M40 Circular P Series

M40 Circular P Series

Heavy drive applications


  • High current applications
  • Reliable contact technology
  • 360° EMC shielding

Power Connectors Size 1.5


The Smiths Connectors M40 series is qualified for heavy drive applications in mechanical engineering, tooling machines, robotics, mechatronics, printing, packaging, conveyors and marine. P Series features outstanding protection against electromagnetic interference through a full 360° screen shielding.


The adoption of crimp contacts allows for a consistent high quality connection and reduces the total installation time of the connector by minimizing the number of operations. Machined contacts feature a closed barrel design ideally suited for manual hand tools and support a wide range of wire termination cross sections.
