Overview
The CDMER-625A is the Environmentally Resistant (ER) version of the CDM-625A. It offers added protection in more aggressive operating environments that have a higher concentration of dust, sand and salt. The ER version uses an application of Urethane Conformal Coating (CC) and critical interface protective covers for enhanced protection against dust, sand and salt. Special protective Conformal Coating and protective covers have been designed to ensure that the CDMER-625A meets MIL-STD-810G requirements including Method 510 Procedure I (Blowing Dust), Method 510 Procedure II (Blowing Sand) and Method 509 (Salt Fog). Both the CC and protective connector covers are non-nutrient fungal growth materials. The ER version also provides an extended operating temperature range of 0 to 60º C. The ER version is not designed to be used in an un-controlled environment or outdoor application. The ER version carries the same two year standard warranty as other Comtech EF Data products.
