contacts each have three surfaces touching the corresponding male pin. This means that reliable interconnection is maintained, even when placed in the most uncompromising of application settings and under extremely challenging working conditions.

A rapid mate-before-lock retention system has been developed to increase mated connector holding force and assist with vibration resilience. The female connector is fitted with rubber retainers, and locking pins are supplied loose. These pins are pushed into the rear of the mated female connector, and subsequently expand the rubber retainers to grip onto the male connector.

There are shrouded contacts on both the male and female connector elements to prevent damage, while polarised housings safeguard against the possibility of mismating. The female crimp contacts are available on reels (for high-volume automated production) or loose (for prototyping purposes), with a hand crimp tool offered for low-volume.

An operational temperature range of -55°C to +125°C is covered and a 50 mating cycle lifespan supported. These components are aimed at factory automation and processing machinery, industrial drives, robotics, test/monitoring instrumentation, handheld test equipment and industrial automation controls.
