Automotive safety systems depend on components that function flawlessly after years of exposure to vibration, temperature cycling, humidity, and environmental stress.

Airbag initiators rely on precision resistance wire with tightly controlled electrical characteristics to ensure reliable deployment within milliseconds. Even minor variations in resistance or dimensional consistency can impact system performance.

Sigmund Cohn Corp. manufactures ultra-fine resistance wire and precision-fabricated components for automotive safety applications, combining tight dimensional tolerances with exceptional electrical consistency and manufacturing repeatability. Wire can be supplied to a specified electrical resistance value rather than a nominal diameter, which is how most initiator bridgewire is specified.
