Electrical Connectors
What is a Connector?
A connector is an electromechanical device used to join two electrical parts together, generally this would be connecting a cable to a system or cable to another cable within an electrical circuit. There are many different types of connectors that can accomplish this. They can be used to connect power, data and fibre and can come in different shapes, sizes and materials. They can also be waterproof, dustproof and heat proof to various industry ratings. Our sales team is ready to help you with any queries.
What Do We Supply?
We offer a broad range of electrical connectors, including:
Appliance couplers
Hazardous area connectors
'Buccaneer' sealed connectors
General purpose connectors and accessories

The quality and reliability of their products is second to none and we are delighted to be a distributor for them. We distribute throughout the UK from our premises in Dukinfield, Cheshire, and aim send as many orders out for next day delivery as possible.
As a company we are driven by what might be seen as ‘old fashioned’ values of making sure we return phone calls when asked, and treating customers with respect. Ultimately, great customer service is important to us and one of the reasons why we have thrived as a company.
We are not old fashioned in our processes and operations, however. Our processes are all computerised ensuring that our operations run smoothly.
We offer flexible payment terms for our customers too.
Our excellent customer service is also reflected in our provision of expert technical assistance and advice that our highly experienced staff can provide over the phone, which our customers use and find invaluable.
First Vent Detection | Patented Rate of Change Algorithm | Automotive Grade
The Battery Safety Electrolyte Sensor (BES) is an automotive-grade sensor designed for early detection of venting and thermal runaway in battery systems. Utilizing an advanced and patented rate of change algorithm, the BES detects battery electrolyte vapor commonly released during the initial venting phase called First Vent, as well as hydrogen and carbon monoxide gases released during a thermal runaway event.
The ability to detect the First Vent provides an essential early warning for potential thermal runaway incidents in Lithium-Ion battery packs. This proactive early detection facilitates timely and appropriate mitigation measures, significantly reducing the risk of thermal runaway. BES employs a patented advanced rate of change algorithm designed to identify significant changes in the concentration of target gases within a sealed battery pack. This innovative method effectively reduces the occurrence of false negatives that may be seen with conventional ppm-based sensors, which focus on precise target gas threshold monitoring. The algorithm is tuned to prevent false positives, improving the end-user experience. Furthermore, the algorithm is supported by more than 12 years of rigorous research and validated through seven years of practical field deployment.
This extensive experience not only enhances the reliability of the detection algorithm but also underscores its effectiveness in real-world applications. BES enhances the safety and reliability of automotive battery systems.
Features:
Responsive to battery electrolyte vapor released during the first vent (before thermal runaway)
Responsive to hydrogen gas released during thermal runaway
Responsive to carbon monoxide gas released during thermal runaway
Patented rate of change algorithm to mitigate false negatives
Resistant to siloxane poisoning
Compatible with all Lithium-ion battery chemistries and cell types
Automotive product with CAN 2.0B output with diagnostic features
Tested for performance life of 15 years
Applications: Sealed lithium-ion battery packs or modules used in
Electric Vehicles
Hybrid Vehicles
Other On-Road Applications
Value to Customers:
Enhanced Asset Protection: Battery electrolyte vapor monitoring provides early warning of thermal events, enabling thermal runaway prevention and asset preservation
Reliable Battery Health Monitoring: BES responds to multiple gases that are typically released during thermal runaway, therefore increasing detection reliability and reduces false negatives
Ease of Integration: The rate of change algorithm eliminates the need for precise target gas threshold testing and validation. As a result, it significantly reduces integration costs and timeline
