CRC (Compact Robotic Connectors) I/O Connectors

Molex CRC (Compact Robotic Connectors) I/O Connector System provides a compact solution for small industrial robotics and factory automation equipment. The shielded rectangular I/O connectors provide 7.0A to 15.0A of signal/power in up to 50-circuits. The panel-mount connectors feature a compact design that takes up approximately 1/15th the space of industry-standard duty connectors. Terminal housings can be easily snapped into panel-mount shells without any tools making field installation and maintenance fast and easy. Molex CRC Connectors are delivered in kit form for easy assembly and housings and shells can accept either male or female inserts for maximum design flexibility.
