The Backbone of Reliable System Builds

At Critical Systems, Inc. (CSI), precision, reliability, and repeatability are the foundation of every electrical harness and cable assembly we build. Whether we're engineering wiring for ultra-high purity gas delivery systems, semiconductor tools, or custom process assemblies, our electrical work is executed with uncompromising attention to detail. In industries where performance and safety are paramount, clean, consistent terminations are not just preferred—they're essential.

Every harness we produce begins with a meticulously developed schematic, ensuring that each wire and pin is placed with absolute accuracy. This level of documentation guides our technicians through exact routing, connection types, and placement, significantly reducing the risk of wiring errors and ensuring repeatability across production runs. Our commitment to precision helps our clients avoid costly downtime and maintain compliance with strict industry standards.

The connectors, pins, and terminations we use are chosen with application-specific precision. For example, signal lines may require gold-plated contacts to preserve signal integrity in sensitive environments, while power lines demand high-current-capable crimp terminals. We never substitute or generalize—every component is selected based on exacting performance requirements. Our team ensures each connector is paired with the proper backshell or plug configuration, whether for strain relief, EMI shielding, or environmental sealing.

But wire work at CSI goes beyond just tidy bundles and color-coded leads. Each termination is crimped using calibrated, connector-specific tooling, ensuring consistency and qualification with every connection. Our inventory of application-specific crimpers and dies supports a broad range of industry-standard connector families, allowing us to deliver highly specialized, compliant wiring solutions for any build.

We also take pride in the craftsmanship that happens after the crimp—from routing and bundling to custom labeling and final inspection, our team treats every cable as if it were destined for a mission-critical environment. Because in many cases, it is. Our customers span semiconductor manufacturing, pharmaceutical production, aerospace applications, and other sectors where electrical reliability can’t be compromised.

At CSI, we exceed industry expectations for electrical quality and process control. Our high-performance wire assemblies are engineered not only for functionality but for long-term durability in demanding environments. When precision matters, our clients trust CSI to deliver electrical systems that meet—and often surpass—the toughest performance requirements.
