ITT Introduces New Connector for Medium and Large Servomotors

ITT Electronic Components has developed a new connector for medium and large servomotors that provides design engineers with a space-saving and flexible connector capable of handling up to 40A. The low-profile Cm5™ connector is designed for servomotors with a flange size less than 150mm2, offering simplified internal wiring and replacing two bulkier conventional circular connectors.

The low-profile Cm5 connector is 50% smaller and lighter than conventional circular connector designs and provides a high degree of vibration and shock resistance, making it well-suited for industrial and other harsh environment applications. The connector is completely sealed and shielded for high reliability, and its simple harnessing reduces assembly and installation time in motor applications. The Cm5 connectors feature IP67 sealing, a housing with one power and up to 24 feedback insulators, each with four or six signal contacts, separated by metal shielded walls, two sealed entries for power and feedback cables and a first-make/last-break power ground contact electrically linked to the shell.

The Cm5 connector meets all requirements for DIN EN61984 safety compliance and has a 60V signal rating, operating voltage of up to 640V, and current ratings of 3A for signal and 40A for power. A zinc die cast shell, Fluor rubber sealing parts, high temperature insulator material and high quality contacts ensure a rugged, reliable design. Servomotor applications enhanced by the Cm5 connector include machine tools, packaging, factory automation, food packaging, assembly lines, marking and labeling, robotics, production machines and laser trimming systems. The Cm5 connector is part of ITT's CmX Series of connectors, which will be introduced in a number of sizes compatible with the various flange diameters and power requirements of servomotors currently on the market and in development.

For quantities of 10,000 pieces or more, pricing is typically $20 to $25 per unit. The Cm5 is also available with high-vibration resistant socket contacts at a premium. Lead times start at three weeks.
