LMD’s module options provide a mix of both active and passive devices within one connector. The features and options of this series describe the design flexibility in this connector series: • LMD Standard components are molded of a U/L rated 94VO flame retardant, light-weight thermoplastic material. Alternate white nylon material (provides resistance to industrial oils and solvents) is available; consult Amphenol Aerospace for availability. • The linear LMD connector may be used for rack and panel or cable-to-cable applications. • Plug and receptacle housings may be front or rear panel mounted. • Optional keying post provides six position keying capability. • The optional center jackscrew provides ease of mating and unmating and insures high reliability under vibration. • Cable strain reliefs are available for internal attachment. (See page 107). • Variety of module types. Sealed and unsealed modules accept rear release #8, #16, #20 and #22 gauge contacts. Bussing, diode and relay modules available. PC tail contacts are also available; consult Amphenol Aerospace. • A variety of contacts accept #8 through #28 AWG wire. Commercially available automated crimp terminating equipment may be used. • Wired or unwired modules are rear inserted and held by two retention tines. With the aid of a front release tool, the modules are easily removed from the rear. (See pg. 107). • Pin or socket modules may be intermixed in plug or receptacle housings.
