DPX ARINC 404 DPX DPXA Single Shell DPX DPXA connectors are one-piece shell miniature rack/panel connectors. The construction offers high strength and maximum utilization of insert area for contact arrangements accommodating up to 106 contacts. Shells are keystone-shaped for polar- ization. Operating temperature for the DPXA is ~54.2C to +125C (67F to +257F). DPXB Polarized ARINC Shell DPXB connectors are DPXA connectors with an ARINC B shell. Additional polarization is provided by three hexagonal polarizing posts. Rack and Pane! : Connectors DPX2 Two Gang DPX Series DPX2 connectors are the original two-gang versions af the DPX, and are made of the same materials and accommodate the same contact arrangements. Keystone shaped shells accommodate two DPX inserts with up to 212 contacts. The DPX2 has three polarizing posts with 99 polarizing positions. DPX2-A ARINC A Shell DPX2-A connectors are DPX2 connectors with an ARINC A shell. This shell type has the receptacle flange placed .344 (8.74) from the front of the engaging portion of the shell, and short aluminum alloy polarizing posts permit polarization before contacts engage. DPX2-34B DPX2-B ARINC B Shell DPX2-B connectors supersede the DPX2-A and have an ARINC B shell. This shell type has the on, DPX2-338 receptacle flange placed .060 (1.52) from the front of the engaging portion of the shell, and polarizing posts permit polarization before the shells engage. DPX3 Three Gang DPX Series DPX3 connectors are three-gang versions of the DPX, made of the same materials, and accommo- date the same contact arrangements. The three- gang version can therefore accommodate up to a total of 318 in the keystone shaped shells, with three polarizing posts that are capable of providing up to 99 polarizing positions. DPX4 - Four Gang DPX Series DPX4 connectors are four gang versions of the DPX, made of the same materials, and can accommodate four separate arrangements that can total up to 424 contacts. The DPX4 has three polarizing posts with 99 polarizing positions. DPX3-33 DPX4-33 DPX*MA LITTLE CAESAR Contact Assembly DPX*MA connectors are DPX connectors with the LITTLE CAESAR contact assembly for rear in- sertion, release, and extraction of crimp type con- tacts. Insertion requires no tool; extraction requires an expendable plastic tool. A hard dielectric, closed-entry socket insert has lead-in chamfers for positive mating of contacts. Contacts are crimpable with the M22501 tool. DPX*ME Environmental with LITTLE CAESAR Contact Assembly DPX*ME connectors are DPXMA connectors with environmental interfacial and grommet seals, and olive drab shell finish.
