TENTATIVE PRODUCT INFORMATION CMM5042 - Pre-calibrated Module for CO Gas The CMM5042 carbon monoxide sensor module is a new unit which utilizes TGS5042, Figaro's electrochemical CO sensor, a widely used model for residential and commercial CO detectors with excellent durability and long term stability. This module provides analog output voltage proportional to CO concentration. CMM5042 is capable of detecting sensor trouble. Customers can easily design CO detectors with the ready- to-use module. Features: * Ease of use * Linear analog output proportional to gas concentration * Maintenance free * Battery operable Applications: * Residential and commercial CO detectors * Ventilation control * CO monitor for gas boilers, kerosene heaters, etc. Pin No. Name Description

Operating temperature*1,2 0˚C ~ +50˚C (continuous) -5˚C ~ +55˚C (intermittent) Operating humidity 5 ~ 95%RH Response time (T90) within 60 seconds Storage conditions*1,2 -5˚C ~ +55˚C/5 ~ 95%RH Dimensions 56 x 29 x 22mm Weight approx. 19g *1 If the water in the reservoir should freeze very rapidly (typically occurs only under artificially created conditions), irreversible change of sensor characteristics would occur. To avoid this risk, the sensor is recommended to be positioned with its cap (working electrode) facing up. *2 Please contact Figaro for more information if the required temperature range would exceed the specified limits.
