motion|grade - M40 Circular Connectors

The M40 circular connectors of our motion|grade series are recognized industry standard for combined signal and power transmission up to 75A. The metal connectors with 360° shielding are characterized by their durability and high vibration resistance.

Product features:

  • Waterproof according to protection class IP67 (min. 30min/1m) when mated

  • M40 screw locking according to market standard

  • Metal housing with optimal 360° shielding

  • 2 contact arrangements on a shell size of ⌀ 45mm

  • 6- and 8 pin for combined signal and power transmission

  • Both contact arrangements including protective earth contact (PE)

  • Current transmission up to 75A at 630V AC/DC

  • Turned contacts with wire cross-section 0.75-10mm² / AWG 20-8

  • Optional zinc plating increases corrosion resistance from 48h to min. 96h

  • Qualified according to ECBT2 UL / certificate number E224856

Motion|grade is ideally suited for encoder feedback in servo drives or electric motors, but is also used in industrial automation, heavy equipment and renewable energy applications.  The connection solutions are compatible with competitor products.

Frequently Asked Questions

The following products are required for a complete parts list:

  • Cable connector and counterpart of the opposite gender (coupling/device part)

  • Back Shell

  • Depending on the application: Protective cap

  • Crimp contacts

  • Hand crimping tool or pneumatic tool

If you have special requirements regarding the number of cable outlets or their diameter, we will be happy to check the realization of a special version on the basis of the cable datasheet.

Our motion|grade connectors come with a silver-colored metal housing as standard. Alternatively, we will check the color matching of the various components in the desired color for corresponding order quantities.

Our motion|grade connectors are approved with protection class IP67 and are therefore waterproof. The requirement of 30 minutes at a water depth of 1 m is only a minimum requirement. On request, we can test the tightness for special water depths and dwell times.
