Terminals and Terminal Blocks
What are Terminals and Terminal blocks?
SNK Terminals are a type of industrial control terminal that is used in industrial automation, process control, and other applications. These terminals are designed to provide a secure and reliable connection between the user and the machine. They are typically used to control machinery, monitor production processes, and manage data. SNK Terminals are available in a wide range of sizes and configurations, allowing them to be used for many different types of applications.
Modular terminals are components that can be used to connect two or more devices together in a network. They are typically used to connect computers, servers, routers, switches, and other network devices. Modular terminals are often referred to as RJ-45 connectors because they use an 8-pin RJ-45 connector.
A terminal block is a type of electrical connector used to connect two or more wires together. It typically consists of a metal or plastic housing containing multiple terminals, which are the points at which the wires are connected. Terminal blocks are commonly used in industrial and commercial applications to provide a secure connection between electrical circuits.

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
