High Performance Miniature Circular Connectors HR12 Series Features Snap lock allows for easy insertion and extraction and prevents the accidental un-mating of the connector due to vibration or impact. The plug diameter range from 12mm to 16mm, and satisfies the need for small-size, light-weight and high-density electronic components. Equipped with internal metal parts and a shielding mechanism, the HR12 (20-contacts) and HR212 feature enhanced protection against EMI.
