Our Products #4977203

The wiring harness of choice among the world's leading airlines. Open bundle harnesses are inherently easier to maintain because the wires, connectors and backshells are not covered by any external covering or coating. Used in engines, engine nacelles, and inside aircraft hulls.

The optimal wiring solution for installations in hostile environments. Closed bundle harnesses use a variety of different materials such as Nomex, PEEK, nylon and metal braiding to cover the bundles of wires inside. While slightly more difficult to service, this added protection makes the harnesses considerably more durable. Used in turbine engine hot sections, military applications and industrial applications, among others.

When strength matters. Overmold wiring harnesses are generally either open bundle or closed bundle harnesses that have molded joints to prevent separation or fatigue. These joints are molded over the wiring harness to provide an added measure of strength without significantly increasing cost. Used in aircraft wiring, engine harnesses, industrial applications and more.

Unisons innovative technology offers thermal management solutions with broad installation flexibility. Our conformal surface heat exchanger utilizes integrated fins, improving performance over brazed designs, is lower in weight, and with its surface mount design, greatly reduces air flow constriction as compared to traditional radiator type coolers. Lighter weight, improved performance, reduced fuel consumption.Innovative features

Whether custom designed to fit a customer's specific needs, or one of our proven off-the-shelf solutions, our line of speed and temperature sensors are perfect for everything from high altitude, high performance aircraft to ground-based turbine and industrial applications.
Unison sensors are made rugged enough to withstand temperature and vibration extremes, stable enough to withstand high overpressure and pressure transients, and sensitive enough to provide accurate controls. Sensor types include temperature-sensitive fluid-filled bellows assemblies, Type K or E thermocouples, Resistance Temperature Detector (RTD), and magnetic speed sensors. From prototype to production, Unison has custom solutions for even the most demanding sensing requirements and budgets.

Using our extensive experience and specialized production facilities, we have the ability to design and build custom switches that meet the unique specifications of our customers' needs. Our best sellers include our limit, precision, snap-acting, position, fuel flow and pressure switches.
Pressure Switches
Unison pressure switches are designed to perform in the harshest environments on the ground and in the air. Able to withstand temperatures ranging from -320 F to 1050 F and pressures up to 15, 000 PSI, our precision- crafted switches are engineered to endure the hostile vibration, shock, pressure, and temperature conditions inherent in today's operating environments. Unison's snap-acting pressure switches offer greater set point stability, vibration resistance, over-pressure capability and cycle life. Our capabilities include absolute, gauge and differential pressure switches as well as differential gauges.
Limit Switches
Unison limit switches are custom designed for the rigors of your application. We offer a variety of actuation and de-actuation mechanisms, including rollers, plungers and buttons. Single-pole and multi-pole, single and double throw designs are also available. We specialize in switches for extremes in temperature, shock and vibration, corrosion and other hostile environmental conditions, as well as switches with longevity requirements.

Unison can design and build custom bellows with smooth contours, uniform wall thickness, and greater strength for any application, in any industry.
Custom Designed Precision Components
From high stress oil-extracting equipment to pressure controls on space missions, Unison bellows are custom engineered to perform under stress, shock, vibration and corrosive agents. Our state-of-the-art manufacturing facilities can accommodate prototype, short runs and long-term volume production. We provide intelligent solutions that include theoretical analysis, design, material selection, manufacturing, testing, field evaluation and serviceUnison bellows are the perfect solution for applications that require utmost precision. Our manufacturing techniques allow us to maintain tight tolerances on critical dimensions, even holding the outer diameter to within a +- 0.005" margin.

The state-of-the-art investment casting facility is a key element of our vertical integration. In house design with rapid prototyping tied directly with on-site manufacture allows for quick turns through the design cycle and fast response to operational needs.

Unisons flexible joints are designed to reduce stresses, allow for movement, and allow for ease of assembly of tubing systems. With over 100, 000 installed, our high life design has proven performance.
