Fibre optics

Covering a wide range of specialist fibre optic cables, connectors and assemblies for all applications, we can work with you to select the right fibre for your system - whether operating in single-mode or multi-mode. We also define the correct cable and connection system to meet the specific environmental operating conditions of your system, then manufacture a bespoke solution at our purpose-built facility.

We also specialise in fibre and connector cable assemblies for harsh environments, and can incorporate a range of technologies such as multi-mode, single-mode, expanded beam technology and physical contact/butt joint technology to produce anything from a standard ruggedised cable to a hybrid, ruggedised solution incorporating fibre, copper and coax which is able to carry data, signal and power in one cable.

We offer a unique fibre optic / hybrid fibre optic and copper cable assembly service for commercial, industrial and harsh environments.

We have over 20 years of experience in the design and manufacture of both fibre only and hybrid fibre/copper cables. We have designed, produced, and installed cable assemblies for many diverse environments, including nuclear submarines, oil exploration vessels, trains, open cast mines and roadside traffic gantries.

We supply optical and electrical transceivers, Direct Attach Cables (DAC), Active Optical Cables (AOC), break-out cables, and form-factor adapters that have been fully qualified using original network equipment manufacturers delivering full compatibility to most major brands on the market today.

Our cages and connectors are offered in a variety of configurations allowing maximum flexibility during design and board layout, accommodating belly-to-belly applications using single 1xN cage types, stacked assemblies with integrated light pipes, connectors simplifying the placement process onto the PCB.

We have the capability to manufacture custom ruggedised and harsh environment cable assemblies to customer specifications, supporting volumes from test cable sets to full production. These high-performance circular connector based assemblies are perfectly suited for use in demanding environments ranging from outdoor installations to high corrosion environments.

Ruggedised custom assembly

Custom cables and connectors

We design and manufacture custom-made cable assemblies, harnesses and flexes to create the best inter-connection system for your application, using solutions from world-class manufacturers.

Our service encompasses manufacturing from pre-defined drawings to your exact specifications, through taking a design and sourcing the most cost-effective components to a complete design service.

Delivered ready to install

Your cable assembly or harness will be manufactured in one of our ISO9001 accredited technology centre facilities offering you the following benefits:

  • Designed to meet your needs – our first-article sampling process will ensure that all subsequent assemblies or harnesses will be right first time.
  • Fully tested – all assemblies and harnesses can be tested for continuity and shorts, giving you the confidence to install directly into the production line from the box.
  • Standards compliance – manufacturing in France and Asia is in accordance with UL and IPC norms.
  • Total cost of ownership reduced – cable assembly or harness is supplied, ready to be installed, reducing the time it takes to assemble the system.
  • State-of-the art logistics – including just-in-time, Kan-ban, ship-to-line and buffer-stocking to agreed levels support your inventory and cash-flow.
Sensors

Custom sensor services

With access to the R&D teams behind the world’s most advanced sensing technologies, we can design, develop and build custom sensor assemblies quickly and easily. By combining our own in-house knowledge and experience with the skill and resources of our supplier partners, we can help you to develop groundbreaking designs which incorporate the most advanced sensing technologies.

We can design, build and assemble single or multiple sensor assemblies that achieve the most rigorous criteria for accuracy, repeatability and long-term reliability.

Custom sensing assemblies are particularly useful for harsh or high-end applications such as industrial, military and aerospace, medical, and transport systems. Our objectives are always to help you to increase sensing accuracy and reliability, whilst carefully controlling the overall cost of your end product.

Our programmable rotary shafted sensors offer a competitive package ideally suited for robust and harsh environment applications. Featuring an IP68 sealing and an operating temperature of up to 150°C, the main sensor housing is manufactured from high-grade temperature resistant plastic with anodised aluminium alloy mounting.

With redundant output, these compact and fully non-contacting Hall Effect sensors will perfectly suit arduous high-duty cycle position feedback applications.

Both versions offer programmable angle selection and a choice of U-shaft, D-shaft and spring coupling mounting options as standard as well as numerous input and output options. The CRSS version also offers the capability to have bespoke mounting from 32mm upwards in any stud configuration, which may be customised to exactly suit your application.

Key features:

  • Customisable mounting and shaft
  • Hall Effect non-contacting technology
  • Form, U, D shaft and spring coupling drive shaft as standard
  • Long-life - extremely robust
  • Programmable angles from 30º up to 360º
  • IP68 protection
  • Redundant output

You know what temperature range you want to measure, but selecting the right combination of sensing elements and housing is a challenge. We have over 20 years' experience in advanced technology solutions, including the design and delivery of custom temperature probes designed to meet your specific requirements, and reduce your time to market.

Designed for your project

Temperature is the most widely measured of all physical properties. Designing a temperature probe to work effectively in any given application is challenging. Consideration must be given to which technology to use – RTDs, thermistors, thermocouples or thermopiles, and protection of these elements in the environment. Fully understanding the effect this protection has on the element's characteristics to make sure it will work correctly once assembled. Finally, how the probe will be mounted and connected to the electronics, which are often remote from the point of measurement. We understand these issues and advise on the best element, housing, cable and connector solution for any application, delivering a custom-designed temperature probe assembly usually within six weeks.

We work with you to understand the environment the sensor is to be used in and design a suitable housing and add the appropriate cable and connectors to ensure you have the best bespoke solution for your application.

Our extensive range covers all key parameters for any environment, but to help solve more complex challenges for your application, we can design and build a complete solution to your needs with customer-specific combinations.

From simple sensor combinations to complete, custom products, we can also combine multiple sensors with wireless connectivity, display/controllers and enclosures. Covering:

  • Display / Controller - Whatever you require, we can build it into a solution for you
  • Enclosure options - We can work with your design team to specific requirements
  • Interface options - HMI / display / packaging
  • Wireless options - Wi-Fi / Bluetooth / LoRa / RF
  • Sensor options - Temperature / HCHO / VOC / RH / CO2 / PM (1.0, 2.5, 10.0)
  • Cable & connector options
