Custom Sensor Cable and Sensor Wire

Sensor CableGalaxy supplies a full range of vented and unvented multi-conductor cables for various sensor, transducer, and transmitter markets. Galaxy can supply various types of sensor cables, both stock and custom, in various AWG sizes, voltage ratings, compounds, shielding constructions, and conductor counts. Galaxy can also recommend the correct sensor cable for specific applications.

What is Sensor Cable?

Sensor cable is a cable construction designed for optimal performance of signal/data transmission from a sensor, transducer, or transmitter to a control unit. Pressure, liquid, temperature, and flow are just a few of the measurements that can be taken.

Benefits of Sensor Cable

Sensor cables are often designed with a specific application in mind, which can vary. Galaxy can assist in engineering a cable with a vent tube, strength member, shielding, water-blocking elements, critical OD, and other features.

Sensor Cable Applications

There are many applications for sensor cables, and variations by industry and intended use. Many of the sensors used across a wide variety of applications are piezoelectric sensors, which measure changes in pressure, acceleration, strain, or force. Galaxy designs and supplies cables for the following sensor applications in the marine, military, aerospace, industrial, wind energy, driverless cars / autonomous vehicles and oil & gas industries:

  • Submersible level – well, tank level, ground and surface water measurement applications
  • Pressure – industrial, automotive, aerospace applications to measure oil, gas, and water
  • Temperature – measurement of temperature of a number of ambient environments
  • Position sensors – construction equipment, building control, weighing systems
  • Vibration sensors – railway, aerospace, automotive measurement in critical applications
  • Traffic sensors – speed and red light camera, weigh-in-motion and vehicle classification
  • Driverless Cars / Autonomous Vehicles – cameras and visual/motion detection systems

Galaxy Differentiators / Advantages for Sensor Cable

Sensor Cable Cross SectionGalaxy designs and supplies numerous sensor cables for a number of industries, with the understanding that the sensor cable can be the critical difference between whether a piece of equipment works or not. Galaxy knows the materials and constructions that will achieve the perfect custom cable solution for a specific end use, ensuring that reliable signal transmissions or electrical readings will be met.

Galaxy Success Story – Case Study

A potential new customer came to Galaxy looking for a sensor cable to be used in a seismic sensor application. Previously the end user had been combining two different name brand cables to accomplish this objective. While this two-cable setup was “working”, the engineering team knew it would not be a long term solution. After discussing the project and their goals with Galaxy, a newly designed sensor cable was manufactured. The cost of the newly designed cable was lower than the previous two-cable setup. Most importantly, the customer was able to take their product to market with great success.

Sensor Cable Technical Specifications

Galaxy offers sensor cable in the following ranges of technical specifications:

  • Gauge: 30AWG – 10AWG
  • Voltage: Specific to application
  • Temperature: -70 ⁰C – +200 ⁰C
  • Shielding: Braid, Foil, Serve, or combination
  • Strength Member: Kevlar or aramid fiber can be added to support weight strain on the cable
  • Vent Tube: Hollow tube in center of cable to allow for changes in pressure without affecting the accuracy of the readings

FAQs about Sensor Cable

How do I select a cable insulation and jacket that are right for my application?

Many factors come into play here. It is necessary to consider temperature, voltage, abrasion resistance, flexibility, and chemical compatibility. Galaxy often works with customers to learn about where the cable will be used and what its function will be to help select the materials for optimum performance. See table above describing various choices/options.

What is the reason for a vent tube in a cable?

The vent tube can be made of either nylon or polyethylene and runs the length of the cable down its core. It allows for changes in atmospheric pressure so as not to affect the pressure reading in gauge type sensors.

Terminology Notes
