CO sensor

for automotiveCAN Busthermal runaway

The Dafo Vehicle CO sensors are engineered for early detection of CO emissions that signal potential thermal runaway in Li-ion batteries and fires in electrical cabinets. With advanced signal processing, these sensors detect CO emissions, temperature, and humidity to provide reliable detection in diverse environmental conditions. Designed to be installed within or near battery packs, the CO sensor excels in the early detection of battery failures. It is also effective for other fire-related events involving CO release. Housed in durable, automotive-grade polymer, the sensor is available in a compact PCB version (model 55-2656-05), perfect for tight spaces, with a thickness of less than 7mm for custom installations. Data transmission occurs through a CAN bus interface, utilizing a standard M12 connector for seamless power and communication integration. Real-time temperature and humidity monitoring further enhance the sensor’s reliability, enabling it to contribute to sophisticated alarm algorithms. Compatible with Dafo Vehicle's CEV-3 and CV-X control units, the CO sensor can also connect to any CAN bus network or operate independently with its solid-state output. For added functionality, the CO sensor can connect to Dafo Vehicle's linear heat detector. This setup allows the CO sensor to act as a pre-alarm, shutting off the battery pack in the early stages, while the linear detector manages fire suppression. CO Sensor Models Available: • 55-2656-00 – Standard version • 55-2656-05 – PCB version for compact applications • 55-2656-06 – Features daisy-chain connectivity for multiple sensor setups
