Low Mating Force High Cycle, Bristle Brush Contacts
As mentioned in the Rectangular section of this publication, the
Amphenol Low Mating Force and Amphenol LRM Surface Mount
Connectors utilize the Bristle Brush contact design. The Brush or
B³ contact is made up of multiple strands of high tensile wire that are
bundled together. 70% to 90% reduction in mating/unmating forces is
achieved over conventional contacts, and the brush contact has proven
durability and long contact life. Hybrid Low Mating Force connectors can
be designed with combinations of brush and coax/twinax/power
contacts or fiber optic termini. LRM Surface Mount Connectors can also
be designed with combinations of contact styles.
Bristle Brush Contacts - Multiple Stands of
Wire are Bundled together to form a
“Brush-like” Contact
