Aerospace/defense sealing guide available

A quick–reference guide from Bal Seal Engineering Inc., Foothill Ranch, Calif., provides information about sealing, connecting, conducting and EMI/RFI shielding solutions for aerospace and defense equipment.

Using images of military and commercial devices, the four-page “TMB-11” describes how Bal Seal’s Canted Coil Spring is used as a seal energizer or stand-alone electrical-mechanical component to improve equipment performance and reliability.

The Canted Coil Spring, a currentcarrying, locking, latching and holding component, can maintain a nearly constant force over a broad compression range, compensating for large mating tolerances and temperature changes without significant deviation from its initial force. Each coil in the spring works independently, maintaining contact with the mating surface and ensuring maximum conductivity. It allows designers to engineer specific insertion and breakaway forces, and also functions as an EMI/RFI shielding and grounding element.

The TMB-11 uses detailed insets and labels to provide a look at where and how products work in aerospace and defense equipment. Applications include UAV actuators, optoelectronics gimbals, or “pods,” hydraulic systems, solar arrays, and others.
