All connectors on MC0-500 have a IP67 seal or better when mated.
LV Connector🔗
The LV connector on MC0-500 is the LF13WBRB-20SD from HIROSE. When mated, this connector achieves an IPX7/IPX8 rating. The mating part is either LF13WBP-20P or LF13WBLP-20P; both come in crimp and solder varieties and support shielding. The provided harness follows the diagram below, which also includes pinout information for the LV connector. Refer to the HIROSE documentation for additional information.
The pinout is as follows:

Note
On engineering sample units, only 12V input is supported. Production models have support for 24-48V+.
Ethernet Connector🔗
The Ethernet connector on MC0-500 is 9-2367359-1 from TE. This connector and the associated hardware in MC0-500 are configured for 100BASE-T. When mated, this connector achieves IP6K9K sealing. At this time, the firmware interface is not implemented.
The recommended mating connector is 9-2367337, which is available in a variety of forms.
HV Connectors🔗
MC0-500 has five high-voltage connectors, all of which are PL00X-301 connectors from Amphenol Industrial. Each has its HVIL (High Voltage Interlock) daisy-chained internally, and a fault is detected if any connector is improperly seated.
To run MC0-500 at its maximum rated current, the mating part should be crimped with 70 mm2 or larger wire. When mated, this connector achieves an IP67 seal.
The mating parts are PL18X-301, PL28X-301, PL10X-301, and PL20X-301.
Grounding🔗
An M4x0.7x10 socket head cap screw is provided on the front of the enclosure, located above the low voltage connector.
Provide a continuous low impedance connection between MC0-500’s grounding point, chassis ground, and the motor’s ground.
