Siemens SIWAREX EB Extension Box


Siemens SIWAREX EB Extension Box serves the purpose of extending the connecting cables of load cells. Load cells can be linked in either 4-wire or 6-wire configurations. When connecting cables to the weighing module or JB junction box, it’s essential to use a 6-wire system. For this, it’s recommended to use the 7MH4 702-8AG or …-8AF SIWAREX connection cable. If you extend load cell cables to a JB junction box, remember to replace the M16 x 1.5 cable glands on the box.
