Basic Questions to Determine Connector Requirements
• How many conductors (wires) and what are the
wire gauges (size)?
Smallest contact sizes available by Military Specifica-
tions:
SAE AS50151 - size 16
MIL-DTL-26482 - size 20
• What’s your working voltage requirement?
See catalog insert arrangement table
Catalog IC-4.........ACA-B and GT Series
Catalog IC-5.........AC and SAE AS50151
Catalog 12-070 .....PT Series
• Are you using your connector in a benign envi-
ronment or a harsh environment?
Harsh environment - will need gaskets, grommets
and/or glands for environmental sealing
• Do you want to Solder or Crimp your wires?
• Are you going cable to cable or cable to panel?
Cable plug to Cable receptacle use:
– Straight plug with Inline cable receptacle
– 90° Plug with Inline cable receptacl
e
Cable plug to Panel receptacle use:
– Straight plug with either a wall mount receptacle,
box mount receptacle, or jam nut receptacle
– 90° plug with either a wall mount receptacle, box
mount receptacle, or jam nut receptacle
• What’s your cable o
uter diameter (OD)? Or are
you using discrete wires?
• Do you have any material restrictions?
– RoHS requirement
– Stainless steel
– Aluminum
– Neoprene
– Silicon
– Viton
• What type of plating or finish is preferred?
Common platings or finishes:
– Olive drab cadmium
– Nickel
– Black zinc alloy
– Electroless nickel
– Anodic coating
– Gray ZnNi (Conductive)
• Will you need accessories?
– Cable clamp
– Bushing
– Protection caps (metal or plastic)
– Dummy receptacle
• Are you using an electrical or signal connector?
