Other Brush Contact Rectangular Connectors
LRM (Line Replaceable Modules)
AMPHENOL CONTINUES TO DEVELOP
INTERCONNECTS THAT MEET THE DEMANDS OF
THE AVIONICS INDUSTRY
Starting with the development of the B3 contact, incorpo-
rated into the low mating force PCB connectors, the LRM
line replaceable module followed as the avionics high
density rectangular interconnect solution. LRM intercon-
nects are combinations of module and backplane inserts,
in one bay, two bay, three bay or more configurations.
LRM products are used on major programs of aircraft and
military vehicles.
This page and the next briefly describe the LRM family of
connectors. For complete information please see
Amphenol® High Performance Line Replaceable Module
(LRM) Interconnects catalog, 12-037.*
The Brush contact has superior performance in LRM
interconnects due to its low mating force, stable electrical
performance and extended life. Other LRM features
include:
• Backplane versatility: available with through-hole solder
posts or with compliant pins for solderless applications
• Wide range of PCB/heat sink accommodations with
standard surface mount tails or flex termination
• Polarization keys - up to 4096 possible keying positions
• Superior intermittancy-free performance under vibration
• Dielectric withstanding voltage: Staggered grid and
GEN-X styles: 100 volts at sea level (due to the
incorporation of ESD shield)
• Temperature range: suitable for vapor phase soldering;
normal operating temp. is –65°C to +125°C
• Current rating: 3.0A derated to 1.5A typical (dependant
on loading)
STAGGERED GRID LRM CONNECTORS
180 Brush contacts in a Staggered Grid
module insert mounted to a PC Board
LRM CONNECTORS WITH STAGGERED GRID
• Provides higher contact density for high speed
integrated circuitry in SEM-E and custom form factors
• 180 contact insert pattern grid in 8 rows: 0.100 inch
spacing along the row with 0.050 inch between rows,
rows offset 0.050 inch
• Options include various shell designs to accommo-
date a wide range of PC board/heat sink combinations
• Solder tail, wire wrap or compliant contact availability
• Amphenol ESD (Electrostatic Discharge) protection:
Utilization of the Faraday Cage principal to shunt
electrostatic discharge events to the conductive enclo-
sure on which the connector is mounted, thus never
allowing the high voltage, high current discharge
event to reside on any contacts.
• Designed for level 2 (flight line) maintenance
• Provides routing channels for backplane
LRM CONNECTORS WITH STAGGERED GRID
AIRFLOW-THRU CONTACT PATTERN
• Accommodate standard B3 tails in staggered pattern,
but with increased spacing in the center, and also
provide more airflow cooling of inserts; for use with
wider boards, up to 0.425 inch
GEN-X GRID LRM CONNECTOR
LRM CONNECTORS WITH GEN-X GRID
• Even higher contact density than staggered grid and improved
electrical performance
• All the feature of the 180 contact pattern, including ESD protection
• Available in SEM-E and custom form factors
• 236 contact pattern grid in 8 rows: 0.075 inch spacing along the row
with 0.060 inch between rows, rows offset 0.0375 inch
