ITT Cannon has recently added a new addition to its standard range of Cm3 connectors for small servo motors in applications such as industrial motion control, robotics, factory automation and material handling. The new low-profile Cm3 2x power connectors use one standard power connector to feed the motor (three power contacts plus one ground contact) plus an additional power connector (featuring four power contacts) for the two-way brake and two-way thermal sensor. Two further signal connectors (two times six contacts) are used for the encoder or resolver. The new design enables ITT Cannon to offer a wider range of options to its customers as standard Cm3 connectors featuring one power connector and two signal contacts do not have enough power for brake and thermal sensor power ratings.
Designed as a replacement for two circular connectors, new Cm3 2x power connectors provide maximum power in a minimum size package that is 50 per cent lighter than conventional circular connectors. The connectors can be installed quickly and at low cost thanks to simple harnessing and easy contact assembly without tools. Benefiting from only one housing for the two power and two signal connectors, Cm3 2x power connectors benefit from a maximum current of 10A at 80degC and a maximum voltage of 630V AC for the power connectors with a wire section of up to 1.0mm2. The signal connectors feature a maximum current of 3A at 80degC and a maximum voltage of 48V AC.
Cm3 2x power connectors feature crimp contacts, excellent vibration resistance and are completely shielded and sealed. Further technical details of the components include a contact resistance of less than 10mOhm, an insulation resistance of more than 5000Mohm, an operating temperature range of -40 up to +125degC and sealing to IP65 or IP67.
