The 6-pin type modular connector should be used for the connection to the H-PCP-J module.
Recommended model: TM4P-66P (Manufactured by HIROSE ELECTRIC CO., LTD.,)
Because there is not SG, in case of SYSMAC CS1 series, electric wiring is unnecessary.
Customer is requested to prepare a communication cable fit for the control unit to be
connected by the PLC.
 Connection using our cable
Connection cable W-BF-01 * (RKC product) can be used to connect the PLC. If noise is a factor,
customer should use a twisted pair cable (not included) or something to that effect.
* Shields of the cable are connected to SG (No. 6 pin) of the H-PCP-J connector.
The details of the connectable connector for the PLC please also read the instruction manual
for the used PLC.
