The OPTIMASS 6000F is defined by the sensor VE code VEab…j...k…l…n…q... where “l”defines
the hazardous areas approval, “ab”= 71, 72, 73, 74, 75, 76, 77, 78, 79 or 80 and “n”= 1 or 2, and "j"
= 0
The OPTIMASS 6400C is defined by the sensor VE code VEab…j...k…l…n…q... where “l”defines
the hazardous areas approval, “ab”= 71, 72, 73, 74, 75, 76, 77, 78, 79 or 80 and “n”= 0, and "j" = 0
The markings for the OPTIMASS 6000F / 6400C are shown in the following tables:
