connect to their appropriate pins on the connector.
Stampers select from two popular styles of connectors: a military-style round connector and a rectangular connector. Either way, the connector chosen must be robust and able to withstand the shocks and vibrations of the stamping environment.
To borrow a well-known phrase from the NASA Apollo Moon Missions,
“failure is not an option,” and to use it to describe the attitude within Eagle Bend Mfg.’s sensor program would be an understatement. MF
Note: Mike Williams and Ed Steinebach will describe their sensor program in more detail at a conference presentation at FABTECH 2014 in Atlanta, on Wednesday, November 12. Learn more and register to attend by visiting www.fabtechexpo.com.

Best practices requires stampers to cen- tralize sensor cables into one connector. Note here how Williams routes sensor- cable channels underneath the sensor connector box. The cables then enter the box and the individual sensor wires con- nect to their appropriate pins on the con- nector.
position. Cams, used for forming, pierc- ing, trimming, stud insertion and other operations, can tend to stick and not return to their neutral position when the die opens. Or, in some cases the cam may not arrive into its fully extend- ed position. In either case, the imple- mentation of sensors to monitor cam position has become a routine appli- cation in many shops. The photo (pg. 78) shows two separate cams moni- tored for their respective returns with one inductive proximity sensor per cam. Note how the sensor cables are immediately routed into channels.
Centralizing Cables is Non-Negotiable
The centralization of all sensor cables into one connector is a non- negotiable must in metalforming shops following best practices, and Eagle Bend Mfg. is no exception. Note in photo 6 how Williams routes sensor- cable channels underneath the sensor connector box. The cables then enter the box and the individual sensor wires
