Electronic Products and Expert Reviews

MRO delivers quality cables, wiring harnesses, rack builds, electronic enclosures, control panels, control systems and more. We also deliver the answers to very complex and sometimes daunting questions that could change the course of history, or at the very least, impact science and peoples lives. One exciting project that MRO provided expertise and product for was a cutting-edge telescope.

In British Columbia Canada, there is a facility known for science and technology research called the Dominion Radio Astrophysical Observatory, or “DRAO”. The facility is internationally known and is home to astronomers, astrophysicists, engineers and technologists, all working towards the design and development of world-class instrumentation. One of these leading-edge projects is the CHIME telescope.

When the CHIME radio telescope was under construction, they required specialized cable assemblies with high signal velocity capabilities. The project was extraordinarily complex, consisting of fixed linear reflectors with a bridgework of many antennas at the focal plane of the reflector. There are several reflectors. The signals from each antenna are connected to a coaxial cable. These signals are cabled into a combiner. The important thing is they have to be very precise in phase. It is not much different from an optical lens where all the rays of light have to focus at the same point or the image will be fuzzy. The time the signal travels from one end of the cable to the other has to be the same for each cable, give or take 1 nanosecond. A rough definition of a nanosecond is the time it takes light to travel one foot in a vacuum.

Even with the same type of cable from the same lot, the transit time will vary, so a method had to be found to measure that time. A couple of methods were tried, and the optimum one was a network analyzer. We used an Anritsu S331E. The astronomy staff at the UBC wrote a script that allowed the cable serial number barcoded and linked to the cable loss and the electrical length of each unique cable.

Our Schleuniger automated cable cutting and reeling machine was set up to cut over 2000pcs of these 50-meter cables very consistently, however, getting all our cable for that job from the same lot, a number of cables were out of tolerance and had to be re-terminated if they were too long, even though the physical length was within the specification. The short ones were repurposed.

General Dynamics Systems Canada is a global aerospace and defense company. Manufacturing products from Gulfstream business jets and combat vehicles to nuclear-powered submarines and communications systems, people around the world depend on their products and services for their safety and security. MRO is thrilled to have worked with General Dynamics, who had this to say about our work:

MRO has a proven track record of consistently exceeding our strict specifications, challenging requirements and aggressive lead times. Our Military Spec Cable Assemblies require superior manufacturing techniques, not common in conventional cable assembly manufacturing. MRO has the required experience and capabilities for our Military Specifications and complex designs. Effective communication is MRO’s strongest point. Particularly, openness to listen. Recently, we introduced MRO to some of our end customers. The key takeaway was that they were impressed with MRO’s understanding and execution of the customers’ complex designs.

MRO has become an integral part of our success by effectively delivering tight schedule requirements, from large orders to small design verification. On time and with a high level of quality.

Vertically Integrated Manufacturing Dynamic for a broad range of industries

MRO Electronic Supply offers a suite of vertically integrated manufacturing solutions across a broad range of sectors. We are able to offer our clients world-class quality, engineering and services because of these 8 capabilities and approaches.

MRO is confident we have the relationships and know-how to avoid these pitfalls.

Leveraging the 5 Pillars of Manufacturing

There is a well-known manufacturing theory that was first made famous by Toyota. The theory dictates that there are 5 pillars for lean or successful manufacturing. MRO is committed to achieving these 5 pillars of manufacturing for every product and customer.

  1. Value: MRO understands that the value of our products is based on the needs and wants of our clients. We are committed to providing our customers and clients with the quality product they want at a price point that is fair. We know that a cable is more than a cable, it is an integral component of the client’s larger puzzle.
  2. Value stream: MRO Electronic supply believes that the products we produce are more than just the finished product. We know how much goes into each wiring harness, rack build, electronic enclosure, control panel, or control system. There is a process and supply chain behind each of these products. We have been in this business for more than two decades, we know what the value stream looks like and we know how to successfully achieve it.
  3. Flow: At MRO Electronic supply, our vertically integrated manufacturing dynamic ensures that we are developing the product that our customer expects in the most efficient and thoughtful manner possible. MRO removes the silos and works across the company and with the client to produce the best possible solution for our client.
  4. Pull: MRO’s NPI/First Article Inspection process is set up to provide rapid turnover for full production for time sensitive projects. This means that while we love producing custom solutions, we can provide our NPI at rapid speed when needed. MRO is focused on providing the highest quality service to our customers.
  5. Perfection: MRO lives and dies by the quality of our products and solutions. This is why every product that leaves our manufacturing facility undergoes 100% testing to ensure it is reliable for operations upon delivery and can withstand different field applications. To date, MRO has maintained a quality rating of 99.7% for all of our shipped products. We are committed to providing our customers as close to perfection as is possible.

Dependable high-quality products delivered to industries

MRO provides high-quality products and unwavering service across industries. Some of our most notable industries include defense, mining, robotics, and oil and gas.

For more than six years MRO has been a reliable partner for prime contractors in the defense industry. Providing electronic manufacturing services for custom cable assemblies, wiring harnesses and box builds for military vehicles, shipboard electronic systems, combat and communications systems, and other command and control electronic systems for our defense partners located in North America and Europe.

Mining in today’s world means you need tough and reliable connectivity solutions. Damage due to abrasion, vibration, tension and cut-throughs are frequent. Down time is costly, and at MRO we understand your need to know that you can keep operating, even in the harshest conditions. Our team has many years of experience providing rugged cable assemblies for vertical and horizontal power feeds, data acquisition, onboard systems, seismic telemetry, sensors, cameras, proximity transducers, GPS antennas, and other devices.

We have worked extensively with Oil & Gas clients to provide custom cable assemblies and other connectivity solutions that are rugged and able to withstand the hazardous and harsh environments of the oil fields. Our in-house overmolding team has produced thousands of custom molds to increase durability and solve the unique problems found on land and sea rigs. We also have an extensive selection of durable jacket options (including steel braiding) to protect against abrasion, extreme heat, and other harsh elements.We have experience providing connectivity solutions for land-based oilfield drilling, well sites, production platforms, offshore drilling, pump rooms, logging systems, measurement-while-drilling, seismic systems, data acquisition and telemetry, and more.Robotics cable assemblies are at risk of failure due to twisting and turning over the course of thousands of cycles, as well as the wear that comes from operating in industrial environments. In order to reduce downtime, industrial robotics cable assemblies need to be able to withstand high torsion and harsh operating environments. At MRO we can manufacture custom robotics cable assemblies with continuous flex cable that will resist wear and tear—reducing your downtime and saving you money.
