E-T-A Power relays are reliable problem solvers when it comes to switching high currents. Particularly construction machinery, agricultural vehicles as well as buses and trucks, floor-borne vehicles and other special vehicles (e.g. fire brigades) often have connected large electrical loads. In these applications, power relays disconnect the entire on-board electrical system from the battery.
Depending on the application, E-T-A offers purely electro-mechanical relays, solid state relays and also a hybrid design consisting of an electro-mechanical switching system with an intelligent electronic control unit.

MSM II-Switch with M12 Connector
With the new switch from the MSM II family with M12 connector (8 pins), Schurter is focusing on a solution that has been specially developed for demanding industrial and commercial applications. Thanks to the M12 connector system, robust construction, and integrated RGB illumination, this switch combines maximum reliability, functionality, and modern design in a compact unit.
The standardized M12 connector ensures fast, secure, and error-free installation—without any complicated wiring. Thanks to the fixed pin assignment, wiring errors are effectively avoided, which not only simplifies installation but also speeds it up considerably.
The mechanical design is made for permanent industrial use—shockproof, vibration-resistant, and resistant to tough environments. This means the switch will keep working reliably for years, even in extreme conditions.
The three-color RGB illumination provides clear status indication or individual signals. Example: green = active; red = off; flashing orange = error condition. This makes the switch ideal for machine controls, control systems, or user interfaces.
The new Schurter MSM II M12 switch is suitable for applications where installations must be made quickly, easily, and safely. It is used in industrial automation, machine and plant engineering, as well as in public and commercial areas where clear signaling and high reliability are required.

Honeywell BES 24V - An extension of the Honeywell Battery Safety Sensor Portfolio
First Vent Detection | Rate of Change Algorithm | Automotive Grade | 12V & 24V Options
Honeywell has released its 24V Battery Safety Electrolyte Sensor (BES), an extension of the previously launched BES Series. This product extension enables the seamless integration of the BES Series into high‑voltage battery packs that operate on 24V. The Honeywell battery safety sensor portfolio is designed to enhance safety in lithium‑ion, on‑road, and stationary battery applications.
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.

Coin Cell Supercapacitors SCCA, SCCC
Coin cell supercapacitors are compact electrochemical energy storage devices with a high capacity that can quickly store and release electrical energy. Compared to conventional batteries, they offer several advantages, including high power density, a long cycle life, and fast charge and discharge rates.
Power density describes how quickly an energy storage device can release or absorb energy. This is important for applications requiring short-term high energy outputs, such as starting an engine. Supercapacitors have a high power density, which enables them to provide energy quickly. Energy density
indicates how much energy a storage device can hold over a longer period. A high energy density is essential for applications requiring a continuous energy supply.
The new coin cell supercapacitors from Schurter are available for horizontal mounting (SCCA) or vertical mounting (SCCC). They can be used in systems with a voltage of up to 5.5 V and have a capacitance value ranging from 100 to 1,500 mF.
Schurter's new coin cell supercapacitors are used in a variety of applications, including backup power supplies, electronic devices, renewable energy systems and medical devices. While they are most commonly used for real-time clock backup, they can also be used for memory backup, battery swap ride
through and LED or audible alarms.
