RS-232C Interface Sensor Data Unit (FQ-SDU2@)
For the I/O connector harness, use an FQ-VP2@@@ Parallel Cable for the FQ-SDU2 or a MIL-standard
harness, such as the OMRON XZ2F. (The Cables are sold separately.)
Signal Application
Power supply (24 V)
These terminals are for the external power supply (24 V).
• Wire the power supply separately from other devices. If the wiring for other devices is placed
together or in the same duct as the wiring for the Vision Sensor, the influence of electromagnetic
induction may cause the Sensor to malfunction or may damage it.
• Do not allow the load current to exceed 50 mA. The output circuit may be damaged if the load cur-
rent exceeds 50 mA.
