The first shipments of the new supercompact RF602 revealed problems with cable fasteners.
Our company apologizes for any inconvenience this may cause.
We'd like to inform you, that we changed design of cable fixing.
Now we use the same method as in the RF603 sensors, and this completely closes the problem. In addition, now all sensors are equipped with a standard cable, and its length of 5 m is included in the price of sensors (as in the RF603 series).
Detailed Manual is available here.
New picture of RF602 sensors is here.
