Im looking around for decent quality connectors to use for the multiple

wires that go to the pitch and roll servos on my autopilot - all 22 or 20

awg wires.  After a few hours of intense brow furrowing, I finally started

making sense of the voluminous choices on the Mouser web site, but a few

questions remain.  I think I have it narrowed down to either the series 1

or series 2 AMP CPC connectors -  see



 http://www.mouser.com/catalog/626/957.pdf



Series 1 is described as having "size 16" contacts, while series 2 has

"size 20".  Not sure what that means - does it matter? Secondly, which (if

any) of the pins and sockets available for the series 1 or series 2

connectors can be crimped using my B&C d-sub crimping tool?



Could someone familiar with the AMP CPC connectors steer me in the right

direction?



thanks



Erich Weaver

Looks like the "size 16" contacts are larger than the "size 20" 
	


contacts.  Size 20 is described as "high density", meaning more pins per 

connector than "standard".  More pins per connector means they have to 

be smaller.  This translates to lower current carrying capacity in high 

density connector pins compared connector to standard pins.  This may 

not be a problem in an autopilot system, since the currents are not 

large (given the 20 and 22 awg wires involved).  You can find lots more 

information by wading through the AMP website, finding the right catalog 

section, etc.

Hard to tell without sifting through the appropriate AMP catalog.  I 
	


would be surprised if they were compatible with the d-sub tool (used 

mine this weekend...works great).  There are as many crimp tools out 

there as connector contact styles.  Few of them are cross compatible, 

and a compatible tool is required to produce good crimps.



Some basic questions:  Where in the autopilot system will these 

connectors be located?  Do you need connectors in the system in addition 

to the ones on the servos and controllers?  If additional connectors are 

required, why not use d-subs? (they are cheap, reliable, and you already 

have the crimp tool!!   )

Erich -

 

Buy the AMP CPC Type 2. Allied is a good source and they no longer have a

min. $ amount per order. 



Buy the gold plated pins size 20 pins from either Steinmark or B&C and the

crimper from B&C. Stein may also carry the crimper. We used this combo on

the CPC's for the panel and for the DB9's on the autopilot sevros and DB25

for the Tru Trak box itself. 



Piece of cake to get good crimps. The pins are good for 20 - 26 AWG and

although they are a bit more expensive, they are mil-spec and for avionics,

that is what is best.

 

Cheers,
