LRM Surface Mount Connectors
with MIL-C-55302 Bristle Brush Contacts
Amphenol
high performance and high contact density in a
low insertion force PCB connector for today’s
integrated avionics packaging requirements.
Designed to meet the high density needs of today’s
integrated electronic modules, this surface mount
connector uses the Brush
proven in military avionics packages, is qualified to
MIL-C-55302, and is the consensus choice for inte-
grated avionics systems.
LRM Connector advantages include:
• Low mating and unmating forces
• Proven durability and long contact life
• Multiple points of contact provide superior
• Surface/straddle mount module connectors;
