The LMD Connector Series was designed by Amphe-

nol Pyle-National to provide flexibility in the assembly

of wire harnesses that are used in instrumentation and

avionic control environments. The modular design of

the LMD provides rack and panel or cable to cable

attachment.

LMD Modular Connectors

Design Features of LMD Connectors

• An LMD Connector is comprised of a housing,

modules and contacts - each ordered separately,

requiring assembly

• Lightweight housings are offered in two materials

• standard black thermoplastic

• high performance composite material for EMI

shielding

• white thermoplastic nylon material with increased

solvent resistance

• Four standard modules are available with the

following contact arrangements: 1 #8, 4 #16, 9 #20,

16 #22

• Modules are available in sealed and unsealed

versions

• Linear module design may be used for rack and

panel or cable to cable applications

• Bussing modules available to allow for a plurality of

circuit network configurations without extra

hardware

• Diode modules provide a current protection system

for avionic instrumentation packages and eliminate

the need for dedicated PC boards and other

hardware

• Miniature relay modules can be added which

eliminate the need for printed circuit boards and

hardware

LMD Benefits

• Reduces assembly and production costs

• Eliminates costly PC board and associated hardware

• Reduces inventory levels and associated costs

• Allows for a variety of circuit configurations

• Permits ease of circuit upgrading

• Facilitates equipment maintenance

Supplementing the LMD connector family, Amphenol/Pyle

National offers the LMS in-line splice connector; a low cost

interconnects that incorporates the LMD modules and contacts.

• Standard LMS splice connector - 3-piece assembly with

module removal tool access

• Tool-less splice connector - 3-piece assembly with a

push-button module release for easy module removal

• Two-piece bracket available for panel mounting

• Used in wire harness, instrument and equipment

terminations and test points
