Amphenol SGX Sensortech VQ548MP2-DA Catalytic Combustible Gas Sensor offers a robust, low-power, and poison-resistant package (16mm x 20mm) with a certified flameproof enclosure. This sensor is designed for low-power operation in continuous mode and provides additional ultra-low power consumption when used in pulse mode operation. The VQ548MP2-DA sensor features low-power battery operation, high resistance to mechanical shocks, and low orientation effect. Amphenol SGX Sensortech VQ548MP2-DA Catalytic Combustible Gas Sensor is ideal for battery-operated devices. This MEMS catalytic gas sensor provides the basic sensor performance that will enable a suitable instrument to meet the various (Group 1) mining and industrial (Group 2) performance standards.
