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 Ø12mm to Ø16mm,
and satisfies the need for small-size, light-weight
and high-density electronic components.
