M225 - Elevated Performance 2mm Pitch Industrial Connectors Equipped to Take on Heavy Vibrations & Shocks

Crimp contacts supplied in a carrier strip format to facilitate high volume automated assembly processes

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

These compact, high performance cable-to-board units feature a robust construction for prolonged operational lifespan, thanks to their glass-reinforced polyphenylene sulfide (PPS) enclosures, with a 100MΩ minimum insulation resistance ensuring continued signal integrity. They have a double row contact arrangement with a 2mm pitch – enabling mating of their through-board PCB male connectors to the corresponding female crimp connectors – with an array of different wire sizes (from 22AWG to 28AWG) being accommodated. Each tin-plated copper alloy male contact has a current rating of 3.3A (3.0A when all contacts are electrically loaded simultaneously) and a maximum contact resistance of 25mΩ. When mated, the single-piece female contacts each have 3 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, thereby preventing damage, while polarized housings safeguard against the possibility of mis-mating. 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.


Female connectors are suitable for 22 to 28AWG, depending on the crimp contact specified. Male connectors are vertical throughboard, with selected pin counts; 10, 20, 26, 34 or 50 pins. Additional features include:

  • Extremely durable industrial connector system – 10G vibration, 100G Shock
  • Capable of withstanding extremes of temperature; -55°C to +125°C
  • Fully shrouded and polarized housings
  • Mate-before-lock system with push-fit rubber bush and pin arrangement
  • 3.0A per contact at 25°C
